CVE-2026-88976

CVE-2026-88976 · @platejs/core HTML deserialization can trigger browser behavior during parsing

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
