Easy PHP Settings <= 1.0.4 — Authenticated (Administrator+) PHP Code Injection via 'wp_memory_limit' Setting

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Easy PHP Settings.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 1.0.5, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Easy PHP Settings to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to ZAST.AI.

The Easy PHP Settings plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 1.0.4 via the `update_wp_memory_constants()` method. This is due to insufficient input validation on the `wp_memory_limit` and `wp_max_memory_limit` settings before writing them to `wp-config.php`. The `sanitize_text_field()` function used for sanitization does not filter single quotes, allowing an attacker to break out of the string context in a PHP `define()` statement. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject and execute arbitrary PHP code on the server by modifying `wp-config.php`, which is loaded on every page request.
