WordPress · Modern Events Calendar Lite · CVE-2023-1400
**Name of the Vulnerable Software and Affected Versions**
The Modern Events Calendar Lite WordPress plugin versions prior to 6.5.2
**Description**
The issue allows high privilege users, such as admins, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in a multisite setup. This is due to the plugin not sanitizing and escaping some of its settings.
**Recommendations**
For versions prior to 6.5.2, update to version 6.5.2 or later to resolve the issue. As a temporary workaround, consider restricting the ability of high privilege users to access and modify the plugin's settings until a patch is applied.
