CVE-2026-5002Network attack vector

Unauthenticated routing manipulation via prompt injection

Published Mar 28, 2026 · Updated Mar 28, 2026

Prompt injection in localGPT at commit 4d41c7d1713b16b216d8e062e51a5dd88b20b054 allows remote attackers to manipulate LLM routing decisions. The _route_using_overviews function interpolates the HTTP chat query directly into the router instruction before sending it to Ollama, so injected instructions can override the requested USE_RAG or DIRECT_LLM response. The unauthenticated message endpoint reaches this path when a session has linked document indexes, affecting whether private-document retrieval is used rather than directly executing system commands.
