+Subject: [PATCH] Bundle security fixes and hardening into 2.13.0
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Security:
+- `HMACAlgorithm.prepare_key` rejects JWK JSON documents passed as raw
+  HMAC secrets to close an algorithm-confusion gap not covered by the
+  existing PEM/SSH guard. Reported by @aradona91 in 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.
+- Skip the unconditional base64 decode of the compact-form payload
+  segment when `b64=false` is set, 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.
+- `PyJWKClient` rejects any URI whose scheme is not `http` or `https` 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.
+- 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. Reported by @eddieran in GHSA-fhv5-28vv-h8m8.
+
+Fixes:
+- Reject empty HMAC keys outright in `HMACAlgorithm.prepare_key` with
+  `InvalidKeyError` instead of accepting them with only a warning.
+  Hardening prompted by reports from @SnailSploit and @spartan8806.
+- Forward per-call `options` (including `enforce_minimum_key_length`)
+  from `PyJWT.decode` through to `PyJWS._verify_signature`. Thanks to
+  @WLUB.
+- RFC 7797 §3 compliance for `b64=false`: encoder auto-adds `"b64"` to
+  `crit`; decoder rejects tokens that set `b64=false` without listing
+  it in `crit`. Thanks to @MachineLearning-Nerd.
+
+CVE: CVE-2026-48526
+Upstream-Status: Backport [https://github.com/jpadilla/pyjwt/commit/95791b1759b8aa4f2203575d344d5c78564cdc81]
+
+Backport Changes:
+- Split out the raw JWK-as-HMAC-secret rejection because the upstream
+  commit bundles multiple CVEs.
+- Omitted CHANGELOG.rst because it conflicted and is release documentation.
+- Carried `test_hmac_prepare_key_rejects_jwk_json` and
+  `test_hmac_prepare_key_accepts_json_without_kty` regression tests covering
+  the same JWK-classification security boundary.
+- Omitted other tests/test_algorithms.py hunks for separate empty-key and
+  per-call key-length hardening.
+- Omitted the 2.13.0 version bump and other bundled fixes; applicable CVE
+  fixes are carried in separate patches.
+
+(cherry picked from commit 95791b1759b8aa4f2203575d344d5c78564cdc81)
