CVE-2026-55409: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in filamentphp filament
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.
AI Analysis
Technical Summary
Filamentphp filament versions >=3.0.0 and <3.3.53 contain a CWE-79 improper neutralization of input vulnerability. Specifically, a disabled RichEditor field outputs its raw state without HTML sanitization. If the form state data is not sanitized before being stored, an attacker can inject malicious HTML or JavaScript, leading to cross-site scripting (XSS) that executes in the context of users viewing the affected form. The vulnerability is resolved in version 3.3.53.
Potential Impact
Successful exploitation allows an attacker with limited privileges (PR:L) and requiring user interaction (UI:R) to execute arbitrary HTML or JavaScript in the context of other users viewing the form. This can lead to high confidentiality impact by exposing sensitive information, with limited integrity impact and no availability impact. The vulnerability affects confidentiality and user trust.
Mitigation Recommendations
Upgrade filamentphp filament to version 3.3.53 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the version boundary provided.
