CVE-2026-7439

Local control-plane abuse via missing Content-Type enforcement

Published Apr 29, 2026 · Updated Apr 29, 2026

Improper request validation in Bera Buddies AgentFlow before 1667fa3 allows local users to abuse its web API via non-JSON requests. The run-creation and validation routes parsed request bodies without first rejecting content types other than application/json. Browser interaction or local access is required; successful requests broaden abuse of the localhost control plane but do not alone establish code execution.
