CVE-2026-34604: Ssw Tinacms/graphql

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

Tina is a headless content management system. Prior to version 2.2.2, @tinacms/graphql uses string-based path containment checks in FilesystemBridge. That blocks plain ../ traversal, but it does not resolve symlink or junction targets. If a symlink/junction already exists under the allowed content root, a path like content/posts/pivot/owned.md is still considered "inside" the base even though the real filesystem target can be outside it. As a result, FilesystemBridge.get(), put(), delete(), and glob() can operate on files outside the intended root. This issue has been patched in version 2.2.2.

Affected products

• Ssw Tinacms/graphql: up to and including 2.2.1
