Summary
jsondiffpatch is vulnerable to Cross-site Scripting (XSS) via HtmlFormatter::nodeBegin
Details

Vulnerability in jsondiffpatch

Versions of jsondiffpatch prior to 0.7.2 are vulnerable to Cross-site Scripting (XSS) in the HtmlFormatter (HtmlFormatter::nodeBegin). When diffs are rendered to HTML using the built-in formatter, untrusted payloads can inject scripts and execute in the context of a consuming web page.

Affected versions: >= 0, < 0.7.2 Patched version: 0.7.2

Remediation Upgrade to jsondiffpatch 0.7.2 or later. The fix hardens the HTML formatter to avoid script injection.

Workarounds Avoid using the HTML formatter on untrusted diffs, or sanitize/escape the rendered output.
