CVE-2026-66435Network attack vectorHinoki check available

Sensitive-data disclosure via insufficient backup-folder privacy

Published Oct 10, 2026 · Updated Oct 10, 2026

Data exposure in Devin Walker WP Rollback 3.1.2 and earlier allows remote attackers to read sensitive data via network requests. The upstream security changelog identifies insufficient backup-folder privacy, but the exact retrieval endpoint and request handling are not publicly described in the inspected material. Authentication and user interaction are unnecessary; disclosure depends on accessible sensitive content, with no documented modification or service interruption.
