Details

Impact

Similar to another advisory, certain additional PHP files crafted to look like images may be uploaded regardless of mime type validation rules. This affects front-end forms using the "Forms" feature, and asset upload fields in the control panel.

Patches

It has been patched in 3.4.14 and 4.34.0.

Is GHSA-2r53-9295-3m86 in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected statamic/cms, and gives you the command that fixes it.
