# Disable legacy JQuery UI usage

Avoid the introduction of unpatched vulnerabilities in the library by disabling legacy JQuery UI usage.
Prevent the use of older prepatched JQuery UI versions, which introduce unpatched vulnerabilities in the library. Using old versions can potentially lead to security risks arising from attacks on vulnerabilities discovered in
outdated JQuery UI library versions.

Confirm that the glide.jquery_ui.legacy system property is set to false to prevent older prepatched JQuery UI versions from being used. This system property is a failsafe in case
organizations depend on the non-patched versions to run their custom implementations.
