ParameterPositionPathDescriptionCWE
jobIdpath/build/logs/:jobIdPrivilege inversion: read-only API keys can cause cancellation of native builds by opening the SSE log stream and disconnecting, triggering cancelBuildOnDisconnect() with the privileged BUILDER_API_KEY and bypassing the app.build_native permission check.CWE-862
jobIdpath/build/cancel/:jobIdCancellation endpoint meant to stop native builds; exploited indirectly when read-only API keys abuse /build/logs/:jobId to cancel via cancelBuildOnDisconnect, bypassing permission checks.CWE-862
