CVE-2026-56231

7.2 HIGH 0.3% exploit odds Fix listed Denial of service Server

What it is

Capgo before 12.128.2 contains a broken object level authorization (BOLA) vulnerability in the POST /build/start/:jobId and POST /build/cancel/:jobId endpoints. The handlers authorize the request based only on the attacker-controlled app_id supplied in the request body and never verify that the jobId in the URL belongs to that app_id (or the same tenant/org) before issuing privileged builder commands with the server-held builder API key. An authenticated user with the app.build_native permission for any app they control can start or cancel arbitrary builder jobs belonging to other tenants by supplying a victim jobId, resulting in cross-tenant build sabotage (denial of service), unauthorized compute actions, and potential billing impact.
