Overview

CVE-2026-34604 is a high-severity vulnerability. It was published on April 1, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
