Technical details
The plugin fails to properly sanitize user input during web page generation, allowing stored XSS injection. Exploitation requires a user with contributor or developer privilege to craft and submit malicious input, which is then stored and executed in the browsers of other site visitors. This grants attackers the ability to steal session tokens, credentials, or perform actions as affected users.
