What is CVE-2025-0209?

A reflected cross-site scripting (XSS) vulnerability exists in the account registration flow of WSO2 Identity Server due to improper output encoding. This flaw allows a malicious actor to inject a crafted JavaScript payload, which is then reflected in the server's response, enabling execution in the victim's browser. As a result, attackers could redirect users to malicious websites, alter the user interface, or extract data from the browser. The risk of session hijacking is somewhat mitigated, as session-related sensitive cookies are secured with the httpOnly flag.

Affected Version(s)

WSO2 Identity Server 7.0.0 < 7.0.0.87
