Users should verify if a vendor advisory or update is available for Relevanssi – A Better Search plugin beyond version 4.28.5. Until a fix is released, it is recommended to disable comment indexing and comment highlighting features to prevent exploitation of this vulnerability.

Description

The Relevanssi – A Better Search WordPress plugin is vulnerable to a stored cross-site scripting (XSS) flaw via the 'comment' parameter in versions up to and including 4.28.5. This vulnerability allows unauthenticated attackers to inject malicious scripts that execute when users visit a page accessed through a Relevanssi search-result permalink with the highlight query parameter. The exploit requires both comment indexing and comment highlighting features to be enabled.
