Authenticated arbitrary file deletion via directory traversal
Published Apr 17, 2024 · Updated Apr 28, 2026
Missing authorization in JVM Rich Text Icons 1.2.6 and earlier allows remote authenticated users to delete arbitrary server files. The delete-icon AJAX handler passes an unsanitized filename into its deletion path, permitting directory traversal beyond the icon set. Subscriber-level access is sufficient, and deletion of WordPress or server files can interrupt the site.
