CyberRota Analysis

AI-Generated

ZITADEL's external JWT Identity Provider prior to versions 3.4.12 and 4.15.2 is vulnerable due to improper validation of the audience (aud) claim in JWT tokens, which could allow attackers to exploit valid tokens from trusted issuers for unauthorized access. This could lead to unauthorized actions within the identity management platform, potentially compromising user data and security. Organizations using affected versions should prioritize upgrading to the latest releases to mitigate this risk.

Original NVD Description

ZITADEL is an open source identity management platform. Prior to 3.4.12 and 4.15.2, ZITADEL's external JWT Identity Provider validates a token's signature and issuer (iss) but not the audience (aud) claim, allowing a validly signed token from a trusted issuer for another relying party to be accepted by ZITADEL. This issue is fixed in versions 3.4.12 and 4.15.2.
