CVE-2021-24587

Name of the Vulnerable Software and Affected Versions Splash Header WordPress plugin versions prior to 1.20.8

Description The issue is related to an authenticated Stored Cross-Site Scripting problem. It occurs because the plugin does not properly sanitise and escape some of its settings when outputting them in the admin dashboard.

Recommendations For versions prior to 1.20.8, update to version 1.20.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin dashboard to minimize the risk of exploitation.
