Filament: Disabled RichEditor field state can be used for XSS

Published Jun 22, 2026 · Updated Nov 3, 2026 · Assigned by GitHub_M

Description

Filament is a collection of full-stack components for accelerated Laravel development. From 3.0.0 until 3.3.53, a disabled RichEditor field rendered its raw state without sanitizing HTML. Where the data stored in this field's state isn't sanitized already when the form state was filled, an attacker could plant malicious HTML or JavaScript and achieve XSS that executes for users who view the form. This vulnerability is fixed in 3.3.53.
