Detailsinfo

A vulnerability was found in Trigger.dev up to 4.5.1. It has been declared as critical. This vulnerability affects the function addGoogleStrategy of the file apps/webapp/app/services/googleAuth.server.ts of the component Google Authentication. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-73655 since 08/13/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit.
