CVE-2026-77009: WatchMan‑Site7 plugin lets logged‑in users run code on server

CVE-2026-77009 · published 1 day ago
Summary

The WatchMan‑Site7 add‑on for WordPress (versions 3.1.1 through 4.2.0) leaves its debug console open to anyone with a basic account. That means a regular user can enter code that the server will execute, potentially giving them control of the site. Update the plugin to a new version or remove it if you don’t need the debugging feature, and restrict access to trusted administrators only.

What to do
