How to Fix CVE-2026-14793

To remediate this vulnerability, upgrade all affected Craft CMS dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

craftcms/cms fixed: 4.18.1
Upgrade craftcms/cms to 4.18.1
craftcms/cms fixed: 5.10.3
Upgrade craftcms/cms to 5.10.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for craftcms/cms

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-14793, inspect your project dependencies for Craft CMS:

inspect dependencies for craftcms/cms

Analyze the terminal output to locate any version of Craft CMS in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.18.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Craft CMS, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The `reorder-sets` action in Craft CMS’s `GlobalsController` is missing the `requireAdmin()` check that the adjacent `save-set` and `delete-set` actions both enforce. Any authenticated control panel user can POST to `/actions/globals/reorder-sets` and permanently reorder all global sets in the project config, regardless of whether they have admin access. The reordering is written through to the project config and persists across requests. ## Description `GlobalsController` exposes three administrative actions for managing global set structure. Two of them gate on admin status; the third does not. ## Prerequisites - A Craft CMS instance with at least two global sets and a non-admin control panel user account. ## Impact A non-admin control panel user can reorder all global sets. While this does not expose or modify content, reordering global sets modifies the project config -- a versioned artifact that is typically committed to source control and deployed across environments. An attacker can create noise in the project config history, trigger config-sync conflicts, or manipulate the display order seen by all editors in the admin panel. The same non-admin user cannot create or delete global sets because those actions correctly enforce `requireAdmin()`.
