Who should care

WordPress administrators, site owners running Mail Masta 1.0, vulnerability management teams, and anyone responsible for plugin inventory and patching on WordPress deployments.

Technical summary

NVD identifies the affected CPE as mail-masta_project mail-masta 1.0 for WordPress and assigns CWE-89 (SQL Injection). The CVSS vector is CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, which indicates network exploitation, low complexity, no user interaction, and a high-privilege prerequisite. The vulnerable code path is /inc/campaign_save.php, where the list_id POST parameter is implicated. Public references linked by NVD/MITRE include a GitHub repository, WPVulnDB entry, and Exploit-DB listing.

Defensive priority

High for any environment that still has Mail Masta 1.0 installed. Because exploitation requires WordPress admin privileges, the exposure is narrower than unauthenticated bugs, but the potential impact remains severe.

Recommended defensive actions

  • Inventory WordPress sites for the Mail Masta / mail-masta plugin and confirm whether version 1.0 is present.
  • Remove or update the plugin if a fixed version is available; if no trusted fix exists, disable and uninstall it.
  • Restrict and monitor WordPress admin access, especially for accounts that can reach plugin functionality.
  • Review server and application logs for unusual requests to /inc/campaign_save.php and unexpected SQL-related errors.
  • Validate database integrity and recent campaign-related changes if the plugin was in use during the exposure window.
  • Use web application firewall or application-layer controls as a compensating measure only if immediate removal is not possible.
