{"id":"CVE-2026-73655","aliases":["GHSA-rp8c-h4xr-w9qv"],"url":"https://o3.security/vulnerability/CVE-2026-73655","summary":"Trigger.dev: Account Takeover via Cross-Provider OAuth Email Matching in Google Login","details":"Trigger.dev is a platform for building and deploying fully managed AI agents and workflows. Prior to 4.5.2, addGoogleStrategy() in apps/webapp/app/services/googleAuth.server.ts passes a Google profile email to findOrCreateGoogleUser() in apps/webapp/app/models/user.server.ts without requiring Google's email_verified assertion. When existingEmailUser && !existingUser is true, the flow writes the new Google authIdentifier into the existing email-matched account and returns that user object, allowing an attacker-controlled Google profile with an unverified matching email to take over the account. This issue is fixed in version 4.5.2.","published":"2026-08-13T19:53:50.490Z","modified":"2026-08-14T04:04:48.030227722Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/triggerdotdev/trigger.dev/commit/34b1a181c2a1d33a53ebab88f84b05f81fea4254","label":"triggerdotdev/trigger.dev@34b1a18"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73655.json"},{"type":"FIX","url":"https://github.com/triggerdotdev/trigger.dev/commit/34b1a181c2a1d33a53ebab88f84b05f81fea4254"},{"type":"FIX","url":"https://github.com/triggerdotdev/trigger.dev/pull/4199"},{"type":"WEB","url":"https://github.com/triggerdotdev/trigger.dev/releases/tag/v4.5.2"},{"type":"ADVISORY","url":"https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-rp8c-h4xr-w9qv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73655"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:04:48.030227722Z"}}
