Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven, npm, NuGet packages — download data is not available via public APIs for these ecosystems.

Description

Impact

Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches

This problem is patched in jQuery 3.5.0.

Workarounds

To workaround this issue without upgrading, use DOMPurify with its SAFE_FOR_JQUERY option to sanitize the HTML string before passing it to a jQuery method.
