• fix(security): sandbox MaltParser's Java execution (CVE-2026-12252, CVE-2026-12841)
• fix(security): trust the system temp dir only when it is private (CWE-377/CWE-378)
• fix(security): validate corpus-reader roots against the data sandbox (CWE-73)
• fix(security): validate per-call java() options and replace the -XX:/-D allowlist with a minimal one (CWE-88)
• Additional security hardening (CWE-407, CWE-426, CWE-427, CWE-502, CWE-59, CWE-776, CWE-918)

Updates mypy from 2.3.0 to 2.3.1

Changelog

Sourced from mypy's changelog.

Mypy 2.3.1

• Fix mypyc crash on double yielding Iterators (Daniël van Noord, PR 21826)
• Fix mypyc default_factory for inherited dataclass (Daniël van Noord, PR 21785)
• Clear mypyc coroutine env on coroutine completion (Piotr Sawicki, PR 21734)
• Fix crash when unpacking return value from overload (Shantanu, PR 21830)

Acknowledgements

Thanks to all mypy contributors who contributed to this release:

• Agriya Khetarpal
• Ethan Sarp
• Ivan Levkivskyi
• Jingchen Ye
• Jukka Lehtosalo
• Piotr Sawicki
• Shantanu

I'd also like to thank my employer, Dropbox, for supporting mypy development.

Mypy 2.2

We've just uploaded mypy 2.2.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>
