- Summary
- Cross-Site Scripting in dompurify
- Details
-
Versions of
dompurifyprior to 2.0.3 are vulnerable to Cross-Site Scripting (XSS). The package has an XSS filter bypass due to Mutation XSS in both Chrome and Safari through a combination of<svg>/<math>elements and</p>/</br>. An example payload is:<svg></p><style><a id="</style><img src=1 onerror=alert(1)>">. This allows attackers to bypass the XSS protection and execute arbitrary JavaScript in a victim's browser.Recommendation
Upgrade to version 2.0.3 or later. You may also disallow
<svg>and<math>throughdompurifyconfigurations:DOMPurify.sanitize(input, { FORBID_TAGS: ['svg', 'math'] }); - Database specific
