What is CVE-2026-113358?

LavaLite CMS versions up to 10.1.2 are vulnerable due to a missing authentication mechanism in the Filer module. This flaw permits unauthorized attackers to exploit the filer/download and filer/display routes, enabling them to download sensitive files stored within the application. By providing arbitrary disk names and paths to the FileController, attackers can access private uploads from both local storage and configured remote S3 disks. Immediate action is recommended to safeguard against potential data breaches.
