Summary
IBM Cloud Pak System 2.3.6.0, and 2.3.6.1 is vulnerable to cross site scripting. The web app user‑supplied input is not properly sanitized or HTML‑encoded before being stored and rendered. An authenticated attacker could exploit this vulnerability by entering specially crafted payloads containing malicious JavaScript which are saved within the app and later executed automatically when user views affected pages, resulting in Stored Cross‑Site Scripting (Stored XSS).
