Strategic Overview
<= 1.17.7CVE-2026-57321Vulnerability Overview
The Interactive Content – H5P plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in all versions up to, and including, 1.17.7. This makes it possible for authenticated attackers, with Contributor-level access and above, 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).
