CVE-2025-0818Network attack vector

Arbitrary file deletion via unrooted shutdown cleanup

Published Aug 13, 2025 · Updated Apr 8, 2026

Path traversal in elFinder 2.1.64 and earlier in three WordPress file-manager plugins allows remote attackers to delete arbitrary files. The onShutdown cleanup routine deletes attacker-influenced entries from its global temporary-file list without first anchoring each path beneath elFinder's temporary directory. Exploitation is unauthenticated only when a site owner explicitly exposes a file-manager instance to users, and deletion is limited to files writable by the web process.
