CVE-2025-12544

Stored Cross-Site Scripting in Multiple WSO2 Products

publishedCWE-79

The Publisher portal fails to enforce proper validation on uploaded SVG files, allowing users with the Publisher role to inject malicious scripts. This weakness can be exploited by uploading a crafted SVG file, which is then stored and rendered by the application. The security consequences include the ability for a malicious actor to redirect the victim's browser to an arbitrary website, modify the web page's UI, or retrieve information from the browser. However, the impact is mitigated as session-related sensitive cookies are protected with the httpOnly flag, preventing session hijacking.
