Mitigation Strategies

Immediate mitigation involves applying the mitigation rule issued by Patchstack to block attacks targeting this vulnerability until an official patch is released.

Since no official patch is currently available, it is advised to implement security measures such as enabling a web application firewall (WAF) with rules to detect and block reflected XSS attempts.

Additionally, monitoring and restricting user input, avoiding clicking on suspicious links, and limiting privileged user interactions with untrusted content can reduce the risk of exploitation.
