AI-suggested
Upgrade PixelYourSite to version 11.4.3 or later and PixelYourSite Pro to version 12.6.8 or later. These versions include fixes that properly sanitize and escape cookie values before outputting them, eliminating the XSS vulnerability. No other mitigation is indicated by the vendor advisory.
Description
A Cross-Site Scripting (XSS) vulnerability exists in the PixelYourSite WordPress plugin versions before 11.4.3 and PixelYourSite Pro versions before 12.6.8. The flaw arises because the plugins do not sanitize and escape a cookie value before outputting it on the page. On sites using full-page caching, this allows unauthenticated attackers to inject malicious scripts into the cached page, which are then served to other visitors.
