Executive Summary

This vulnerability affects Langfuse versions 2.95.0 to before 2.95.12 and 3.17.0 to before 3.131.0 when using SSO provider configurations without an explicit AUTH_<PROVIDER>_CHECK setting. An authenticated user can be tricked via a CSRF or phishing attack into calling a specially crafted URL, potentially leading to an account takeover. The issue has been fixed in versions 2.95.12 and 3.131.0, and a workaround is to set AUTH_<PROVIDER>_CHECK.

Impact Analysis

The vulnerability can lead to a potential account takeover if an authenticated user is tricked into calling a malicious URL via CSRF or phishing. This means an attacker could gain unauthorized access to user accounts, compromising account security and potentially sensitive data.

Mitigation Strategies

To mitigate this vulnerability, immediately update Langfuse to version 2.95.12 or later, or 3.131.0 or later. As a workaround, configure the AUTH_<PROVIDER>_CHECK setting explicitly in your SSO provider configurations to prevent potential account takeover via CSRF or phishing attacks.
