GHSA-33vc-wfww-vjfv jsondiffpatch is vulnerable to Cross-site Scripting (XSS) via HtmlFormatter::nodeBegin

• npm jsondiffpatch: < 0.7.2 → fixed in 0.7.2

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.
