What is CVE-2026-77009?

The WatchMan-Site7 WordPress plugin, prior to version 4.2.0, fails to adequately restrict access to its debugging console. This oversight permits any authenticated user, including those with minimal roles such as subscriber, to execute arbitrary PHP code on the server. Such vulnerabilities can lead to significant security risks, allowing malicious actors to compromise the integrity and confidentiality of the affected WordPress site.

Affected Version(s)

WatchMan-Site7 3.1.1 <= 4.2.0

Exploit Proof of Concept (PoC)
