## Description

Langfuse is an open source large language model engineering platform. In versions from 2.95.0 to before 2.95.12 and from 3.17.0 to before 3.131.0, in SSO provider configurations without an explicit AUTH\_\<PROVIDER\>\_CHECK setting, a potential account takeover may happen if an authenticated user is made to call a specifically crafted URL via a CSRF or phishing attack. This issue has been patched in versions 2.95.12 and 3.131.0. A workaround for this issue involves setting AUTH\_\<PROVIDER\>\_CHECK.
