CVE-2022-47926Network attack vector

Unauthenticated arbitrary file deletion

Published Dec 22, 2022 · Updated Apr 15, 2025

Arbitrary file deletion in AyaCMS 3.1.2 allows remote attackers to delete files through the fst_del.inc.php administrative endpoint. The public record does not disclose which request parameter supplies the path or how fst_del.inc.php validates and passes that input to deletion logic. Attack requires network reachability but no authentication or user interaction; successful requests can remove files accessible to the web application.
