CVE-2026-15382Public exploitNetwork attack vector

Unauthenticated font deletion via unchecked delete-bsf-fonts

Published Jul 30, 2026 · Updated Jul 30, 2026

File deletion in Ultimate Addons for WPBakery Page Builder before 3.21.4 allows remote attackers to delete custom icon font packs. The delete-bsf-fonts code path accepts an unauthenticated GET parameter without a capability or nonce check, recursively removes the uploaded font directory, and resets the smile_fonts option. Exploitation requires WPBakery Page Builder to be active and at least one administrator-uploaded custom font pack; one request removes every such pack and breaks icons that use them.
