View online: https://www.drupal.org/sa-contrib-2026-257 Project: Commerce Core [1] Project machine name: commerce Date: 2026-October-27 Security risk: *Moderately critical* 10 ∕ 25 AC:Basic/A:Admin/CI:None/II:Some/E:Theoretical/TD:All [2] Vulnerability: Access bypass Affected versions: <2.41.0 || >=3.0.0 <3.3.13 CVE IDs: CVE-2026-118542 Description: This module enables you to sell goods and services to customers through a shopping cart and checkout form. Sites can also create multiple online stores that are managed by different users. The module doesn't check access properly when a store is saved. A user who can either create stores or edit their own store is able to mark their store as the site's default store. This causes their store to get some orders they normally shouldn't. Only sites that give those permissions to untrusted users are affected (for example, marketplace sites where vendors manage their own stores). Solution: Install the latest version: * If you use version 3.x, upgrade to Commerce Core 3.3.13 [3]. * If you use an earlier version, upgrade to Commerce Core 8.x-2.41 [4].
