CVE-2026-5000Network attack vector

Data access and modification via unauthenticated handlers

Published Mar 28, 2026 · Updated Mar 28, 2026

Missing authentication in PromtEngineer localGPT 4d41c7d1713b16b216d8e062e51a5dd88b20b054 allows remote attackers to access API data and operations. ChatHandler in backend/server.py routes GET, POST, and DELETE requests directly to session, index, upload, and chat handlers without checking credentials. Network access to the backend service is sufficient to read or change stored application data and invoke operations without user interaction.
