## What is CVE-2026-2144?

CVE-2026-2144 is a high-severity vulnerability in katsushi-kawamori Magic Login Mail or QR Code, published on 14 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-269 (Improper Privilege Management)
