CVE-2023-4637Network attack vector

Path disclosure via missing restore authorization

Published Feb 5, 2024 · Updated Apr 8, 2026

Missing authorization in WPvivid — Backup, Migration & Staging 0.9.94 and earlier allows remote attackers to disclose full file paths. The restore() and get_restore_progress() handlers accept a backup ID without first enforcing a WordPress capability check. A valid backup ID is required; the reported consequence is disclosure of full server file paths, not backup contents or modification.
