Lifecycle Timeline
3DescriptionCVE.org
Budibase is an open-source low-code platform. Prior to 3.39.25, the GET /api/global/groups endpoint in packages/worker/src/api/routes/global/groups.ts omitted auth.builderOrAdmin, allowing an authenticated BASIC role user to enumerate tenant groups, role mappings and user memberships, builder permissions, and default-group flags. The disclosure exposes the tenant access-control structure to users who are not builders or administrators. This issue is fixed in version 3.39.25.
AnalysisAI
Missing RBAC middleware on Budibase's GET /api/global/groups API endpoint allows any authenticated BASIC-role user to enumerate all tenant groups, role-to-application mappings, member user lists, builder permission flags, and default-group designations that should be restricted to builders and administrators. All Budibase versions prior to 3.39.25 are affected across both self-hosted and cloud deployments. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session as any Budibase user holding at minimum the BASIC role - unauthenticated access is not possible, as session authentication is enforced before the missing authorization check would apply. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) is well-calibrated for this vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated BASIC-role user - such as a recently onboarded employee or a low-trust tenant user - sends a standard HTTP GET request to http(s)://[budibase-host]/api/global/groups using their existing session cookie. The endpoint responds with HTTP 200 and a JSON payload listing all tenant groups with their names, role-to-application mappings, member user lists, builder permission flags, and isDefault indicators. … |
| Remediation | Upgrade Budibase to version 3.39.25 or later, which adds the missing auth.builderOrAdmin middleware to the GET /api/global/groups route. … Detailed patch versions, workarounds, and compensating controls in full report. |
