Executive brief
WP Umbrella is a WordPress plugin that helps manage and monitor WordPress sites. A cross-site request forgery (CSRF) vulnerability allows attackers to trick authenticated users into performing unintended actions, such as changing settings or configuration, without their knowledge by visiting a malicious webpage.
Technical details
The vulnerability is a cross-site request forgery (CSRF) flaw in WP Umbrella affecting versions 2.24.2 through 2.26.2. The plugin fails to implement proper CSRF token validation on sensitive actions, allowing an attacker to craft a malicious page that, when visited by a logged-in administrator or privileged user, can trigger administrative functions without explicit consent. Exploitation requires user interaction (the victim must visit the attacker's page while logged in to WordPress). The vulnerability was patched in version 2.27.0.
