CVE-2026-112775
HIGH 8.7Craft CMS from 5.0.0 before 5.11.0 contains an authentication bypass vulnerability that allows attackers to reuse verification codes because users/verify-email does not invalidate them for active users. Attackers who obtain a victim's emailed code can submit it to users/set-password after the victim verifies an email change, resetting the password and taking over the account.
Severe if exploited (CVSS 8.7), but no known exploitation and low modeled probability. Patch on a normal cadence.
