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.

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.

Updates sentence-transformers from 5.5.0 to 5.5.1

Release notes

Sourced from sentence-transformers's releases.

v5.5.1 - Small Multimodal patch

This patch release fixes a small quirk with multimodal inference when using single-key multimodal inputs like model.encode({"image": ...}).

Install this version with

# Training + Inference
pip install sentence-transformers[train]==5.5.1
Inference only, use one of:
pip install sentence-transformers==5.5.1
pip install sentence-transformers[onnx-gpu]==5.5.1
pip install sentence-transformers[onnx]==5.5.1
pip install sentence-transformers[openvino]==5.5.1
Multimodal dependencies (optional):
pip install sentence-transformers[image]==5.5.1
pip install sentence-transformers[audio]==5.5.1
pip install sentence-transformers[video]==5.5.1
Or combine as needed:
pip install sentence-transformers[train,onnx,image]==5.5.1

Bug fixed

Previously, inference like model.encode({"image": ...}) or model.encode([{"image": ...}, ...]) would be inferred as the ("image",) modality, which differed from the inferred modality of "image" for just model.encode(my_image) or model.encode([my_image, my_image_2, ...]).

This results in confusing errors if the model doesn't have a modality_config mapping for ("image",) in addition to "image", so now a single-key multimodal dict is collapsed to the bare modality (just "image" in this example).

This affected this code:

from sentence_transformers import SentenceTransformer
model = SentenceTransformer('BAAI/BGE-VL-base', trust_remote_code=True)
embedding = model.encode({"image": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/blog/ettin-reranker/mteb_ndcg10_all-MiniLM-L6-v2.png&quot;})
print(embedding.shape)

Which previously failed as the model only implements a path for "text", "image", and ("image", "text").
