Privilege Escalation Vulnerability in Craft CMS by Pixel & Tonic
CVE-2026-50284
What is CVE-2026-50284?
Craft CMS, developed by Pixel & Tonic, has a security vulnerability stemming from improper permission checks during asset deletion operations. Specifically, the AssetsController::actionDeleteFolder() mistakenly permits a low-privilege user with folder-management rights to delete not just their own assets but also those uploaded by peers, thus bypassing the intended per-asset permission controls. This flaw exists in multiple versions of Craft CMS, and it poses a significant risk of asset loss within shared volumes. The vulnerability has been resolved in subsequent updates, specifically versions 4.17.15 and 5.9.22, which enforce the necessary permissions for enhanced security.
