Security Advisory WSO2-2025-4577/CVE-2025-10503¶

Published: 2026-01-26

Version: 1.0.0

Severity: Medium

CVSS Score: 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

CVE IDs: CVE-2025-10503

AFFECTED PRODUCTS¶

WSO2 Identity Server: 7.1.0

OVERVIEW¶

Reflected Cross-Site Scripting (XSS) has been identified in the authentication endpoint.

DESCRIPTION¶

Due to improper output encoding, a Reflected Cross-Site Scripting (XSS) attack can be carried out by injecting a malicious payload through an unrestricted user input.

IMPACT¶

By leveraging the XSS attack, a malicious actor can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser, or cause harm otherwise. However, since all the session-related sensitive cookies are set with the httpOnly flag and protected, session hijacking or similar attacks would not be possible.
