Details

Cross-Site Scripting in sanitize-html Affected versions of `sanitize-html` are vulnerable to cross-site scripting when allowedTags includes at least one `nonTextTag`. ## Proof of Concept ```js var sanitizeHtml = require('sanitize-html'); var dirty = '!<textarea>&lt;/textarea&gt;<svg/onload=prompt`xs`&gt;</textarea>!'; var clean = sanitizeHtml(dirty, { allowedTags: [ 'textarea' ] }); console.log(clean); // !<textarea></textarea><svg/onload=prompt`xs`></textarea>! ``` ## Recommendation Update to version 1.11.4 or later.
