| Descrição | OIDC account takeover via unverified email linking in TREK <= 3.0.22. The findOrCreateUser function in oidcService.ts automatically links incoming OIDC identities to existing password-based accounts by matching email addresses (case-insensitive) without verifying the email_verified claim. An attacker using an IdP that does not enforce email verification can set their profile email to match a victim's TREK account email and gain durable login access through SSO, achieving complete account takeover. CVSS 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). CWE-287. Fixed in 3.1.0. |
