DOMPurify allows Cross-site Scripting (XSS)

Published 14 Feb 2025 · Updated 10 Sept 2026

Affected package

Affected: <3.2.4
Fixed in: 3.2.4

Update to the fixed version for your release line, for example:npm install dompurify@3.2.4

Details

DOMPurify before 3.2.4 has an incorrect template literal regular expression when SAFE_FOR_TEMPLATES is set to true, sometimes leading to mutation cross-site scripting (mXSS).

Is GHSA-vhxf-7vqr-mrjg in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected dompurify, and gives you the command that fixes it.
