CVE-2025-10503
Reflected Cross-Site Scripting via Authentication Endpoint in WSO2 Identity Server
CVSS Score
6.1
EPSS Score
0.0%
EPSS Percentile
0th
The authentication endpoint accepts user-supplied input without enforcing expected validation constraints, leading to a lack of proper output encoding. This allows for the injection of malicious JavaScript payloads, enabling reflected cross-site scripting. An attacker can leverage this vulnerability to redirect the user's browser to a malicious website, modify the user interface of the web page, retrieve information from the browser, or cause other harmful actions. However, due to the protection of session-related cookies with the httpOnly flag, session hijacking is not possible.
