CVE-2026-31915Network attack vector

Unauthenticated unauthorized action via missing capability check

Published Mar 13, 2026 · Updated Mar 13, 2026

Missing authorization in UX Themes Flatsome 3.19.6 and earlier allows remote attackers to perform an unauthorized action. An unnamed theme function executes the requested action without a WordPress capability check; public records do not identify the function, request parameter, or protected operation. No authentication or user interaction is required, and published assessments conflict on whether the consequence is unauthorized data access or modification.
