CVE-2026-56619Network attack vector

Authenticated script execution via insufficient output encoding

Published Aug 10, 2026 · Updated Aug 10, 2026

Reflected XSS in HCL BigFix Mobile 3.6 and earlier allows remote authenticated users to execute scripts through crafted input. Response generation insufficiently validates or encodes user-controlled input before reflecting it into a web page; HCL has not named the endpoint or parameter. Exploitation requires low-privileged access and victim interaction, exposing browser-session data to script reads or modification.
