CVE-2026-35214

Budibase is an open-source low-code platform. Prior to version 3.33.4, the plugin file upload endpoint (POST /api/plugin/upload) passes the user-supplied filename directly to createTempFolder() without sanitizing path traversal sequences. An attacker with Global Builder privileges can craft a multipart upload with a filename containing ../ to delete arbitrary directories via rmSync and write arbitrary files via tarball extraction to any filesystem path the Node.js process can access. This issue has been patched in version 3.33.4.
