CVE-2025-2009:
WordPress vulnerability analysis and mitigation
Overview
The Newsletters plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability (CVE-2025-2009) in versions up to and including 4.9.9.7. The vulnerability exists in the logging functionality due to insufficient input sanitization and output escaping. This security issue was discovered and disclosed on March 26, 2025 (NVD).
Technical details
The vulnerability is classified as a Stored Cross-Site Scripting (CWE-79) issue with a CVSS v3.1 Base Score of 7.2 (HIGH) and vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N. The issue stems from improper neutralization of input during web page generation in the logging functionality of the plugin. The vulnerability was fixed in version 4.9.9.8 by implementing proper output escaping using esctextarea() function for log output ([WordPress Changeset](https://plugins.trac.wordpress.org/changeset/3257980/newsletters-lite/trunk/views/admin/settings/viewlogs.php)).
Impact
This vulnerability allows unauthenticated attackers to inject arbitrary web scripts that will execute whenever a user accesses an injected page. The successful exploitation could lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the affected user's browser (NVD).
Mitigation and workarounds
Users should upgrade to version 4.9.9.8 or later of the Newsletters plugin, which includes the security fix. The fix implements proper output escaping using the esctextarea() function to prevent XSS attacks ([WordPress Changeset](https://plugins.trac.wordpress.org/changeset/3257980/newsletters-lite/trunk/views/admin/settings/viewlogs.php)).
