Description

Tina is a headless content management system. In tinacms prior to version 3.1.1, tinacms uses the gray-matter package in an insecure way allowing attackers that can control the content of the processed markdown files, e.g., blog posts, to execute arbitrary code. tinacms version 3.1.1, @tinacms/cli version 2.0.4, and @tinacms/graphql version 2.0.3 contain a fix for the issue.

Affected products

Ssw Tinacms: before 3.1.1 — fixed in 3.1.1

@tinacms graphql: before 2.0.3 — fixed in 2.0.3

How to fix

Upgrade to a fixed version: Ssw Tinacms 3.1.1; tinacms 2.0.4; @tinacms graphql 2.0.3. Check the vendor advisory for mitigations.
