GHSA-592m-4533-rxq9
SilverStripe Folders migrated from 3.x may be unsafe to upload to
Quick fix
GHSA-592m-4533-rxq9 — silverstripe/framework: upgrade to the fixed version with the command below.
composer require silverstripe/framework:^4.4.6Details
In SilverStripe through 4.5, files uploaded via Forms to folders migrated from Silverstripe CMS 3.x may be put to the default "/Uploads" folder instead. This affects installations which allowed upload folder protection via the optional silverstripe/secureassets module under 3.x. This module is installed and enabled by default on the Common Web Platform (CWP). The vulnerability only affects files uploaded after an upgrade to 4.x.
