From 2.11.0 through 2.13.0, PyJWT&#39;s PyJWT._merge_options() method can modify a caller-supplied mutable options mapping when verify_signature is false. If an application reuses that same mapping for a later decode() or decode_complete() call and changes verify_signature to true, the mapping can retain false values for expiration, not-before, issued-at, audience, issuer, subject, and JWT ID checks. A signed token with invalid registered claims can then be accepted without disabling signature verification, but applications that create a fresh options mapping for each call are not affected.</p> <p><strong>Affected:</strong> jpadilla pyjwt</p> <p>PyJWT is a Python implementation of JSON Web Token standards.
