Bumps [pyjwt](https://github.com/jpadilla/pyjwt) from 2.12.0 to 2.13.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/jpadilla/pyjwt/releases";>pyjwt's releases</a>.</em></p> <blockquote> <h2>2.13.0</h2> <h1>PyJWT 2.13.0 — Security Release</h1> <p>This release bundles five security fixes plus three additional hardening / spec-compliance changes. We recommend all users upgrade.</p> <h2>Security</h2> <ul> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx";><code>GHSA-xgmm-8j9v-c9wx</code></a> — JWK JSON accepted as HMAC secret (algorithm confusion).</strong> <code>HMACAlgorithm.prepare_key</code> 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 <code>algorithms=[…]</code> 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. <em>Reported by <a href="https://github.com/aradona91";><code>@aradona91</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-jq35-7prp-9v3f";><code>GHSA-jq35-7prp-9v3f</code></a> — Algorithm allow-list bypass with <code>PyJWK</code> / <code>PyJWKClient</code>.</strong> When verifying with a <code>PyJWK</code>, the caller's <code>algorithms=[…]</code> allow-list was checked against the token header <code>alg</code> as a string only; actual verification used the algorithm bound to the <code>PyJWK</code>. 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 <code>alg</code> to match the <code>PyJWK</code>'s algorithm before verification. <em>Reported by <a href="https://github.com/sushi-gif";><code>@sushi-gif</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w7vc-732c-9m39";><code>GHSA-w7vc-732c-9m39</code></a> — DoS via base64 decode of unused payload segment when <code>b64=false</code>.</strong> For detached-payload JWS (<code>b64=false</code>), the compact-form payload segment was base64-decoded before being discarded in favor of the caller-supplied <code>detached_payload</code>. 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. <em>Reported by <a href="https://github.com/thesmartshadow";><code>@thesmartshadow</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-993g-76c3-p5m4";><code>GHSA-993g-76c3-p5m4</code></a> — <code>PyJWKClient</code> accepts non-HTTP(S) URIs.</strong> <code>PyJWKClient.fetch_data</code> passed its URI to <code>urllib.request.urlopen</code>, which by default also handles <code>file://</code>, <code>ftp://</code>, and <code>data:</code> schemes. An application that fed an attacker-influenced URI into <code>PyJWKClient</code> could be coerced into reading local files or reaching other unintended schemes. <code>PyJWKClient</code> now rejects any URI whose scheme isn't <code>http</code> or <code>https</code>. <em>Reported by <a href="https://github.com/KEIJOT";><code>@KEIJOT</code></a>.</em></p> </li> <li> <p><strong><a href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-fhv5-28vv-h8m8";><code>GHSA-fhv5-28vv-h8m8</code></a> — <code>PyJWKClient</code> cache wiped on fetch error.</strong> A <code>finally</code>-block <code>put(jwk_set=None)</code> 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. <em>Reported by <a href="https://github.com/eddieran";><code>@eddieran</code></a>.</em></p> </li> </ul> <h2>Fixed</h2> <ul> <li>Reject empty HMAC keys outright in <code>HMACAlgorithm.prepare_key</code> with <code>InvalidKeyError</code> instead of accepting them with only a warning. Defends against the <code>os.getenv("JWT_SECRET", "")</code> footgun. <em>Thanks to <a href="https://github.com/SnailSploit";><code>@SnailSploit</code></a> and <a href="https://github.com/spartan8806";><code>@spartan8806</code></a> for the reports.</em></li> <li>Forward per-call <code>options</code> (including <code>enforce_minimum_key_length</code>) from <code>PyJWT.decode</code> through to <code>PyJWS._verify_signature</code>. The option was previously silently dropped between the two layers, so it only took effect when set on the <code>PyJWT</code> instance. <em>Thanks to <a href="https://github.com/WLUB";><code>@WLUB</code></a> for the report.</em></li> <li><strong>RFC 7797 §3 compliance for <code>b64=false</code>:</strong> the encoder now auto-adds <code>"b64"</code> to <code>crit</code>, and the decoder rejects tokens that set <code>b64=false</code> without listing it in <code>crit</code>. <em>Thanks to <a href="https://github.com/MachineLearning-Nerd";><code>@MachineLearning-Nerd</code></a> for the report.</em></li> </ul> <h2>Changed</h2> <ul> <li>Migrate the <code>dev</code>, <code>docs</code>, and <code>tests</code> package extras to dependency groups, by <a href="https://github.com/kurtmckee";><code>@kurtmckee</code></a> in <a href="https://redirect.github.com/jpadilla/pyjwt/pull/1152";>#1152</a>.</li> </ul> <h2>Upgrade notes</h2> <p>Most fixes are invisible to correctly-configured callers. A few behavioral changes you may encounter:</p> <ul> <li><strong>Empty HMAC keys now raise.</strong> If your app passed <code>""</code> or <code>b""</code> as a secret (often via a missing env var, e.g. <code>os.getenv("JWT_SECRET", "")</code>), <code>encode</code>/<code>decode</code> will now raise <code>InvalidKeyError</code>. This is the intended behavior — fix the configuration.</li> <li><strong><code>PyJWK</code> decoding now requires the token's <code>alg</code> to match the JWK's algorithm.</strong> Previously a mismatch was silently honored if the header <code>alg</code> appeared in the allow-list. Tokens that relied on this mismatch will now fail with <code>InvalidAlgorithmError</code>.</li> <li><strong><code>PyJWKClient</code> now rejects non-HTTP(S) URIs at construction time.</strong> Tests or dev environments that fetched JWKS from <code>file://</code> URIs need to switch to a local HTTP server or load the JWKS by other means (e.g. construct <code>PyJWKSet.from_dict(...)</code> directly).</li> <li><strong><code>b64=false</code> tokens are now strictly RFC 7515 / 7797 compliant.</strong> Tokens with a non-empty compact-form payload segment, or that omit <code>"b64"</code> from <code>crit</code>, will be rejected. PyJWT-produced tokens always satisfy both invariants, so round-trips through PyJWT are unaffected.</li> <li><strong><code>enforce_minimum_key_length</code> set per-call now takes effect.</strong> Callers who passed <code>options={"enforce_minimum_key_length": True}</code> to <code>jwt.decode()</code> previously got no enforcement; they will now get <code>InvalidKeyError</code> on undersized keys, as documented.</li> </ul> <p><strong>Full changelog:</strong> <a href="https://github.com/jpadilla/pyjwt/compare/2.12.1...2.13.0";>https://github.com/jpadilla/pyjwt/compare/2.12.1...2.13.0</a></p> <h2>2.12.1</h2> <h2>What's Changed</h2> <ul> <li>Add typing_extensions dependency for Python < 3.11 by <a href="https://github.com/jpadilla";><code>@jpadilla</code></a> in <a href="https://redirect.github.com/jpadilla/pyjwt/pull/1151";>jpadilla/pyjwt#1151</a></li> </ul> <p><strong>Full Changelog</strong>: <a href="https://github.com/jpadilla/pyjwt/compare/2.12.0...2.12.1";>https://github.com/jpadilla/pyjwt/compare/2.12.0...2.12.1</a></p> </blockquote> </details> <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/jpadilla/pyjwt/blob/master/CHANGELOG.rst";>pyjwt's changelog</a>.</em></p> <blockquote> <h2><code>v2.13.0 <https://github.com/jpadilla/pyjwt/compare/2.12.1...2.13.0></code>__</h2> <p>Security</p> <pre><code> - 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>`__. <p>Fixed</p> <pre><code> - 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``.
