CVE-2022-46813Network attack vector

Settings changes via missing nonce validation

Published May 23, 2023 · Updated Apr 28, 2026

CSRF in SigmaPlugin Advanced Database Cleaner 3.1.1 and earlier allows remote attackers to change plugin settings via forged requests. The aDBc_save_settings_callback settings handler accepts state-changing requests without valid WordPress nonce verification. Exploitation requires an administrator with an active session to open attacker-controlled content, and the reported consequence is limited to unauthorized plugin-setting changes.
