Report #84376

[architecture] Unauthorized data flows violating privacy boundaries between agents with different clearance levels

Enforce Attribute-Based Access Control \(ABAC\) with propagating security labels \(sensitivity taxonomy like PII/PCI/PHI\) and policy enforcement points at agent boundaries; implement automatic redaction/downgrading based on receiver's clearance before inter-agent transmission.

Journey Context:
Multi-agent systems often mix agents with different data access \(e.g., public-facing agent → internal analytics agent\). Simple allow/deny lists fail because data sensitivity changes with context \(aggregated vs individual\). ABAC allows policies like 'Agent B can receive PII only if purpose=medical\_diagnosis and user\_consent=true'. Tradeoff: label propagation adds overhead to every message; requires centralized policy store.
