The Martin WP Compare Tables plugin for WordPress, versions up to 1.0.5, contains a CSRF vulnerability that can be exploited to inject stored XSS payloads. This occurs because the plugin does not adequately verify the origin of requests, allowing attackers to trick authenticated users into submitting malicious requests. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation can lead to stored XSS, which may allow attackers to execute arbitrary scripts in the context of the victim's browser. This can result in session hijacking, defacement, or other malicious actions within the affected WordPress site. The vulnerability requires user interaction and affects confidentiality, integrity, and availability to a limited extent.

Patch status is not yet confirmed — no official fix or patch links are provided. Users of the Martin WP Compare Tables plugin should monitor the vendor's official channels for updates and apply any forthcoming patches promptly. Until a fix is available, consider disabling or removing the plugin to mitigate risk.
