CVE-2026-73655: CWE-287: Improper Authentication in triggerdotdev trigger.dev
Trigger.dev versions prior to 4.5.2 contain an improper authentication vulnerability in the Google authentication flow. The vulnerability allows an attacker to link an unverified Google email profile to an existing account with the same email, potentially taking over that account. This issue is resolved in version 4.5.2.
AI Analysis
Technical Summary
Trigger.dev's addGoogleStrategy() function in versions before 4.5.2 does not verify the 'email_verified' assertion from Google's profile data before passing the email to findOrCreateGoogleUser(). When a Google profile with an unverified email matches an existing email user but not an existing Google user, the system writes the new Google authIdentifier into the existing account and returns that user object. This improper authentication flaw (CWE-287) enables an attacker controlling a Google profile with an unverified matching email to take over the account associated with that email. The vulnerability is fixed in version 4.5.2.
Potential Impact
An attacker can take over user accounts by linking an unverified Google profile email to an existing account with the same email address. This leads to full compromise of the affected user account's confidentiality and integrity. Availability is not impacted.
Mitigation Recommendations
Upgrade to trigger.dev version 4.5.2 or later, where this vulnerability is fixed by requiring Google's email_verified assertion before associating Google profiles with existing accounts. No other mitigation is indicated.
