Summary PyJWKClient.get signing key from jwttoken — the first step of the JWKS verification flow documented in docs/usage.rst — must decode a token's payload before its signature can be checked, via jwt.api jwt.decode completetoken, options="verify signature": False. That call parses the payload...

Summary PyJWT 2.13.0 accepts compact JWS signature segments containing characters that are not in the Base64URL alphabet. Appending !!!! to a valid signature does not change the decoded signature bytes or authenticated claims, but it changes the serialized token and its SHA-256 hash. An applicati...

Summary PyJWT 2.13.0 PyJWKClient followed HTTP redirects while fetching a JWKS, without validating the redirect destination. A configured trusted endpoint could therefore redirect the client to a different host. Impact When an application uses PyJWKClient with caller-supplied request headers and ...

Summary PyJWT.decode/decode complete mutates a caller-supplied options dict in place whenever verify signature is falsy, adding verify exp/verify nbf/verify iat/verify aud/verify iss/verify sub/verify jti keys directly onto that object. If application code reuses the same options dict across call...

Summary A malformed RSA JWK inside a JWK Set aborts parsing of the entire set instead of being skipped, because RSAAlgorithm.from jwk can raise a plain ValueError that isn't caught by PyJWKSet's per-key error-skipping logic.
