Vulnerability Details
urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP "Content-Encoding" header (e.g., "gzip", "deflate", "br", or "zstd"). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting "preload_content=False" when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when "preload_content=False". If upgrading is not immediately possible, disable redirects by setting "redirect=False" for requests to untrusted source.

Vulnerability Details
urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data.

Vulnerability Details
Impact When following cross-origin redirects for requests made using urllib3’s high-level APIs, such as "urllib3.request()", "PoolManager.request()", and "ProxyManager.request()", sensitive headers — "Authorization", "Cookie", and "Proxy-Authorization" (defined in "Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT") — are stripped by default, as expected. However, cross-origin redirects followed from the low-level API via "ProxyManager.connection_from_url().urlopen(..., assert_same_host=False)" still forward these sensitive headers. Affected usage Applications and libraries using urllib3 versions earlier than 2.7.0 may be affected if they allow cross-origin redirects while making requests through "HTTPConnection.urlopen()" instances created via "ProxyManager.connection_from_url()". Remediation Upgrade to urllib3 version 2.7.0 or later, in which sensitive headers are stripped from redirects followed by "HTTPConnection". If upgrading is not immediately possible, avoid using this low-level redirect flow for cross-origin redirects. If appropriate for your use case, switch to "ProxyManager.request()".

Vulnerability Details
Requests is a HTTP library. Prior to version 2.33.0, the "requests.utils.extract_zipped_paths()" utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call "extract_zipped_paths()" directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set "TMPDIR" in their environment to a directory with restricted write access.
