Description

Tinacms is a Git-backed headless content management system with support for visual editing. Sites being built with @tinacms/cli >= 1.0.0 && < 1.0.9 which store sensitive values in the process.env variable are impacted. These values will be added in plaintext to the index.js file. If you're on a version prior to 1.0.0 this vulnerability does not affect you. If you are affected and your Tina-enabled website has sensitive credentials stored as environment variables (eg. Algolia API keys) you should rotate those keys immediately. This issue has been patched in @tinacms/cli@1.0.9. Users are advised to upgrade. There are no known workarounds for this issue.

Affected products

tinacms: from 1.0.0 before 1.0.9 — fixed in 1.0.9

How to fix

Upgrade to a fixed version: tinacms 1.0.9. Check the vendor advisory for mitigations.
