Description

Statmic is a core Laravel content management system Composer package. Prior to versions 3.4.13 and 4.33.0, on front-end forms with an asset upload field, PHP files crafted to look like images may be uploaded. This only affects forms using the "Forms" feature and not just _any_ arbitrary form. This does not affect the control panel. This issue has been patched in 3.4.13 and 4.33.0.

Affected products

• Statamic: before 3.4.13; from 4.0.0 before 4.33.0 — fixed in 3.4.13, 4.33.0

How to fix

Upgrade to a fixed version: Statamic 3.4.13, 4.33.0. Check the vendor advisory for mitigations.
