Description

Craft 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.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-112775 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
