If you cannot patch yet, users should restrict access to the local API endpoints and consider implementing network-level controls to prevent unauthorized cross-origin requests to localhost.
Description
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.
