Trigger.dev: Account Takeover via Cross-Provider OAuth Email Matching in Google Login
Description

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.
