CVE-2026-55409 Details
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.
A cross-site scripting (XSS) vulnerability has been identified in Filament versions 3.0.0 prior to 3.3.53. The issue arises in the RichEditor component when it is disabled; the editor renders its raw state without properly sanitizing HTML. If the data in this field is not already sanitized when the form is loaded, an attacker could inject malicious HTML or JavaScript. This injected script would execute for users who view the form.
Users can upgrade to Filament version 3.3.53 or later to address this vulnerability. Note that Filament version 4 and above does not use the same rendering mechanism for a disabled RichEditor, so this advisory is not applicable to those versions.
