# CVE-2026-59079: Unrestricted File Upload in Edito CMS

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

Edito CMS restricts the ability to upload files via the UI to specific file types. However, an avatar upload functionality allows an attacker to upload files of any type and extension without restriction.
This issue was fixed in version 5.10.2607.  Hotfixes for older versions (5.8) have also been released.
