python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens
A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

Origin Validation Error
Overview Affected versions of this package are vulnerable to Origin Validation Error in the OIDC discovery process when the X-Forwarded-Host header is not validated and no allowed-hosts list is configured. An attacker can manipulate the issuer and JWKS URI in the discovery document by supplying a...
CVE-2026-59096
