CVE-2022-2133Public exploitNetwork attack vector

Account takeover via unvalidated OAuth requests

Published Jul 17, 2022 · Updated Aug 3, 2024

Improper authentication in miniOrange OAuth Single Sign On before 6.22.6 allows remote attackers to access accounts using only an email address. The public mooauth request handler accepts a supplied email address and creates a login without validating a legitimate OAuth access token. No authentication or user interaction is required; knowledge of a registered address grants the privileges of that WordPress account.
