CVE-2023-46943 : Security Advisory and Response
Learn about CVE-2023-46943, an issue in @evershop/evershop package allowing attackers to create valid JSON Web Tokens using a hardcoded HMAC secret, enabling unauthorized access.
An issue was discovered in NPM's package @evershop/evershop before version 1.0.0-rc.8 where the HMAC secret used for generating tokens is hardcoded as "secret". This weakness allows attackers to create valid JSON Web Tokens (JWTs) using the predictable secret, granting them unauthorized access to critical information and functionalities.
