{"id":"GHSA-m4gq-x24j-jpmf","summary":"Prototype pollution vulnerability found in Mermaid's bundled version of DOMPurify","details":"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.\n\nThis affects the built:\n\n- `dist/mermaid.min.js`\n- `dist/mermaid.js`\n- `dist/mermaid.esm.mjs`\n- `dist/mermaid.esm.min.mjs`\n\nThis 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`\n\n**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`.**\n\n### Patches\n\n- `develop` branch: 6c785c93166c151d27d328ddf68a13d9d65adc00\n- backport to v10: 92a07ffe40aab2769dd1c3431b4eb5beac282b34","modified":"2024-10-23T14:24:24Z","published":"2024-10-22T18:17:02Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-10-22T18:17:02Z","nvd_published_at":null,"cwe_ids":["CWE-1321","CWE-1395"]},"references":[{"type":"WEB","url":"https://github.com/cure53/DOMPurify/security/advisories/GHSA-mmhx-hmjr-r674"},{"type":"WEB","url":"https://github.com/mermaid-js/mermaid/security/advisories/GHSA-m4gq-x24j-jpmf"},{"type":"WEB","url":"https://github.com/mermaid-js/mermaid/commit/6c785c93166c151d27d328ddf68a13d9d65adc00"},{"type":"WEB","url":"https://github.com/mermaid-js/mermaid/commit/92a07ffe40aab2769dd1c3431b4eb5beac282b34"},{"type":"PACKAGE","url":"https://github.com/mermaid-js/mermaid"}],"affected":[{"package":{"name":"mermaid","ecosystem":"npm","purl":"pkg:npm/mermaid"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"10.9.3"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 10.9.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/10/GHSA-m4gq-x24j-jpmf/GHSA-m4gq-x24j-jpmf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:L"}]}
