Until a fix is available, users should avoid clicking on untrusted links that might exploit this vulnerability. Monitoring vendor channels for updates and applying official patches once released is recommended.
Description
The Seraphinite Accelerator WordPress plugin contains a reflected cross-site scripting (XSS) vulnerability via the 'seraph_accel_prep' parameter in versions up to and including 2.29.15. This occurs because of improper input handling and insufficient output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when a user interacts with a crafted link.
