Published 24 May 2022 · Updated 16 Feb 2024

Affected package

craftcms/cmsComposer

Affected: <3.1.31
Fixed in: 3.1.31

Details

Craft CMS before 3.1.31 does not properly filter XML feeds, thus allowing XSS.

Is GHSA-w5q4-q7wp-qww6 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.

Scan a project free, no signup Or connect GitHub to scan every repo
