CVE-2026-1056CRITICAL 9.8

The Snow Monkey Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'generate_user_dirpath' function in all versions up to, and including, 12.0.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

CVE-2025-14301CRITICAL 9.8

The Integration Opvius AI for WooCommerce plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.0. This is due to the `process_table_bulk_actions()` function processing user-supplied file paths without authentication checks, nonce verification, or path validation. This makes it possible for unauthenticated attackers to delete or download arbitrary files on the server via the `wsaw-log[]` POST parameter, which can be leveraged to delete critical files like `wp-config.php` or read sensitive configuration files.
