Until an official fix is available, users should consider disabling the Excerpt Highlights feature or applying custom input sanitization and output escaping as a temporary mitigation. Monitor official Relevanssi communications for updates and apply patches promptly once released.
Description
The Relevanssi – A Better Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Excerpt Highlights in all versions up to, and including, 4.24.5 (Free) and 2.27.6 (Premium) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
