jsondiffpatch before 0.7.7 contains a cross-site scripting vulnerability that allows attackers to inject markup by supplying an unescaped array-move destination index in a delta. Attackers who control a delta passed to formatters.html.format() or formatters.annotated.format() can embed script that executes in the application's origin when output is rendered.
