Java vulnerability analysis and mitigation

Overview

An authenticated stored cross-site scripting (XSS) vulnerability exists in multiple WSO2 products, identified as CVE-2025-4760. The vulnerability was discovered and disclosed on September 23, 2025, affecting the Publisher portal of WSO2 products. The vulnerability stems from improper validation of user-supplied input during API document upload functionality (NVD).

Technical details

The vulnerability is classified as a stored XSS issue (CWE-79) with a CVSS v3.1 base score of 4.8 (Medium) and vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N. The vulnerability requires high privileges (publisher access) and user interaction to be exploited. The attack vector is network-accessible, with low attack complexity (NVD).

Impact

If successfully exploited, the vulnerability could lead to redirection to malicious websites, unauthorized UI modifications, or exfiltration of browser-accessible data. However, the impact is partially mitigated as session-related sensitive cookies are protected by the httpOnly flag, preventing session hijacking (NVD).

Mitigation and workarounds

For detailed mitigation instructions, refer to the WSO2 security advisory (WSO2 Advisory).
