Stored Cross-Site Scripting via XML Input in Multiple WSO2 Products Allows UI Manipulation and Redirection

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
