Affected versions of this package are vulnerable to Improper Input Validation via the HTML entity decoding logic in the client-side PDF export pipeline. An attacker can exploit this vulnerability by supplying specially crafted input containing nested or malformed HTML entities that are double-unescaped in the downloadPdf function of the src/local_deep_research/web/static/js/services/pdf.js component, allowing encoded payloads to be transformed into executable markup after multiple decoding passes.
