Lifecycle Timeline
3DescriptionCVE.org
Budibase before 3.40.0 fails to redact datasource credentials stored in STRING typed fields, allowing authenticated users to read MongoDB connection strings and Firebase private keys in plaintext. Attackers with table read permissions can retrieve datasource configurations through the read API to obtain live backend database credentials and service account keys.
AnalysisAI
Credential plaintext exposure in Budibase before 3.40.0 allows any authenticated user with table read permissions to retrieve live MongoDB connection strings and Firebase private keys via the standard read API. The root failure is that STRING-typed datasource fields bypass the platform's credential redaction logic entirely, leaving secrets accessible through normal API calls. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Budibase user account with table read permissions - unauthenticated access is not possible per the CVSS PR:L metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.3 is well-calibrated to the actual risk profile. … 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 | Upgrade Budibase to version 3.40.0 or later, which introduces proper credential redaction for STRING-typed datasource fields. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit all Budibase instances to identify those running versions prior to 3.40.0 and document which users have table read permissions; simultaneously, contact Budibase for guidance on interim mitigation options. …
