What is CVE-2025-15708?
The Live Composer WordPress plugin prior to version 2.1.23 lacks proper sanitization and escaping for its custom post type slug settings. This flaw can enable high privilege users, such as administrators, to execute Stored Cross-Site Scripting attacks, even in environments where the unfiltered_html capability is restricted, such as multisite configurations. Addressing this issue is crucial for protecting sites from potential exploitation.
