Name of the Vulnerable Software and Affected Versions Broken Link Checker WordPress plugin versions prior to 1.11.20

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 1.11.20, update to version 1.11.20 or later to resolve the issue. As a temporary workaround, consider restricting the settings that are not properly sanitized and escaped to minimize the risk of exploitation.
