Overview

The WP Email Debug plugin for WordPress contains a critical privilege escalation vulnerability (CVE-2025-5486) discovered in versions 1.0 to 1.1.0. The vulnerability was disclosed on June 6, 2025, and stems from a missing capability check in the WPMDBUGhandlesettings() function, affecting the WordPress plugin's authentication mechanism (NVD, AttackerKB).

Technical details

The vulnerability is caused by a missing authorization check in the WPMDBUGhandlesettings() function, which allows unauthenticated attackers to modify email settings. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (Critical) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and no required privileges or user interaction (Wordfence).

Impact
