SCA: security update for @tinacms/cli (GHSA-rgr9-r7mj-mf6x)

medium Tenable Cloud Security Plugin ID 446212

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 2.5.2, the TinaCMS CLI package's Vite dev server
 packages/@tinacms/cli/src/next/vite/cors.ts origin callback returns false for a disallowed origin but does
 not reject the request, and packages/@tinacms/cli/src/next/vite/plugins.ts still routes POST
 /media/upload/* to mediaRouter.handlePost. The upload code in packages/@tinacms/cli/src/next/commands/dev-
 command/server/media.ts writes attacker-controlled multipart contents inside the configured media root. A
 remote attacker can cause a developer's browser to submit this state-changing request by inducing the
 developer to visit an attacker-controlled page while tinacms dev is running. This issue is fixed in
 version 2.5.2. (CVE-2026-63123)

Solution

Update the @tinacms/cli library and its related packages to version 2.5.2 or later.
