Token-gated log placement via path traversal
Published Aug 16, 2026 · Updated Aug 16, 2026
Path traversal in WPvivid — Backup, Migration & Staging before 0.9.131 allows remote attackers to place fixed-content log files. The send_to_site_connect handler uses an unsanitized backup_id from an encrypted request to construct the transfer log path. A live site-to-site transfer key is required; the attacker controls only the destination directory, not the suffixed filename or log-header content.
