CVE-2020-36848Public exploitNetwork attack vector

Unauthenticated backup download via exposed restore metadata

Published Jul 12, 2025 · Updated Apr 8, 2026

Information exposure in BoldGrid Total Upkeep 1.14.9 and earlier allows remote attackers to download WordPress backup archives. The plugin leaves cron/restore-info.json and cli/env-info.php web-accessible; restore metadata discloses the randomized archive path, which the server then serves without authentication. Network access to the WordPress site is sufficient, and exposed archives can contain site files, database contents, and credential hashes.
