→Monitor HTTP GET requests to the plugin's download.php endpoint containing 'download_file=' parameter with path traversal sequences (e.g., '..././') — unauthenticated access to this endpoint is the exploit vector. ↗
→Alert on requests to download.php that return HTTP 200 without any session/authentication cookie, as the plugin performs no login or privilege check. ↗
→Detect the obfuscated path traversal pattern '..././' (dot-dot-slash with embedded dot) used to bypass naive traversal filters when targeting wp-config.php or /etc/passwd. ↗

·The vulnerability only affects version 1.58 of the plugin; sites running a patched or updated version are not affected. ↗
