WordPress Plugin Vulnerabilities
Broken Link Checker < 1.11.20 - Admin+ Cross-Site Scripting
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
Proof of Concept
Put the following payload in the Youtube API Key settings and save: test"><script>alert(/XSS/)</script>. The XSS will be triggered when viewing the settings page again
