Description
An authenticated stored Cross-Site Scripting (XSS) vulnerability exists in WSO2 API Manager components (carbon-apimgt) due to insufficient validation of user-supplied input during API document upload in the Publisher portal.
A user with publisher privileges can upload a crafted API document whose contents are later rendered in the UI for other users, leading to attacker-controlled script execution. Likely outcomes include redirection to malicious sites, unauthorized UI modifications, or exfiltration of data accessible to the browser; session hijacking is mitigated by the use of HttpOnly session cookies.
To remediate, update to version 9.31.117 or above.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.wso2.carbon.apimgt:org.wso2.carbon.apimgt.api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wso2.carbon.apimgt:org.wso2.carbon.apimgt.api to 9.31.117 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-4760 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
