Affected versions of the link plugin and link UI component do not sanitize URLs to prevent use of the `javascript:` scheme. As a result, links with JavaScript URLs can be inserted into the Plate editor through various means, including opening or pasting malicious content. `@udecode/plate-link` 20.0.0 resolves this issue by introducing an `allowedSchemes` option to the link plugin, defaulting to `['http', 'https', 'mailto', 'tel']`. URLs using a scheme that isn't in this list will not be rendered to the DOM. Users are advised to upgrade. Users unable to upgrade are advised to override the `LinkElement` and `PlateFloatingLink` components with implementations that explicitly check the URL scheme before rendering any anchor elements.","published":"2023-06-09T18:15:10.000Z","lastModified":"2026-06-17T06:03:13.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":["udecode/plate"],"epss":{"score":0.00445,"percentile":0.38517,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.45%).
