No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A security flaw has been discovered in Hulupeep mcp-ui-probe up to 0.2.0. Affected is the function get_journey/delete_journey/analyze_journey/usage_stats of the file src/journey/JourneyStorage.ts of the component Journey/Usage. The manipulation of the argument journeyId/filename results in path traversal. The attack requires a local approach. The project was informed of the problem early through an issue report but has not responded yet.
