CVE-2025-5770 – Reflected Cross-Site Scripting (XSS) in Authentication Endpoints of Multiple WSO2 Products

CVE ID : CVE-2025-5770

Published : Nov. 5, 2025, 7:02 p.m. | 26 minutes ago

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.

Severity: 6.1 | MEDIUM
