Technical details
This is an unauthenticated reflected or stored cross-site scripting (XSS) vulnerability in wpDataTables plugin versions up to 6.5.1.4. The vulnerability exists due to insufficient input validation or output encoding in the plugin's code, allowing attackers to inject arbitrary JavaScript. The attack can be initiated by an unauthenticated user by crafting a malicious link or form submission, though user interaction (clicking a link or visiting a crafted page) is required for successful exploitation. An attacker can steal session cookies, perform actions on behalf of the victim, harvest credentials, or compromise site functionality. The vulnerability was patched in version 6.5.1.5.
