CVE-2023-5982Network attack vector

Backup redirection via forged Google Drive authorization

Published Nov 7, 2023 · Updated Apr 8, 2026

Cross-site request forgery in UpdraftPlus 1.23.10 and earlier allows remote attackers to redirect site backups to Google Drive. The updraftmethod-googledrive-auth action updates the remote-storage instance_id without nonce validation or sufficient identifier validation. Exploitation requires a signed-in site administrator to submit a forged request, after which backups containing sensitive site data can reach attacker-controlled storage.
