Name of the Vulnerable Software and Affected Versions The Perfect Survey WordPress plugin versions 1.5.2 and earlier

Description The issue arises from the lack of validation and escaping of the X-Forwarded-For header value before it is outputted in the statistic page. This occurs when the Anonymize IP setting of a survey is turned off, leading to a Stored Cross-Site Scripting issue.

Recommendations For versions 1.5.2 and earlier, update to a version that properly validates and escapes the X-Forwarded-For header value to prevent Stored Cross-Site Scripting. As a temporary workaround, consider turning on the Anonymize IP setting for all surveys until a patch is available.
