AI-suggested
This vulnerability is addressed in Cocos AI version 0.9.0. Users should upgrade to version 0.9.0 or later to mitigate this issue. However, because the vulnerability arises from the confidential computing threat model itself, it cannot be fully mitigated by source code changes alone. Additional architectural or operational controls may be necessary to manage risk.
Description
CVE-2026-119344 is a critical origin validation error in the Cocos AI confidential computing system versions 0.8.2 and earlier. The vulnerability allows a remote attacker controlling another trusted platform to substitute valid attestation Evidence, causing authorization of an incorrect platform. This flaw arises because the system accepts attestation Evidence without binding it to a unique platform owner or enforcing revocation. The issue is addressed in version 0.9.0, but cannot be fully mitigated by source code changes alone due to the underlying confidential computing threat model.
