CVE-2026-16253Network attack vector

Unauthenticated disclosure and forced restore via exposed secret

Published Aug 12, 2026 · Updated Aug 12, 2026

Information exposure in BoldGrid Total Upkeep before 1.17.3 allows remote attackers to read backup details and force a full site restore. Emergency-restore metadata exposes the cron_secret that authorizes restoration because an earlier protection never took effect in distributed plugin copies. Unauthenticated network access is sufficient; a forced restore overwrites the live site's files and database with backup contents.
