Hermes versions up to 0.4.0 improperly validated the JWT provided when using the AWS ALB authentication mode, potentially allowing for authentication bypass. This vulnerability, CVE-2025-1293, was fixed in Hermes 0.5.0.
Weakness
The product uses an authentication mechanism to restrict access to specific users or identities, but the mechanism does not sufficiently prove that the claimed identity is correct.

Extended Description
