Who should care

WordPress administrators, site owners, and security teams that still run Mail Masta (mail-masta) plugin 1.0 should treat this as a priority finding, especially on sites where plugin admin access is broadly delegated or poorly monitored.

Technical summary

NVD identifies the weakness as CWE-89 (SQL Injection) in Mail Masta 1.0 for WordPress. The affected component is /inc/lists/view-list.php, with the filter_list GET parameter as the injection point. The published CVSS v3.0 vector is AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, indicating network reachability, low attack complexity, required high privileges, and potentially severe impact if exploited through authenticated admin access.

Defensive priority

High

Recommended defensive actions

  • Confirm whether Mail Masta 1.0 is installed anywhere in the WordPress estate and document every affected site.
  • Remove or replace the plugin if it is no longer required; if it must remain, verify whether a fixed release exists before continuing use.
  • Restrict WordPress admin access to the smallest possible group and review privileged accounts tied to the plugin.
  • Review web and application logs for unusual requests to /inc/lists/view-list.php and the filter_list parameter.
  • Validate database and application integrity after exposure, since the vulnerability can affect confidentiality, integrity, and availability.
  • Track the official CVE and NVD records for any later status changes or additional vendor guidance.
