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.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-06-09 18:15:00","updated_at":"2023-06-21 18:37:00"},"problem_types":["CWE-79"],"metrics":[],"references":[{"url":"https://github.com/udecode/plate/security/advisories/GHSA-4882-hxpr-hrvm","name":"https://github.com/udecode/plate/security/advisories/GHSA-4882-hxpr-hrvm","refsource":"MISC","tags":[],"title":"Links may contain URLs with JavaScript scheme · Advisory · udecode/plate · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/udecode/plate/commit/93dd5712854660874900ae12e4d8e6ff28089eb7","name":"https://github.com/udecode/plate/commit/93dd5712854660874900ae12e4d8e6ff28089eb7","refsource":"MISC","tags":[],"title":"Apply isUrl option to pasted links #2239 (#2240) · udecode/plate@93dd571 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-34245","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34245","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"34245","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"udecode","cpe5":"plate","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-34245","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"@udecode/plate-link is the link handler for the udecode/plate rich-text editor plugin system for Slate & React.
