WordPress vulnerability analysis and mitigation

Overview

The Wise Chat plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability (CVE-2025-3774) that affects all versions up to and including 3.3.4. The vulnerability was discovered and disclosed in June 2025 (NVD, Wiz).

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 vulnerability stems from insufficient input sanitization and output escaping of the X-Forwarded-For header (NVD, Wiz).

Impact

This vulnerability allows unauthenticated attackers to inject arbitrary web scripts into pages that will execute whenever a user accesses an injected page. The successful exploitation could lead to theft of sensitive information, manipulation of web content, and potential compromise of user sessions (Wiz).

Mitigation and workarounds

Users should update their Wise Chat plugin to a version newer than 3.3.4 once available. Until then, website administrators should consider implementing additional security controls such as Web Application Firewalls (WAF) to filter malicious requests (Wiz).
