Detailsinfo

A vulnerability was found in Laravel-Backpack CRUD up to 6.8.13/7.0.37. It has been declared as problematic. Affected by this vulnerability is the function withFiles. The manipulation with an unknown input leads to a unrestricted upload vulnerability. The CWE definition for the vulnerability is CWE-434. The product allows the attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, HasUploadFields methods uploadFileToDisk and uploadMultipleFilesToDisk, used through CrudTrait, and the withFiles() path through FileNameGenerator do not internally reject server-executable file types. An authenticated administrator can achieve remote code execution by using an upload-enabled CRUD field without mimes: and mimetypes: validation when the public disk is web-accessible through php artisan storage:link and the web-server and PHP-FPM configuration executes the stored extension. The legacy path preserves an accepted extension and the newer path derives an extension without blocking dangerous types. The package-level restriction is defense in depth and does not replace application-level upload validation. This issue is fixed in versions 6.8.14 and 7.0.38.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-54177 since 06/11/2026. The exploitation appears to be easy. The attack can be launched remotely. Additional levels of successful authentication are required for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1608.002 for this issue.

Upgrading to version 6.8.14 or 7.0.38 eliminates this vulnerability.
