Summary

AgentFlow's local web API accepts non-JSON content types on POST /api/runs and POST /api/runs/validate endpoints without enforcing application/json validation, allowing attackers to bypass trust-boundary enforcement on sensitive operations. Attackers can exploit this content-type validation weakness through browser-driven or local cross-origin requests to abuse the localhost API and enable attack chains against the local control plane.

Risk Assessment

An attacker could bypass trust-boundary enforcement and abuse the local API for sensitive operations, potentially leading to further attacks on the local control plane. The risk applies to systems running AgentFlow with the local web API exposed.

Recommendation

Update AgentFlow to a version that enforces application/json validation on POST endpoints. Restrict access to the local web API to trusted clients only.
