Authenticated file read via unconfined browser-items path
Published Aug 26, 2026 · Updated Aug 26, 2026
Path traversal in Mage AI Mage 0.9.79 and earlier allows remote authenticated users to read server files via the browser-items API. BrowserItemResource decodes the route path and passes it to Item.load, whose file helpers read an absolute path without checking project-directory containment. Viewer access is sufficient in the default permission configuration, exposing any file readable by the server process; Editor access also permits writes.
