Summary: The Filament project has issued a critical security advisory for a Cross-Site Scripting (XSS) vulnerability, CVE-2024-47186, affecting versions 3.0.0 to 3.2.114. This vulnerability allows attackers to execute malicious scripts through improperly validated color values, posing a significant risk to applications using the framework.
Threat Actor: Unknown | unknown
Victim: Filament project | Filament project
Key Point :
- The vulnerability allows attackers to inject scripts via unvalidated ColorColumn or ColorEntry values.
- Security researcher @sv-LayZ disclosed the vulnerability responsibly, prompting a swift response from the Filament team.
- Developers are urged to upgrade to version 3.2.115 and follow best practices for input validation.
- Additional documentation on color validation has been provided to help secure applications further.
The Filament project, a popular collection of full-stack components for accelerated Laravel development, has issued a critical security advisory for CVE-2024-47186. This Cross-Site Scripting (XSS) vulnerability affects versions from v3.0.0 to v3.2.114, posing a significant risk to applications that render unvalidated ColorColumn or ColorEntry values.
CVE-2024-47186 is a critical XSS vulnerability caused by improper validation of values passed to the ColorColumn and ColorEntry components. If an invalid color value containing a specific set of characters is supplied, attackers can execute malicious scripts on the application page where the color column or entry is rendered. This could result in unauthorized actions, data theft, or other harmful consequences for users who interact with the affected web pages.
XSS attacks exploit weaknesses in how web applications handle untrusted input, allowing attackers to inject client-side scripts. These scripts can be used to steal session tokens, manipulate web content, or redirect users to malicious websites. Given the widespread use of Filament in Laravel development, this vulnerability represents a significant threat to websites and applications relying on the framework.
Security researcher @sv-LayZ is credited with responsibly disclosing the vulnerability, allowing the Filament team to address the issue before malicious actors could exploit it. Although a proof of concept (PoC) for the vulnerability will be published in the coming weeks, developers are urged to upgrade their applications immediately to prevent possible exploitation.
Filament developers have responded swiftly by releasing version 3.2.115, which mitigates the vulnerability by validating ColorColumn and ColorEntry values. However, developers must continue following best practices, particularly by validating all user inputs. Since many Filament users accept color input using the ColorPicker form component, the Filament team has also published additional color validation documentation to assist developers in further securing their applications.
