Notes
Title of the patch: Security update for python-PyJWT
Description of the patch: This update for python-PyJWT fixes the following issue: Update to PyJWT 2.12.1: - CVE-2026-32597: PyJWT accepts unknown `crit` header extensions (bsc#1259616). Changelog: Update to 2.12.1: - Add missing typing_extensions dependency for Python < 3.11 in #1150 Update to 2.12.0: - Annotate PyJWKSet.keys for pyright by @tamird in #1134 - Close HTTPError response to prevent ResourceWarning on Python 3.14 by @veeceey in #1133 - Do not keep algorithms dict in PyJWK instances by @akx in #1143 - Use PyJWK algorithm when encoding without explicit algorithm in #1148 - Docs: Add PyJWKClient API reference and document the two-tier caching system (JWK Set cache and signing key LRU cache). Update to 2.11.0: - Enforce ECDSA curve validation per RFC 7518 Section 3.4. - Fix build system warnings by @kurtmckee in #1105 - Validate key against allowed types for Algorithm family in #964 - Add iterator for JWKSet in #1041 - Validate iss claim is a string during encoding and decoding by @pachewise in #1040 - Improve typing/logic for options in decode, decode_complete by @pachewise in #1045 - Declare float supported type for lifespan and timeout by @nikitagashkov in #1068 - Fix SyntaxWarnings/DeprecationWarnings caused by invalid escape sequences by @kurtmckee in #1103 - Development: Build a shared wheel once to speed up test suite setup times by @kurtmckee in #1114 - Development: Test type annotations across all supported Python versions, increase the strictness of the type checking, and remove the mypy pre-commit hook by @kurtmckee in #1112 - Support Python 3.14, and test against PyPy 3.10 and 3.11 by @kurtmckee in #1104 - Development: Migrate to build to test package building in CI by @kurtmckee in #1108 - Development: Improve coverage config and eliminate unused test suite code by @kurtmckee in #1115 - Docs: Standardize CHANGELOG links to PRs by @kurtmckee in #1110 - Docs: Fix Read the Docs builds by @kurtmckee in #1111 - Docs: Add example of using leeway with nbf by @djw8605 in #1034 - Docs: Refactored docs with autodoc; added PyJWS and jwt.algorithms docs by @pachewise in #1045 - Docs: Documentation improvements for "sub" and "jti" claims by @cleder in #1088 - Development: Add pyupgrade as a pre-commit hook by @kurtmckee in #1109 - Add minimum key length validation for HMAC and RSA keys (CWE-326). Warns by default via InsecureKeyLengthWarning when keys are below minimum recommended lengths per RFC 7518 Section 3.2 (HMAC) and NIST SP 800-131A (RSA). Pass enforce_minimum_key_length=True in options to PyJWT or PyJWS to raise InvalidKeyError instead. - Refactor PyJWT to own an internal PyJWS instance instead of calling global api_jws functions.
