CVE-2026-35214: Budibase is an open-source low-code platform
CVE-2026-35214 is a high-severity flaw (CVSS 8.7) affecting budibase. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 filesyste
