pyjwt: PyJWT: Authentication bypass via acceptance of DER public keys as HMAC secrets
A flaw was found in PyJWT. The library fails to identify asymmetric public keys supplied in Distinguished Encoding Rules DER format, inadvertently treating the public data as a shared secret in Hash-based Message Authentication Code HMAC operations. If an application supports both asymmetric and...
pyjwt: PyJWT: Authentication bypass via improper public key validation
A flaw was found in PyJWT. When an application allows both symmetric and asymmetric signing algorithms, minor formatting variations in a public key can prevent the library from properly identifying it as an asymmetric key. Consequently, the library improperly treats the public key as a shared...
pyjwt: pyjwt: Verification key substitution via unvalidated JWKS redirects
A flaw was found in PyJWT. When retrieving cryptographic keys from a JSON Web Key Set JWKS endpoint, PyJWKClient fails to validate HTTP redirect destinations against trusted domain boundaries. A remote attacker who can influence the response of a trusted endpoint can redirect key requests to an...
pyjwt: pyjwt: Token forgery via improper Unicode byte-order mark handling
A flaw was found in pyjwt. When verifying cryptographic keys, the raw JSON Web Key JWK parser fails to normalize Unicode byte-order marks BOM. In mixed-algorithm verification environments, an attacker who knows the public key can supply a key prefixed with a byte-order mark, causing the system to...
