AuditPilot before commit 4669c93 RAG Project-Scope Authorization Bypass via project_id

AuditPilot before commit 4669c93 contains an authorization bypass vulnerability in _metadata_allowed in rag/agentic_rag.py that allows authenticated users to read other projects' knowledge by supplying project_id. Attackers with read:knowledge scoped to one project can set context.project_id via GET /api/knowledge/query or POST /api/research/answer to retrieve same-tenant project knowledge chunks.
