CVE-2024-9290Network attack vector

Published Dec 13, 2024 · Updated Apr 8, 2026

Unrestricted file upload in azzaroco WP SuperBackup 2.3.3 and earlier allows remote attackers to place arbitrary files on the server. The ibk_restore_migrate_check() handler accepts migration uploads without checking file type or verifying the caller's capability. No account is required; code execution follows when the web server processes an uploaded executable file.
