SCA: security update for @tinacms/cli (GHSA-2f24-mg4x-534q)

high Tenable Self-Hosted Container Security Plugin ID 438750

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Tina is a headless content management system. Prior to 2.1.8, the TinaCMS CLI development server exposes
 media endpoints that are vulnerable to path traversal, allowing attackers to read and write arbitrary
 files on the filesystem outside the intended media directory. When running tinacms dev, the CLI starts a
 local HTTP server (default port 4001) exposing endpoints such as /media/list/*, /media/upload/*, and
 /media/*. These endpoints process user-controlled path segments using decodeURI() and path.join() without
 validating that the resolved path remains within the configured media directory. This vulnerability is
 fixed in 2.1.8. (CVE-2026-28793)

Solution

Update the @tinacms/cli library and its related packages to version 2.1.8 or later.
