Key confusion through non-blocklisted public key formats in PyJWT

...

Authentication Bypass

pyjwt is vulnerable to authentication bypass. The vulnerability exists because the library permits an attacker submitting a JWT token to choose which algorithms are used when signing in, enabling non-blocklisted, but weak public key formats to be supported in the authentication process allowing a...

PyJWT vulnerable to key confusion attacks

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...
