The WPMK PDF Generator plugin suffers from a CSRF vulnerability that enables stored XSS attacks. This affects versions up to 1.0.1, allowing attackers to trick authenticated users into executing unwanted actions that result in malicious scripts being stored and potentially executed in the context of the victim's browser. The CVSS 3.1 score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation can lead to stored XSS, which may allow attackers to execute arbitrary scripts in the context of affected users, potentially leading to data theft, session hijacking, or other malicious activities. The vulnerability requires user interaction but no privileges, and it can be exploited remotely over the network.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should consider disabling the plugin or restricting access to trusted users only. Monitor official WPMK channels for updates and patches addressing this vulnerability.
