{"id":"CVE-2026-73308","aliases":["GHSA-gh4h-34gr-87r7"],"url":"https://o3.security/vulnerability/CVE-2026-73308","summary":"Budibase: OAuth2 Token Disclosure via Automation Test Results Broadcast to Other Builders","details":"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.","published":"2026-08-12T19:01:15.182Z","modified":"2026-08-13T04:02:50.341127814Z","cvss":{"score":5.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@budibase/server","fixedVersion":null}],"fix":{"url":"https://github.com/Budibase/budibase/commit/bca426de7dc36d680285295655dc640dea2aab21","label":"Budibase/budibase@bca426d"},"references":[{"type":"FIX","url":"https://github.com/Budibase/budibase/commit/bca426de7dc36d680285295655dc640dea2aab21"},{"type":"FIX","url":"https://github.com/Budibase/budibase/pull/19107"},{"type":"WEB","url":"https://github.com/Budibase/budibase/releases/tag/3.39.25"},{"type":"ADVISORY","url":"https://github.com/Budibase/budibase/security/advisories/GHSA-gh4h-34gr-87r7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73308.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73308"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T04:02:50.341127814Z"}}
