Name of the Vulnerable Software and Affected Versions Cookie Bar WordPress plugin versions prior to 1.8.9

Description The issue is related to the improper sanitization of the Cookie Bar Message setting, which could allow high-privilege users to perform Cross-Site Scripting attacks. This is possible even when the unfiltered html capability is disallowed.

Recommendations For versions prior to 1.8.9, update to version 1.8.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the Cookie Bar Message setting to minimize the risk of exploitation.
