The issue is not that big as 'algorithms=jwt.algorithms.get_default_algorithms()' has to be used. As a workaround, always be explicit with the algorithms that are accepted and expected when decoding.
PyJWT	1.7.1	<2.12.0	show Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity. The library does not validate the `crit` (Critical) Header Parameter as required by RFC 7515 §4.1.11 — when a JWT contains a `crit` array listing extensions that the library does not understand, the token is accepted instead of rejected. An attacker can exploit this vulnerability by crafting JWTs with unknown critical extensions (e.g., MFA requirements, token binding, scope restrictions) that are silently ignored, potentially bypassing security policies or causing split-brain verification in mixed-library deployments where other RFC-compliant libraries would reject the same token.
