CVE-2026-2144 — The Magic Login Mail or QR Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.05

High CVSS 8.1

The Magic Login Mail or QR Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.05. This is due to the plugin storing the magic login QR code image with a predictable, static filename (QR_Code.png) in the publicly accessible WordPress uploads directory during the email sending process. The file is only deleted after wp_mail() completes, creating an exploitable race condition window. This makes it possible for unauthenticated attackers to trigger a login link request for any user, including administrators, and then exploit the race condition between QR code file creation and deletion to obtain the login URL encoded in the QR code, thereby gaining unauthorized access to the targeted user's account.

Matched remediation archetype

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
