Description

WordPress Plugin Relevanssi-A Better Search is prone to an HTML injection vulnerability because it fails to properly sanitize user-supplied input. Attacker-supplied HTML and script code could be executed in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible. WordPress Plugin Relevanssi-A Better Search version 2.7.2 is vulnerable; other versions may also be affected.
