Vulnerability Title
AgentFlow Local Web API Content-Type Validation Bypass
Source: NVD (National Vulnerability Database)
Vulnerability 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.
