{"id":"CVE-2026-88976","published":"2026-09-16T15:18:05.850","lastModified":"2026-09-16T16:17:20.227","description":"Plate is a rich-text editor with AI and shadcn/ui. Prior to 53.3.11, and in the discontinued 54.0.0-beta.0 through 54.0.0-beta.1 builds, Plate core HTML deserialization APIs parse supplied HTML strings in the active document. When an application passes untrusted or cross-user HTML to these APIs, certain HTML attributes can trigger browser behavior before the HTML is converted into editor nodes. This can allow attacker-controlled script to execute in the consuming application's origin when another user loads the deserialized content. This issue is fixed in version 53.3.11.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/udecode/plate/commit/d02afe45d5ec3a9fb95e0745bc5820ff18a3c12b","tags":[]},{"url":"https://github.com/udecode/plate/pull/5117","tags":[]},{"url":"https://github.com/udecode/plate/releases/tag/v53.3.11","tags":[]},{"url":"https://github.com/udecode/plate/security/advisories/GHSA-qrfj-mgw8-j9c6","tags":[]}],"exploitRefs":[{"url":"https://github.com/udecode/plate/commit/d02afe45d5ec3a9fb95e0745bc5820ff18a3c12b","tags":[]},{"url":"https://github.com/udecode/plate/pull/5117","tags":[]},{"url":"https://github.com/udecode/plate/releases/tag/v53.3.11","tags":[]},{"url":"https://github.com/udecode/plate/security/advisories/GHSA-qrfj-mgw8-j9c6","tags":[]}],"hasPoc":true,"ai":null}
