CVE-2026-48500: CWE-862: Missing Authorization in filamentphp filament
A missing authorization vulnerability in filamentphp's Filament allows unauthenticated attackers to upload arbitrary files to temporary storage via certain components that do not require file uploads, such as the panel login form. This can lead to resource exhaustion or increased storage costs. The issue affects versions from 3.0.0 up to but not including 3.3.52, 4.11.5, and 5.6.5, where it has been fixed.
AI Analysis
Technical Summary
Filament, a Laravel full-stack component collection, applies Livewire's WithFileUploads trait to components containing file upload fields. However, some schemas like the panel login form do not need file uploads but still expose unauthenticated temporary file upload functionality. This missing authorization (CWE-862) allows unauthenticated attackers to upload arbitrary files to temporary storage, potentially exhausting disk space or inflating storage costs. The vulnerability is fixed in versions 3.3.52, 4.11.5, and 5.6.5.
Potential Impact
Unauthenticated attackers can upload arbitrary files to the application's temporary storage on vulnerable versions, leading to denial of service through disk space exhaustion or increased storage costs. There is no direct confidentiality impact, but integrity and availability are affected.
Mitigation Recommendations
This vulnerability is fixed in Filament versions 3.3.52, 4.11.5, and 5.6.5. Users should upgrade to these or later versions to remediate the issue. No vendor advisory is provided to indicate alternative mitigations or temporary fixes.
