]| Parameter | Position | Path | Description | CWE |
|---|---|---|---|---|
| workflow_run_backend_id | path | CreateArtifact | The backend accepts a caller-supplied workflow_run_backend_id for CreateArtifact without verifying ownership, enabling unauthorized access or manipulation of artifacts. | CWE-321, CWE-862 |
| artifact_name | path | CreateArtifact | The backend accepts a caller-supplied workflow_run_backend_id for CreateArtifact without verifying ownership, enabling unauthorized access or manipulation of artifacts. | CWE-321, CWE-862 |
| task_id | path | CreateArtifact | The backend accepts a caller-supplied workflow_run_backend_id for CreateArtifact without verifying ownership, enabling unauthorized access or manipulation of artifacts. | CWE-321, CWE-862 |
| workflow_run_backend_id | path | GetSignedArtifactURL | Signed URLs are generated with a hardcoded HMAC and insufficient binding, making signatures forgeable and allowing access to artifacts across different runs; the backend also trusts an attacker-supplied workflow_run_backend_id. | CWE-321, CWE-862 |
| artifact_name | path | GetSignedArtifactURL | Signed URLs are generated with a hardcoded HMAC and insufficient binding, making signatures forgeable and allowing access to artifacts across different runs; the backend also trusts an attacker-supplied workflow_run_backend_id. | CWE-321, CWE-862 |
| expiry | path | GetSignedArtifactURL | Signed URLs are generated with a hardcoded HMAC and insufficient binding, making signatures forgeable and allowing access to artifacts across different runs; the backend also trusts an attacker-supplied workflow_run_backend_id. | CWE-321, CWE-862 |
| task_id | path | GetSignedArtifactURL | Signed URLs are generated with a hardcoded HMAC and insufficient binding, making signatures forgeable and allowing access to artifacts across different runs; the backend also trusts an attacker-supplied workflow_run_backend_id. | CWE-321, CWE-862 |
| workflow_run_backend_id | path | ListArtifacts | ListArtifacts accepts a caller-supplied workflow_run_backend_id and does not validate ownership, enabling enumeration of artifacts for other jobs. | CWE-321, CWE-862 |
| workflow_run_backend_id | path | FinalizeArtifact | FinalizeArtifact can be invoked with a caller-supplied workflow_run_backend_id without ownership checks, allowing tampering with artifact finalization for non-owned workflows. | CWE-321, CWE-862 |
| artifact_name | path | FinalizeArtifact | FinalizeArtifact can be invoked with a caller-supplied workflow_run_backend_id without ownership checks, allowing tampering with artifact finalization for non-owned workflows. | CWE-321, CWE-862 |
