What is CVE-2026-64623?

An improper cryptographic signature verification vulnerability exists in the APSAdapter component of Network-AI versions prior to 5.13.4. Due to this flaw, the default local verifier incorrectly accepts any non-empty string as a valid input. This allows unauthenticated attackers to submit forged APS delegation payloads, effectively bypassing signature verification and gaining unauthorized access to sensitive resources, including SHELL_EXEC, through signed permission-grant tokens.

Affected Version(s)

Network-AI 0 < 5.13.4

Network-AI 5.13.4
