CVE-2026-102269

A flaw was found in PyJWT. When decoding JSON Web Token JWT signature segments, the library accepts characters outside the standard Base64URL encoding format. A remote attacker can exploit this issue by appending extra characters to a valid token signature, creating an alternate token...

Incorrect Behavior Order: Validate Before Canonicalize

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Incorrect Behavior Order: Validate Before Canonicalize via the load method in jwt/apijws.py, which accepts non-canonical base64url-encoded JWS segments. Because the library does not verify...
