Updates sqlalchemy from 2.0.49 to 2.0.50

Release notes

Sourced from sqlalchemy's releases.

2.0.50

Released: May 24, 2026

orm

  • [orm] [bug] Fixed issue where using _orm.joinedload() with PropComparator.of_type() targeting a joined-table subclass combined with PropComparator.and_() referencing a column on that subclass would generate invalid SQL, where the subclass column was not adapted to the subquery alias. Pull request courtesy Joaquin Hui Gomez.

    References: #13203

  • [orm] [bug] Fixed issue where the presence of a SessionEvents.do_orm_execute() event hook would cause internal execution options such as yield_per and loader-specific state from the first orm_pre_session_exec pass to leak into the second pass, leading to errors when using relationship loaders such as selectinload() and immediateload(). The execution options passed to the second compilation pass are now based on the original options plus only the explicit updates made via ORMExecuteState.update_execution_options() within the event hook.

    References: #13301

  • [orm] [bug] Fixed issue where using _orm.with_polymorphic() on a leaf class (a subclass with no further descendants) or a non-inherited class would fail with an AttributeError when used in an ORM statement, due to _orm.configure_mappers() not being triggered implicitly. The fix ensures that AliasedInsp participates in the _post_inspect hook, triggering mapper configuration during ORM statement compilation.

    References: #13319

sql

  • [sql] [bug] Fixed issue where floor division (//) between a Float or Numeric numerator and an Integer denominator would omit the FLOOR() SQL wrapper on dialects where Dialect.div_is_floordiv is True (the default, including PostgreSQL and SQLite). FLOOR() is now applied if either the denominator or the numerator is a non-integer, so that expressions such as float_col // int_col render as FLOOR(float_col / int_col) instead of the incorrect float_col / int_col. Pull request courtesy r266-tech.

2.13.0

PyJWT 2.13.0 — Security Release

This release bundles five security fixes plus three additional hardening / spec-compliance changes. We recommend all users upgrade.

Security

  • GHSA-xgmm-8j9v-c9wx — JWK JSON accepted as HMAC secret (algorithm confusion). HMACAlgorithm.prepare_key previously rejected PEM- and SSH-formatted asymmetric keys but did not catch a JWK passed as a raw JSON string. In a verifier configured with both symmetric and asymmetric algorithms in algorithms=[…] and a raw-JSON JWK as the key, an attacker could forge HS256 tokens using the JWK text as the HMAC secret. The guard has been extended to reject any JWK-shaped JSON. Reported by @​aradona91.

  • GHSA-jq35-7prp-9v3f — Algorithm allow-list bypass with PyJWK / PyJWKClient. When verifying with a PyJWK, the caller's algorithms=[…] allow-list was checked against the token header alg as a string only; actual verification used the algorithm bound to the PyJWK. An attacker who controlled a registered JWKS key could sign with one algorithm and advertise another on the header. PyJWT now requires the token header alg to match the PyJWK's algorithm before verification. Reported by @​sushi-gif.

  • GHSA-w7vc-732c-9m39 — DoS via base64 decode of unused payload segment when b64=false. For detached-payload JWS (b64=false), the compact-form payload segment was base64-decoded before being discarded in favor of the caller-supplied detached_payload. An attacker could inflate the unused segment to force CPU + memory cost without holding a valid signature. The segment is now required to be empty per RFC 7515 Appendix F, and is no longer decoded. Reported by @​thesmartshadow.

  • GHSA-993g-76c3-p5m4 — PyJWKClient accepts non-HTTP(S) URIs. PyJWKClient.fetch_data passed its URI to urllib.request.urlopen, which by default also handles file://, ftp://, and data: schemes. An application that fed an attacker-influenced URI into PyJWKClient could be coerced into reading local files or reaching other unintended schemes. PyJWKClient now rejects any URI whose scheme isn't http or https. Reported by @​KEIJOT.

  • GHSA-fhv5-28vv-h8m8 — PyJWKClient cache wiped on fetch error. A finally-block put(jwk_set=None) cleared the JWK Set cache whenever a fetch raised, turning a transient JWKS-endpoint outage into application-wide auth failure. The cache write was moved into the success path; transient errors no longer evict valid cached keys. Reported by @​eddieran.

Fixed

  • Reject empty HMAC keys outright in HMACAlgorithm.prepare_key with InvalidKeyError instead of accepting them with only a warning. Defends against the os.getenv("JWT_SECRET", "") footgun. Thanks to @​SnailSploit and @​spartan8806 for the reports.
  • Forward per-call options (including enforce_minimum_key_length) from PyJWT.decode through to PyJWS._verify_signature. The option was previously silently dropped between the two layers, so it only took effect when set on the PyJWT instance. Thanks to @​WLUB for the report.
  • RFC 7797 §3 compliance for b64=false: the encoder now auto-adds "b64" to crit, and the decoder rejects tokens that set b64=false without listing it in crit. Thanks to @​MachineLearning-Nerd for the report.

Changed

  • Migrate the dev, docs, and tests package extras to dependency groups, by @​kurtmckee in #1152.

Upgrade notes

Most fixes are invisible to correctly-configured callers. A few behavioral changes you may encounter:

  • Empty HMAC keys now raise. If your app passed "" or b"" as a secret (often via a missing env var, e.g. os.getenv("JWT_SECRET", "")), encode/decode will now raise InvalidKeyError. This is the intended behavior — fix the configuration.
  • PyJWK decoding now requires the token's alg to match the JWK's algorithm. Previously a mismatch was silently honored if the header alg appeared in the allow-list. Tokens that relied on this mismatch will now fail with InvalidAlgorithmError.
  • PyJWKClient now rejects non-HTTP(S) URIs at construction time. Tests or dev environments that fetched JWKS from file:// URIs need to switch to a local HTTP server or load the JWKS by other means (e.g. construct PyJWKSet.from_dict(...) directly).
  • b64=false tokens are now strictly RFC 7515 / 7797 compliant. Tokens with a non-empty compact-form payload segment, or that omit "b64" from crit, will be rejected. PyJWT-produced tokens always satisfy both invariants, so round-trips through PyJWT are unaffected.
  • enforce_minimum_key_length set per-call now takes effect. Callers who passed options={"enforce_minimum_key_length": True} to jwt.decode() previously got no enforcement; they will now get InvalidKeyError on undersized keys, as documented.

Changelog

v2.13.0 <https://github.com/jpadilla/pyjwt/compare/2.12.1...2.13.0>__

Security


- Reject JWK JSON documents passed as raw HMAC secrets in
  ``HMACAlgorithm.prepare_key`` to close an algorithm-confusion gap that
  the existing PEM/SSH guard did not cover. Reported by @aradona91 in
  `GHSA-xgmm-8j9v-c9wx <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx>`__.
- Bind the JWT header ``alg`` to ``PyJWK.algorithm_name`` during
  verification so the caller's ``algorithms=[...]`` allow-list cannot be
  bypassed when decoding with a ``PyJWK`` / ``PyJWKClient`` key. Reported
  by @sushi-gif in `GHSA-jq35-7prp-9v3f <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-jq35-7prp-9v3f>`__.
- Reject non-``http(s)`` URI schemes in ``PyJWKClient`` so attacker-
  influenced URIs cannot read local files or reach unintended schemes via
  urllib's default ``file://`` / ``ftp://`` / ``data:`` handlers. Reported
  by @KEIJOT in `GHSA-993g-76c3-p5m4 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-993g-76c3-p5m4>`__.
- Preserve the cached JWK Set on fetch errors in ``PyJWKClient.fetch_data``.
  The previous ``finally``-block ``put(None)`` pattern cleared the cache
  on any transient outage, turning one bad JWKS request into application-
  wide auth failure. Reported by @eddieran in `GHSA-fhv5-28vv-h8m8 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-fhv5-28vv-h8m8>`__.
- Skip the unconditional base64 decode of the compact-form payload segment
  when ``b64=false`` is set in the protected header, and require that
  segment to be empty (RFC 7515 Appendix F detached form). Closes an
  unauthenticated DoS amplifier. Reported by @thesmartshadow in
  `GHSA-w7vc-732c-9m39 <https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w7vc-732c-9m39>`__.

Fixed



- Reject empty HMAC keys outright in ``HMACAlgorithm.prepare_key`` with
  ``InvalidKeyError`` instead of accepting them with only a warning.
  Thanks to @SnailSploit and @spartan8806 for independently flagging the
  footgun.
- Forward per-call ``options`` (including ``enforce_minimum_key_length``)
  from ``PyJWT.decode`` through to ``PyJWS._verify_signature`` so the
  option actually takes effect when set at the call site rather than only
  on the ``PyJWT`` instance. Thanks to @WLUB for the report.
- RFC 7797 §3 compliance for ``b64=false``: the encoder now auto-adds
  ``&quot;b64&quot;`` to the ``crit`` header parameter, and the decoder rejects
  tokens that set ``b64=false`` without listing it in ``crit``. Thanks to
  @MachineLearning-Nerd for the report.
