Workarounds
CNA: The following practices would help for avoiding exposure and mitigate this flaw: - Upgrade Pen Drive to version 1.0.0-2 or later, which reportedly contains the fix. - Until upgraded, review HTML reports generated by Pen Drive before opening them in a browser, or open them in a sandboxed browser environment. - If using must-gather archives from untrusted sources, validate the archive content before feeding it to Pen Drive. - Consider opening Pen Drive reports with JavaScript disabled in the browser.
