Admin account needed so PR:H; network-reachable upload with low complexity (AV:N/AC:L); code escapes the app to compromise the root host, so S:C with full C/I/A impact.

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.

AnalysisAI
Remote code execution in Budibase self-hosted server before 3.41.3 lets authenticated administrators run arbitrary JavaScript by uploading a crafted plugin tarball, which the server passes to eval() unsandboxed in the main Node.js process. Because default deployments run that process with root privileges, an attacker who reaches an admin account can read environment variables and stored credentials and fully compromise the host. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Budibase administrator account (CVSS PR:H) and the ability to reach the server's plugin upload functionality over the network (AV:N); the specific trigger is uploading a malicious plugin tarball containing JavaScript, which the server executes via unsandboxed eval() in its main Node.js process. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are largely consistent and point to a high-priority, high-impact bug tempered by a meaningful access barrier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to Budibase 3.41.3 or later, which is the primary and recommended fix (see GHSA-gwr2-pgg3-p7xp). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all systems running Budibase and determine their version, restrict administrative access to Budibase to essential personnel only, and enable monitoring for suspicious administrative activities and plugin uploads. …
