CVE-2026-55413Public exploitNetwork attack vector

Server RCE via globally shared plugin overwrite

Published Jun 25, 2026 · Updated Jun 25, 2026

Code injection in ToolJet before 3.20.178-lts allows remote authenticated users with builder access to execute server-side JavaScript. The PATCH /api/plugins/:id path lets any builder replace a global plugin from an arbitrary GitHub repository, then vm.runInNewContext exposes require and process to the fetched code. A builder account and one installed marketplace plugin are required; a later plugin query runs the payload with the server process's access across the instance.
