CVE-2025-70831Public exploitNetwork attack vector

Unauthenticated code execution via mediaId shell injection

Published Feb 20, 2026 · Updated Feb 20, 2026

OS command injection in Smanga 3.2.7 allows remote attackers to execute arbitrary commands through the rescan.php mediaId parameter. The endpoint concatenates the untrusted mediaId value into a system shell command without quoting, escaping, or validation. No authentication is required, and injected shell metacharacters execute commands with the privileges of the Smanga server process.
