Root Cause Analysis
The commit diff shows added permission checks in these methods. The vulnerability stems from missing Run.ARTIFACTS
checks in: 1) getArtifacts()
which returns artifact metadata, 2) doDownload()
which handles file downloads, and 3) getLatestDeployedArtifacts()
which provides project-level artifact info. The patch added explicit permission verification in all these endpoints, confirming they were previously vulnerable access points.
