    CVE-2026-64623

    Network-AI before 5.13.4 contains an improper cryptographic signature verification vulnerability in APSAdapter where the default local verifier accepts any non-empty string as valid. Unauthenticated attackers can submit forged APS delegation payloads with arbitrary scopes to bypass signature verification and obtain signed permission-grant tokens for sensitive resources including SHELL_EXEC.
