Security readout for executives and security teams
Plain-English summary
A WordPress plugin used for magic-login emails or QR codes can briefly place an administrator login QR code in a public uploads folder using a predictable filename. If an attacker times access during that window, they may obtain a login URL and take over the targeted account.
Executive priority
Treat as high priority for WordPress sites using this plugin. Successful exploitation could allow administrator account takeover. Prioritize inventory, temporary disablement, and vendor update verification over broad emergency response unless evidence of exploitation appears.
Technical view
CVE-2026-2144 affects Magic Login Mail or QR Code versions up to and including 2.05. The plugin stores QR_Code.png in the public uploads directory during wp_mail(), deleting it only afterward. This creates a race condition enabling unauthenticated privilege escalation. CVSS is 8.1, high, with high attack complexity.
Likely exposure
Exposure is limited to WordPress sites running the Magic Login Mail or QR Code plugin at version 2.05 or earlier, especially where magic login is enabled for privileged users.
Exploitation context
Sources describe a race condition, not confirmed active exploitation. The CVE is not listed as KEV in the provided bundle. Exploitation requires timing access to a temporary QR image but does not require authentication or user interaction.
Researcher notes
The vulnerability hinges on predictable temporary QR file storage in a public uploads path and deletion after wp_mail() completes. Public sources identify the issue and code references, but the provided bundle does not clearly name a fixed release. Avoid claiming exploitation without additional evidence.
Mitigation direction
- Inventory WordPress sites for the Magic Login Mail or QR Code plugin.
- If version is 2.05 or earlier, check vendor guidance and update availability.
- Disable or remove the plugin until a fixed version is confirmed.
- Avoid using magic login for administrator accounts until remediated.
- Monitor WordPress and web server logs for unusual magic-login requests.
Validation and detection
- Confirm plugin name and version from WordPress administration or asset inventory.
- Verify whether any deployed version is 2.05 or earlier.
- Check vendor plugin repository for a patched release or relevant changeset.
- Review uploads directory exposure and web logs for QR_Code.png access attempts.
- Confirm remediation by documenting updated, removed, or disabled plugin status.
