External Media Project Security Vulnerabilities

CVE-2021-24311

CVE-2022-3832

The External Media WordPress plugin before 1.0.36 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).
