Technical details
The vulnerability is a cross-site request forgery (CSRF) flaw in RTMKit versions <= 2.1.5 that affects subscribers. CSRF attacks exploit the trust a web application places in authenticated user requests by injecting malicious requests into pages the user visits. Successful exploitation requires a subscriber-level user to interact with a crafted malicious link or page. An attacker can trick the user into performing unintended actions within the plugin without their explicit consent. The vulnerability has been patched in version 2.1.6 and later.
