Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Critters versions 0.0.17-0.0.19 have an issue when parsing the HTML, which leads to a potential cross-site scripting (XSS) bug. We recommend upgrading to version 0.0.20 of the extension.
