CVE-2026-77006: Unknown Webtotem Backups

Critical severity, CVSS 9.6. EPSS: 0.2% chance of exploitation in the next 30 days.

The WebTotem Backups WordPress plugin before 1.1.0 does not validate a user-supplied file path, does not check the capability of the user making the request, and discards the result of its own CSRF check, allowing any authenticated user, such as a subscriber, to delete arbitrary files on the server, which can lead to a site takeover.

Affected products

• Unknown Webtotem Backups: before 1.1.0 (fixed in 1.1.0)
