What is CVE-2026-14714?

A vulnerability affecting zhayujie chatgpt-on-wechat CowAgent version 2.1.0 has been identified due to a missing authentication mechanism in the verify_server function of the wx Endpoint component.

To mitigate this issue, users are strongly advised to upgrade to version 2.1.1, which incorporates a security check ensuring that empty or default token values result in a 403 Forbidden response, thereby enhancing the integrity of server interactions.
