Last updated on: 2025-11-13

Assigner: WSO2 LLC

Description
A reflected cross-site scripting (XSS) vulnerability exists in the authentication endpoints of multiple WSO2 products due to a lack of output encoding. A malicious actor can inject arbitrary JavaScript payloads into the authentication endpoint, which are reflected back in the response, enabling browser-based attacks. Exploitation may result in redirection to malicious websites, UI manipulation, or unauthorized data access from the victim’s browser. However, session-related cookies are protected with the httpOnly flag, which mitigates session hijacking via this vector.

Executive Summary

This vulnerability is a reflected cross-site scripting (XSS) issue in the authentication endpoints of multiple WSO2 products. It occurs because the application does not properly encode output, allowing an attacker to inject arbitrary JavaScript code into the authentication response. This malicious code is then executed in the victim's browser when they interact with the affected endpoint.

Impact Analysis

Exploitation of this vulnerability can lead to redirection of users to malicious websites, manipulation of the user interface, or unauthorized access to data within the victim's browser. However, session hijacking is mitigated because session cookies are protected with the httpOnly flag, preventing attackers from stealing session cookies via this attack vector.
