Summary
Budibase versions before 3.41.3 contain a remote code execution vulnerability in plugin handling that allows authenticated admin users to execute arbitrary code by uploading a malicious plugin tarball. The server calls eval() on plugin JavaScript files without sandboxing in the main Node.js process, enabling attackers to exfiltrate environment variables and credentials with root privileges in default deployments.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of Budibase/budibase published their own advisory on GitHub. Reviewed sources take precedence over it.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
