CVE-2025-6623
Stored Cross-Site Scripting via XML Input in Multiple WSO2 Products Allows UI Manipulation and Redirection
CVSS Score
4.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
