What is CVE-2023-46943?

A vulnerability exists in the @evershop/evershop package where the HMAC secret used for generating tokens is hardcoded to 'secret'. This predictable hardcoded value presents a significant security risk, as malicious actors may exploit it to forge valid JSON Web Tokens (JWTs). These tokens could grant unauthorized access to sensitive information and application functionalities, potentially leading to serious breaches. Ensuring the use of strong, non-predictable HMAC secrets is critical to maintaining application integrity and security.
