Name of the Vulnerable Software and Affected Versions amr ical events lists WordPress plugin versions prior to 6.7

Description The issue concerns the amr ical events lists WordPress plugin, which does not properly sanitise and escape some of its settings. This could allow high-privilege users, such as administrators, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in a multisite setup.

Recommendations For versions prior to 6.7, update to version 6.7 or later to resolve the issue. As a temporary workaround, consider restricting the use of the plugin's settings to minimize the risk of exploitation.
