CVE-2025-5770

Reflected Cross-Site Scripting (XSS) in Authentication Endpoints of Multiple WSO2 Products

Published Nov 5, 2025 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed
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.
