Attack-Flow Graph

Executive Summary

OpenPanel logs Model Context Protocol authentication tokens from URL query parameters in plaintext without redaction. Attackers with access to logs can capture these base64-encoded credentials to replay MCP requests and access project analytics.

Detection Guidance

Check application logs for base64-encoded strings in URL query parameters. Search for patterns like 'token=' or 'mcp_token=' in stdout or log files. Use commands like 'grep -r "token=" /var/log/' or 'journalctl -u openpanel --no-pager | grep -i token' to inspect logs.

Impact Analysis

If you use OpenPanel, attackers with log access could steal credentials and gain unauthorized access to your project analytics. This could lead to data breaches or misuse of sensitive information.

Compliance Impact

This vulnerability could violate GDPR or HIPAA by exposing sensitive authentication tokens in logs, potentially leading to unauthorized data access. Compliance may be impacted due to insufficient protection of credentials.

Mitigation Strategies

Disable logging of URL query parameters in the application configuration. Update OpenPanel to a version that redacts sensitive tokens from logs. Rotate any exposed MCP authentication tokens immediately.
