CVE-2025-5770: WSO2 API Control Plane

Medium severity, CVSS 6.1. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• WSO2 API Control Plane: version 4.5.0 only
• WSO2 API Manager: version 4.2.0 only; version 4.3.0 only; version 4.4.0 only; version 4.5.0 only
• WSO2 Identity Server: version 6.0.0 only; version 6.1.0 only; version 7.0.0 only; version 7.1.0 only
