Craft CMS PHP Code Injection Vulnerability

Published 13 May 2022 · Updated 25 Apr 2024

Affected package

craftcms/cmsComposer
Affected
<=2.6.3000
Fixed in
No fix released

Details

Craft CMS 2.6.3000 allows remote attackers to execute arbitrary PHP code by using the "Assets->Upload files" screen and then the "Replace it" option, because this allows a .jpg file to have embedded PHP code, and then be renamed to a .php extension.

Is GHSA-r342-vjc4-wrmj 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 craftcms/cms, and gives you the command that fixes it.
