CVE-2020-36948Public exploitNetwork attack vectorHinoki check available

Account takeover via null LoginAs token

Published Jan 27, 2026 · Updated Jan 27, 2026

Incorrect authorization in Vesta Control Panel 0.9.8-26 allows remote authenticated users to access other accounts through LoginAs requests. The /login/ handler accepts a loginas account value with token=null and switches the session without validating an administrator token. A basic user session is required; successful exploitation exposes another account's data and grants that account's panel privileges.
