What is CVE-2025-6623?
CVE-2025-6623 is a medium-severity cross-site scripting vulnerability in WSO2 API Control Plane, published on 19 Oct 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
The carbon console accepts user-supplied XML input without sufficiently encoding potentially executable content, allowing for the injection of malicious scripts.
Successful exploitation allows a remote attacker to execute arbitrary JavaScript in the context of a victim's browser, leading to actions such as redirecting the user to a malicious website or modifying the web page's user interface. Session hijacking is not possible as sensitive session cookies are protected by the httpOnly flag.
