This issue affects the function createTempFolder of the file /api/plugin/upload of the component Plugin File Upload Endpoint. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22.

Impacted is integrity, and availability. The summary by CVE is: 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. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-35214 since 04/01/2026. The exploitation is known to be easy.
