EPSS

• CVE-2016-4316: 4.00% estimated exploitation activity in the next 30 days; percentile 90.54 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Multiple cross-site scripting (XSS) vulnerabilities in WSO2 Carbon 4.4.5 allow remote attackers to inject arbitrary web script or HTML via the (1) setName parameter to identity-mgt/challenges-mgt.jsp; the (2) webappType or (3) httpPort parameter to webapp-list/webappinfo.jsp; the (4) dsName or (5) description parameter to ndatasource/newdatasource.jsp; the (6) phase parameter to viewflows/handlers.jsp; or the (7) url parameter to ndatasource/validateconnection-ajaxprocessor.jsp.

# Patch Next advisory brief: CVE-2016-4316

Advisory: WSO2 Carbon vulnerable to Cross-site Scripting
IDs: CVE-2016-4316, GHSA-2vcm-2mcr-wmx7
Record: https://patchnext.com/advisories/cve-2016-4316 (revision 1, source checked 26 Oct 2026, 16:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.wso2.carbon.commons:org.wso2.carbon.ndatasource.ui: affected <= 4.4.5
- Maven org.wso2.carbon.commons:org.wso2.carbon.messageflows.ui: affected <= 4.4.5
- Maven org.wso2.carbon.identity.framework:org.wso2.carbon.identity.mgt.ui: affected <= 4.4.5

## Suggested inspection (read-only)
- Maven org.wso2.carbon.commons:org.wso2.carbon.ndatasource.ui: check the installed version with your package manager.
- Maven org.wso2.carbon.commons:org.wso2.carbon.messageflows.ui: check the installed version with your package manager.
- Maven org.wso2.carbon.identity.framework:org.wso2.carbon.identity.mgt.ui: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.wso2.carbon.commons:org.wso2.carbon.ndatasource.ui, org.wso2.carbon.commons:org.wso2.carbon.messageflows.ui, org.wso2.carbon.identity.framework:org.wso2.carbon.identity.mgt.ui.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
