Summary

CVE-2026-14714 affects the verify_server function in channel/wechatmp/common.py of zhayujie chatgpt-on-wechat CowAgent 2.1.0, within the wx Endpoint. Manipulating the wechatmp_token argument causes missing authentication, and the attack can be launched remotely. A public exploit exists.

Mitigation

Upgrade to version 2.1.1 (patch 3d7c68bac6ee74fad63f43cf99e45c62e202ed55). The project added an explicit non-empty check for wechatmp_token in verify_server(), so the /wx endpoint now returns 403 Forbidden when the token is missing or left at the default empty value.
