CVE-2026-75133Network attack vectorHinoki check available

Database disclosure via unauthenticated backup trigger

Published Aug 31, 2026 · Updated Aug 31, 2026

Missing authentication in Keep Backup Daily before 2.1.4 allows remote attackers to trigger and retrieve a full MySQL database dump. The public kbd_cron_process parameter invokes the backup routine without an identity check and stores the dump under a filename derived from the database name, a small random range, and the current Unix timestamp. No account or user interaction is required; successful prediction exposes the complete database through the public uploads directory.
