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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","score":5.7},"cwes":["CWE-200"],"references":["https://github.com/Budibase/budibase/commit/bca426de7dc36d680285295655dc640dea2aab21","https://github.com/Budibase/budibase/pull/19107","https://github.com/Budibase/budibase/releases/tag/3.39.25","https://github.com/Budibase/budibase/security/advisories/GHSA-gh4h-34gr-87r7","https://github.com/Budibase/budibase/security/advisories/GHSA-gh4h-34gr-87r7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-73308","score":0.00407,"percentile":0.35033,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gh4h-34gr-87r7","url":"https://osv.dev/vulnerability/GHSA-gh4h-34gr-87r7","summary":" Budibase: OAuth2 Token Disclosure via Automation Test Results Broadcast to Other Builders","modified":"2026-08-12T19:26:07.589128Z","packages":[{"ecosystem":"npm","name":"@budibase/server","purl":"pkg:npm/%40budibase/server","ranges":["<=3.38.1"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
