WordPress · Usm-Premium · CVE-2023-1166
**Name of the Vulnerable Software and Affected Versions**
USM-Premium WordPress plugin versions prior to 16.3
**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 multisite setups. This is due to the plugin not sanitizing and escaping some of its settings.
**Recommendations**
For versions prior to 16.3, update to version 16.3 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.
