<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.

— 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>

— 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>

— <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>.

— <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

<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(&quot;JWT_SECRET&quot;, &quot;&quot;)</code> footgun.

<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>&quot;b64&quot;</code> to
<code>crit</code>, and the decoder rejects tokens that set
<code>b64=false</code> without listing it in <code>crit</code>.

<li>Migrate the <code>dev</code>, <code>docs</code>, and
<code>tests</code> package extras to dependency groups, by <a

</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>&quot;&quot;</code> or <code>b&quot;&quot;</code> as a secret
(often via a missing env var, e.g.
<code>os.getenv(&quot;JWT_SECRET&quot;, &quot;&quot;)</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>&quot;b64&quot;</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={&quot;enforce_minimum_key_length&quot;: True}</code> to
<code>jwt.decode()</code> previously got no enforcement; they will now
get <code>InvalidKeyError</code> on undersized keys, as documented.</li>

<h2><code>v2.13.0

<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
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx&gt;`__.
- 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
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-jq35-7prp-9v3f&gt;`__.
- 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
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-993g-76c3-p5m4&gt;`__.
- 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
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-fhv5-28vv-h8m8&gt;`__.
- 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
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w7vc-732c-9m39&gt;`__.
<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
``&amp;quot;b64&amp;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.
