CVE-2026-25510Public exploitNetwork attack vector

Authenticated code execution via unrestricted PHP file creation

Published Feb 3, 2026 · Updated Feb 3, 2026

Code injection in CI4MS before 0.28.5.0 allows remote authenticated users to execute arbitrary server-side PHP code. The createFile endpoint accepts executable extensions in web-accessible paths, while saveFile writes attacker-supplied content without type validation. File-editor permission is required; a resulting PHP webshell executes OS commands with the web server process's privileges.
