GHSA-m4gq-x24j-jpmf
Prototype pollution vulnerability found in Mermaid's bundled version of DOMPurify
Quick fix
GHSA-m4gq-x24j-jpmf — mermaid: upgrade to the fixed version with the command below.
npm install mermaid@10.9.3Details
The following bundled files within the Mermaid NPM package contain a bundled version of DOMPurify that is vulnerable to https://github.com/cure53/DOMPurify/security/advisories/GHSA-mmhx-hmjr-r674, potentially resulting in an XSS attack.
This affects the built:
- `dist/mermaid.min.js` - `dist/mermaid.js` - `dist/mermaid.esm.mjs` - `dist/mermaid.esm.min.mjs`
This will also affect users that use the above files via a CDN link, e.g. `https://cdn.jsdelivr.net/npm/mermaid@10.9.2/dist/mermaid.min.js`
**Users that use the default NPM export of `mermaid`, e.g. `import mermaid from 'mermaid'`, or the `dist/mermaid.core.mjs` file, do not use this bundled version of DOMPurify, and can easily update using their package manager with something like `npm audit fix`.**
