MediumCVSS 5.7Exploitation Probability (EPSS)
Low risk22th percentile - higher than 22% of all known CVEs
Summary
Budibase is an open-source low-code platform. Prior to 3.39.25, packages/server/src/api/controllers/automation.ts returned automation test results containing trigger.outputs.user.oauth2, broadcast BuilderSocketEvent.AutomationTestProgress to the app room, and stored progress in packages/server/src/automations/testProgress.ts without user scoping. A co-builder could receive or poll another SSO-authenticated builder test and obtain OAuth2 access and refresh tokens. The fix adds sanitizeAutomationTestResult and isolates progress by user. This issue is fixed in version 3.39.25.
Risk Assessment
The risk includes unauthorized access to other users' OAuth2 tokens, which can lead to account takeover and data confidentiality breach.
Recommendation
It is recommended to update Budibase to version 3.39.25 or later, which contains the fix.
