Name of the Vulnerable Software and Affected Versions Network-AI versions prior to 5.13.4

Description An improper cryptographic signature verification issue exists in the APSAdapter component. The default local verifier incorrectly accepts any non-empty string as a valid signature. This allows unauthenticated attackers to submit forged APS delegation payloads with arbitrary scopes, bypassing signature verification to obtain signed permission-grant tokens for sensitive resources, such as SHELL EXEC.

Recommendations Update Network-AI to version 5.13.4 or later.
