CVE-2020-9280
This affects installations which allowed upload folder protection via the optional silverstripe/secureassets module under 3.x.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
