CVE-2025-13786Public exploitNetwork attack vector

Remote code execution via PHP content injection

Published Nov 30, 2025 · Updated Dec 1, 2025

Code injection in taosir WTCMS 1.0 allows remote attackers to execute arbitrary PHP code through a crafted frontend request. The unauthenticated /index.php fetch action treats the content query parameter as PHP source, allowing its payload to create a web-accessible PHP file. Requesting that file executes attacker-selected commands with the privileges of the web server process.
