CVE-2026-60009

NVD: In Eclipse Theia versions up to and including 1.73.1, the @theia/filesystem backend binds POST /file-upload in every filesystem-enabled deployment. NVD: The handler takes an attacker-supplied absolute path from the multipart uri field and calls fs.move(tmp, target, { overwrite: true }) with no workspace confinement and no authentication. NVD: In browser (non-Electron) deployments the connection token is enforced only on WebSocket upgrades; the HTTP middleware in @theia/core re-issues the cookie and calls next() without rejecting tokenless HTTP requests.
