CVE-2022-23541

A flaw was found in the jsonwebtoken library. Affected versions of jsonwebtoken library can be misconfigured so that passing a poorly implemented key retrieval function will result in incorrect verification of tokens. Using a different algorithm and key combination in verification than what was used to sign the tokens, specifically, tokens signed with an asymmetric public key could be verified with a symmetric HS256 algorithm. This can lead to the successful validation of forged tokens.
