Summary

Improper signature verification vulnerability in auth0/node-jws versions 3.2.2 and earlier and 4.0.0. The jws.createVerify() function for HMAC algorithms may use user-provided data from the JWS protected header or payload in HMAC secret lookup routines, allowing attackers to bypass signature verification.

Risk Assessment

Attackers can forge JWS signatures, potentially leading to unauthorized access to systems using this library for authentication.

Recommendation

Update auth0/node-jws to version 3.2.3 or 4.0.1.

Original NVD description (English source)

auth0/node-jws is a JSON Web Signature implementation for Node.js. In versions 3.2.2 and earlier and version 4.0.0, auth0/node-jws has an improper signature verification vulnerability when using the HS256 algorithm under specific conditions. Applications are affected when they use the jws.createVerify() function for HMAC algorithms and use user-provided data from the JSON Web Signature protected header or payload in HMAC secret lookup routines, which can allow attackers to bypass signature verification. This issue has been patched in versions 3.2.3 and 4.0.1.
