CVE-2026-112775 craftcms CVE debrief
CVE-2026-112775 is a high-severity authentication bypass vulnerability in Craft CMS versions 5.0.0 before 5.11.0. Attackers can reuse verification codes to gain unauthorized access to user accounts. This vulnerability allows attackers to bypass authentication by reusing verification codes because the users/verify-email endpoint does not invalidate verification codes for active users. Defenders should prioritize verifying and upgrading to version 5.11.0 or later, and implement additional monitoring for suspicious account activity.
