WordPress vulnerability analysis and mitigation

The DJ EmailPublish WordPress plugin version 1.7.2 and earlier contains a Reflected Cross-Site Scripting vulnerability. The vulnerability exists due to improper handling of the $SERVER["PHPSELF"] value in the ~/dj-email-publish.php file, which was discovered and disclosed in September 2021 (NVD).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). It has been assigned a CVSS v3.1 base score of 6.1 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating that it is network-accessible, requires low attack complexity, needs no privileges, but does require user interaction (NVD).

If exploited, this vulnerability allows attackers to inject arbitrary web scripts that execute in the context of the affected website. This could lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the affected user's session (NVD).

Users should update to a version newer than 1.7.2 if available, or consider implementing additional security controls such as Web Application Firewalls to filter potentially malicious requests (NVD).
