Attack-Flow Graph

Executive Summary

This vulnerability involves insufficient validation of OIDC SSO provider configuration. A user with high privileges could exploit this to redirect requests to arbitrary destinations, potentially leading to unauthorized access or data leakage.

Detection Guidance

This vulnerability involves insufficient validation of OIDC SSO provider configuration. Detection requires reviewing OIDC SSO provider settings for misconfigurations or unauthorized redirections. Check logs for unusual request patterns or unexpected destination URLs in authentication flows.

Impact Analysis

The impact includes unauthorized request redirection, which may allow attackers to access sensitive data or perform actions on behalf of legitimate users. Systems relying on OIDC SSO for authentication could be compromised.
