[Aikido] Fix 70 security issues in axios, form-data, next

[aikido-autofix]

Problem

Upgrade axios, form-data, and next to fix critical SSRF, prototype pollution, and proxy bypass vulnerabilities.

Changes

✅ 70 CVEs resolved by this upgrade, including 7 critical 🚨 CVEs

This PR will resolve the following CVEs:

Issue	Severity	Description
CVE-2026-42043	🚨 CRITICAL	[axios] An attacker who can influence the target URL can bypass NO_PROXY protection by using any address in the 127.0.0.0/8 range (except 127.0.0.1), allowing requests to reach unintended destinations. This enables potential information disclosure or unauthorized access to local services.
CVE-2025-62718	🚨 CRITICAL	[axios] Improper hostname normalization in NO_PROXY rule checking allows requests to loopback addresses (localhost., [::1]) to bypass proxy protections, enabling proxy bypass and potential SSRF attacks against internal services. This vulnerability permits attackers to reach sensitive services despite configured NO_PROXY protections.
CVE-2026-42264	🚨 CRITICAL	[axios] Prototype pollution vulnerability in HTTP adapter allows attackers to exploit five config properties (auth, baseURL, socketPath, beforeRedirect, insecureHTTPParser) without hasOwnProperty guards, enabling RCE or request manipulation when Object.prototype is polluted by other dependencies.
CVE-2026-42044	🚨 CRITICAL	[axios] Prototype Pollution vulnerability allows attackers to manipulate JSON API responses through a polluted parseReviver function, enabling privilege escalation, balance manipulation, and authorization bypass. The default transformResponse function unsafely calls JSON.parse with an unvalidated parseReviver parameter from the config object.
CVE-2026-44494	HIGH	[axios] Prototype pollution vulnerability allows escalation to Man-in-the-Middle attacks by injecting a malicious proxy into the prototype chain, enabling interception and modification of all HTTP traffic including authentication credentials. An attacker can read and alter all application HTTP communications through a compromised dependency.
CVE-2026-44490	HIGH	[axios] Axios contains prototype pollution gadgets that allow upstream dependencies to inject malicious values into HTTP headers or cause synchronous TypeErrors on every request. This enables information disclosure or denial of service attacks when Object.prototype is polluted by other libraries.
CVE-2026-44495	HIGH	[axios] Contains prototype-pollution gadgets in request config processing that could be exploited if Object.prototype is already polluted by another vulnerability, potentially allowing arbitrary code execution or request manipulation. Requires a separate prototype-pollution vulnerability or prior attacker control over Object.prototype to be exploitable.
CVE-2026-40175	HIGH	[axios] A prototype pollution vulnerability in a third-party dependency can be exploited to inject unsanitized header values into outbound HTTP requests. This allows attackers to manipulate request headers, potentially leading to request smuggling, cache poisoning, or other header-based attacks.
CVE-2025-58754	HIGH	[axios] A vulnerability allows attackers to supply large data: scheme URLs that bypass memory limits, causing unbounded memory allocation and process crashes (DoS) on Node.js. The issue affects versions 0.28.0 through 0.30.1 and 1.x before 1.12.0.
CVE-2026-25639	HIGH	[axios] The mergeConfig function crashes with a TypeError when processing configuration objects containing proto as an own property, allowing attackers to trigger denial of service. An attacker can exploit this by providing a malicious configuration object created via JSON.parse().
CVE-2026-42038	HIGH	[axios] Incomplete hostname normalization in no_proxy bypass allows requests to IP loopback addresses (127.0.0.1, [::1]) to route through proxy when no_proxy=localhost is set, enabling proxy bypass circumvention. This occurs due to pure string matching without IP alias resolution.
CVE-2026-42039	HIGH	[axios] A deeply nested object passed as request data causes the toFormData function to recursively walk without depth limits, crashing the Node.js process with a RangeError (Denial of Service). This vulnerability allows attackers to trigger application crashes through maliciously crafted nested payloads.
CVE-2026-44486	HIGH	[axios] Axios' Node.js HTTP adapter leaks proxy credentials to redirect targets when following redirects through authenticated proxies, allowing the Proxy-Authorization header to persist on redirected requests. This information disclosure vulnerability affects Node.js environments with automatic redirects and authenticated proxy configurations enabled.
CVE-2026-44487	HIGH	[axios] Axios's Node.js HTTP adapter may leak Proxy-Authorization credentials to redirected origins when following redirects from proxied to direct connections, allowing credential disclosure. This occurs when an authenticated proxy request redirects to a non-proxied URL, potentially exposing proxy credentials to the final destination.
CVE-2026-44488	HIGH	[axios] The fetch adapter fails to enforce configured request and response size limits (maxContentLength, maxBodyLength), allowing oversized bodies to be processed and causing potential resource exhaustion or denial of service attacks.
CVE-2026-42033	HIGH	[axios] A prototype pollution vulnerability allows attackers to intercept and modify JSON responses or hijack HTTP transport to access credentials and headers. This requires prior prototype pollution from a co-dependency but enables complete request/response manipulation.
CVE-2026-42035	HIGH	[axios] A prototype pollution gadget in the HTTP adapter allows attackers to inject arbitrary HTTP headers into outgoing requests by polluting Object.prototype with specific properties. This enables header injection attacks that could lead to request manipulation and potential security bypasses.
CVE-2026-42041	MEDIUM	[axios] A Prototype Pollution vulnerability allows attackers to suppress HTTP error responses by polluting Object.prototype.validateStatus, causing all status codes to be treated as successful and bypassing authentication and error handling.
CVE-2025-27152	MEDIUM	[axios] Axios sends requests to absolute URLs even when baseURL is configured, bypassing intended routing and potentially causing Server-Side Request Forgery (SSRF) and credential leakage in both server and client environments.
CVE-2026-42042	MEDIUM	[axios] Uses truthy/falsy semantics instead of strict boolean comparison for XSRF token protection, allowing attackers to bypass same-origin checks via prototype pollution or misconfiguration and steal XSRF tokens sent to cross-origin servers. This enables CSRF attacks against protected endpoints.
CVE-2026-42034	MEDIUM	[axios] A vulnerability allows attackers to bypass the maxBodyLength restriction on stream request bodies when maxRedirects is set to 0, enabling oversized uploads to be sent despite strict body limits. This could lead to denial of service or resource exhaustion attacks.
CVE-2026-42036	MEDIUM	[axios] When responseType is set to 'stream', the library fails to enforce maxContentLength limits, allowing attackers to bypass response-size restrictions and cause denial of service through unbounded data consumption.
CVE-2026-42037	MEDIUM	[axios] Unsanitized CRLF sequences in the Content-Type header of multipart form-data parts allow header injection attacks when processing user-controlled Blob/File objects. An attacker can inject arbitrary MIME headers into the multipart body, bypassing Node.js v18+ header protections.
CVE-2026-42040	LOW	[axios] A character mapping in the encode() function incorrectly reverses percent-encoding of null bytes, converting %00 back to raw null bytes and potentially enabling injection attacks in certain contexts. The vulnerability has limited impact as standard axios request flows are unaffected.
CVE-2025-7783	🚨 CRITICAL	[form-data] Use of Insufficiently Random Values vulnerability in form-data allows HTTP Parameter Pollution (HPP). This vulnerability is associated with program files lib/form_data.Js. This issue affects form-data: < 2.5.4, 3.0.0 - 3.0.3, 4.0.0 - 4.0.3.
CVE-2026-12143	HIGH	[form-data] A CRLF injection vulnerability in the field and filename arguments allows attackers to inject headers or multipart parts into requests, potentially enabling form field manipulation or bypass attacks when untrusted input is used as field names or filenames.
AIKIDO-2026-553733	🚨 CRITICAL	[next] A heap buffer overflow in libheif during AVIF image processing allows unauthenticated remote code execution in the Image Optimization API. Self-hosted deployments optimizing attacker-supplied or remotely fetched AVIF images are vulnerable.
CVE-2025-29927	🚨 CRITICAL	[next] A vulnerability allows attackers to bypass authorization checks in middleware by manipulating the x-middleware-subrequest header, potentially gaining unauthorized access to protected resources. The impact is authorization bypass, which could lead to unauthorized data access or actions depending on the application's implementation.
CVE-2026-44578	HIGH	[next] Self-hosted applications are vulnerable to server-side request forgery (SSRF) through crafted WebSocket upgrade requests, allowing attackers to proxy requests to arbitrary destinations and potentially expose internal services or cloud metadata. Vercel-hosted deployments are unaffected.
AIKIDO-2026-10758	HIGH	[next] A WebSocket upgrade proxying vulnerability allows attackers to craft requests that trigger outbound connections to arbitrary destinations, enabling server-side request forgery and potential exposure of internal services. This affects self-hosted deployments and can be exploited to reach internal or external targets.

CVE-2026-44573	HIGH	[next] A vulnerability allows unauthorized access to protected page data in applications using Pages Router with i18n configuration, as middleware authorization checks are bypassed for locale-less data route requests. An attacker can retrieve sensitive SSR JSON data without passing authorization checks, resulting in information disclosure.
GHSA-8h8q-6873-q5fj	HIGH	[next] A specially crafted HTTP request to App Router Server Function endpoints can trigger excessive CPU usage during deserialization, causing denial of service (DoS).
CVE-2026-64641	HIGH	[next] Crafted requests targeting Next.js applications with App Router and Server Actions can cause excessive CPU usage, leading to denial of service by blocking request processing. This vulnerability allows attackers to exhaust server resources and prevent legitimate requests from being handled.
CVE-2026-29057	MEDIUM	[next] HTTP request smuggling vulnerability in Next.js rewrites with chunked DELETE/OPTIONS requests allows attackers to bypass route restrictions and access unintended backend endpoints. An attacker could smuggle malicious requests to internal or admin routes through request boundary disagreement between proxy and backend.
CVE-2026-64649	MEDIUM	[next] Server Actions can be exploited to perform Server-Side Request Forgery (SSRF) attacks when Host headers are not properly validated, allowing attackers to redirect requests to malicious hosts or access internal values. This affects applications on custom servers or deployments without upstream host pinning.
AIKIDO-2026-467347	MEDIUM	[next] Server-side fetch cache keys are derived from lossy text decoding of request bodies, allowing distinct requests with different bodies to share cache entries and leak confidential data between callers. The vulnerability affects the App Router and is fixed by keying the cache on raw body bytes instead.
AIKIDO-2026-339670	MEDIUM	[next] Server Action and cache endpoint identifiers are exposed in publicly served client artifacts, allowing unauthenticated users to enumerate internal endpoints and potentially exploit weak authorization controls.
AIKIDO-2026-165691	MEDIUM	[next] Server Actions on Edge runtime lack request body size limits, allowing unauthenticated attackers to send oversized requests that exhaust memory and cause denial of service.
CVE-2025-57752	MEDIUM	[next] Cache key confusion in Image Optimization API routes allows unauthorized users to access cached images intended for other users when responses vary based on request headers like cookies or authorization tokens. This enables information disclosure and potential unauthorized access to sensitive image content.
AIKIDO-2026-10755	MEDIUM	[next] Inline beforeInteractive script serialization insufficiently escapes untrusted input, allowing attackers to break script boundaries and execute arbitrary JavaScript in the browser when untrusted data is passed to script props.
CVE-2026-44580	MEDIUM	[next] A cross-site scripting (XSS) vulnerability exists in applications using beforeInteractive scripts with untrusted content, where serialized script content is not properly escaped, allowing attackers to execute arbitrary JavaScript in visitors' browsers.

AIKIDO-2026-206850	MEDIUM	[next] A cache key vulnerability in server-side fetch responses fails to account for request body differences, allowing unauthorized users to receive cached responses containing confidential data from other requests. This information disclosure vulnerability affects applications using the App Router.
AIKIDO-2026-10754	MEDIUM	[next] The Image Optimization API fails to enforce consistent maximum-size limits when loading local images into memory, allowing attackers to exhaust process memory through large local assets and cause denial of service in self-hosted configurations.
CVE-2026-44577	MEDIUM	[next] A memory exhaustion vulnerability in the Image Optimization API allows attackers to trigger out-of-memory conditions by requesting large local assets through the /_next/image endpoint without size limits. This can cause denial of service by consuming excessive server memory.
CVE-2026-44572	MEDIUM	[next] A vulnerability allows attackers to send a crafted x-nextjs-data header on requests to middleware-handled paths, causing the redirect response to use an internal header instead of the standard Location header, which browsers cannot follow. If deployed behind a caching CDN or reverse proxy, this can poison the cache and cause denial of service for affected redirect paths.
AIKIDO-2026-10753	MEDIUM	[next] A cache poisoning vulnerability allows attackers to cause incorrect React Server Component payloads to be cached and served to users under shared-cache conditions, potentially returning malformed responses and compromising application functionality.
CVE-2026-44576	MEDIUM	[next] Applications using React Server Components are vulnerable to cache poisoning due to improper response variant partitioning in shared caches, allowing attackers to serve component payloads instead of HTML and poison cache entries for subsequent visitors. This enables unauthorized content injection and potential remote code execution through malicious component payloads.
CVE-2026-64647	MEDIUM	[next] A server-side fetch caching vulnerability allows responses from POST requests with non-UTF-8 charset bodies to be incorrectly returned to different requests, potentially leaking confidential data. This affects requests to the same URL with different request bodies that produce identical cache keys due to charset encoding differences.
CVE-2026-64648	MEDIUM	[next] Server-side fetch requests with different body parameters may return cached responses from other requests to the same URL, causing confidential data leakage to unauthorized callers. This information disclosure vulnerability affects fetch calls where the request object and init parameters differ.

This could enable phishing attacks or malicious file delivery under specific configurations.
CVE-2025-48068	MEDIUM	[next] A vulnerability in the dev server with App Router enabled could expose limited source code to attackers who trick users into visiting malicious webpages during local development. This information disclosure vulnerability only affects development environments and has been patched in recent versions.
CVE-2025-32421	LOW	[next] A race-condition vulnerability in the Pages Router causes normal endpoints to serve pageProps data instead of HTML under certain misconfigurations, potentially leading to information disclosure. This affects self-hosted deployments where responses may be cached without explicit cache-control headers.
AIKIDO-2026-10752	LOW	[next] RSC cache-busting values can collide in shared cache deployments, allowing attackers to poison cache variants and serve incorrect component responses to users. This vulnerability stems from insufficient collision resistance in response variant separation.
AIKIDO-2026-10751	LOW	[next] A vulnerability in middleware redirect handling allows attackers to manipulate redirect responses and poison caches by spoofing internal-data headers, causing subsequent users to receive broken cached redirects until expiry.
CVE-2026-44582	LOW	[next] React Server Component responses are vulnerable to cache poisoning due to insufficient response partitioning, allowing attackers to manipulate cache entries and serve incorrect content to users. This can lead to information disclosure or content manipulation through collisions in cache-busting values.

⚠️ Incomplete breaking changes analysis (2/3 analyzed)

⚠️ Breaking changes analysis not available for: axios

✅ No breaking changes from either the axios (1.7.8 => 1.16.0) or Next.js (14.2.10 => 15.5.24) upgrades affect this codebase.

Axios Analysis:

The codebase uses axios in langfuse-node/src/fetch.ts where it calls axios.request() with a url parameter. The breaking change regarding allowAbsoluteUrls only affects code that uses both baseURL configuration and absolute URLs in requests. This codebase does not use baseURL with axios - it only passes complete URLs directly to axios.request().

Next.js Analysis:

The codebase contains a Next.js example app in examples/example-web-nextjs running Next.js 14.2.10. However, none of the Next.js 15 breaking changes affect this example:

• No usage of cookies() or headers() from next/headers

• No usage of params or searchParams props in components

• No usage of deprecated features like analyticsId, squoosh, geo, ip, useMDXComponents, strictNextHead, dynamicIO, rootParams, or AMP

• No usage of legacyBehavior prop on Link components

• No usage of forwardRef with Link

• No intercepting routes with output: export

• No server directives like "use server" or "use cache"

• The route handlers use export const dynamic = "force-dynamic" which is compatible with Next.js 15

• The Image component usage has clean src attributes without leading/trailing spaces

• The minimal next.config.js has no deprecated configurations

The example app is a simple demonstration with basic route handlers and does not use any of the advanced Next.js features that have breaking changes in version 15.

All breaking changes by upgrading next from version 14.2.10 to 15.5.24 (CHANGELOG)

🤖 Remediation details

Fix critical/high/medium security vulnerabilities in axios, form-data, and next

Short summary

This PR remediates security vulnerabilities in three packages — axios, form-data, and next — affecting examples/example-web-nextjs. The direct dependency next was bumped in package.json, its sibling eslint-config-next was aligned to the same version, and the transitive dependencies axios and form-data were resolved to patched versions via lockfile refresh in yarn.lock.

axios

axios is a transitive dependency pulled in by langfuse-node@3.31.0 under the declared range ^1.7.4. The lockfile had resolved this to 1.7.8, which is vulnerable across a wide range of CVEs. Because the existing parent range ^1.7.4 already admits 1.16.0 and above, no manifest change was required — running yarn upgrade 'axios@^1.7.4' refreshed the stale lockfile entry, resolving axios to 1.19.0 (≥ 1.16.0, the highest patched floor across all listed advisories).

form-data

form-data is a transitive dependency of axios, declared by axios at ^4.0.0. The lockfile had resolved it to 4.0.0, which is vulnerable. The existing range already permits 4.0.6, so a yarn upgrade 'form-data@^4.0.0' lockfile refresh was sufficient to move the resolved version to 4.0.6 without any manifest edit.

next

next is a direct dependency pinned exactly at 14.2.10 in package.json, which falls within the vulnerable range for all listed Next.js advisories. It was bumped to 15.5.24 — the proposed target and the minimum version satisfying the highest patched floor (15.5.24) across all listed advisories. The companion package eslint-config-next, which was pinned at 13.4.13 (the same prior next version), was aligned to 15.5.24 in the same edit as required by the related-package alignment policy.

Version changes

Package	From	To	Why updated
next	14.2.10	15.5.24	Direct CVE fix
eslint-config-next	13.4.13	15.5.24	Related package alignment with next
axios	1.7.8	1.19.0	Transitive CVE fix — lockfile refresh under langfuse-node@3.31.0 (^1.7.4)
form-data	4.0.0	4.0.6	Transitive CVE fix — lockfile refresh under axios (^4.0.0)

Note

Medium Risk
Next.js 14→15 is a major upgrade with framework breaking changes; scope is limited to the example app and lockfile, but build/runtime regressions are possible until CI or manual verification passes.

Overview
This PR updates examples/example-web-nextjs dependency versions to address reported vulnerabilities in Next.js, axios, and form-data, with no changes to example app source.

package.json bumps next from 14.2.10 to 15.5.24 and aligns eslint-config-next from 13.4.13 to 15.5.24.

yarn.lock is regenerated for that upgrade. Transitive resolutions move axios to 1.19.0 (via langfuse-node) and form-data to 4.0.6, and pull in Next 15’s toolchain (e.g. sharp, newer @typescript-eslint/* and ESLint plugin versions tied to eslint-config-next 15).

Reviewers should treat this as a major Next jump for the sample app only; validate yarn build / next lint and watch for Next 15 breaking changes if the example grows beyond the current minimal App Router setup.
