CVE-2025-15708 Live Composer < 2.1.23 - Admin+ Stored XSS via Partner Slug
Description
The Live Composer WordPress plugin before 2.1.23 does not sanitise and escape some of its custom post type slug settings before using them in front-end links, 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 a multisite setup).
