CVE-2026-29014 is an unauthenticated remote code execution vulnerability in MetInfo CMS versions 7.9, 8.0, and 8.1. The flaw resides in the weixinreply::wxAdminLogin() method in the WeChat integration component, where attacker-controlled EventKey and FromUserName values from Weixin API requests are insufficiently sanitized before being used in cache::get() and cache::put() operations. The EventKey-controlled value can be abused for path traversal and arbitrary cache file inclusion, allowing manipulation of the execution flow so that attacker-controlled data is written into a PHP cache file. Because the cache-writing logic embeds non-array input inside generated PHP code, an attacker can inject arbitrary PHP using crafted input and obtain code execution without authentication. On affected deployments this results in direct execution of attacker-supplied PHP on the server.
