CVE-2026-118542: Incorrect Authorization vulnerability in Drupal Commerce Core allows Forceful Browsing. This issue affects Commerce Core versions: from 0.0.

CVE-2026-118542 · Severity: info · Published 2026-10-30

Drupal Commerce Core is an e-commerce module that allows sites to sell goods and services with shopping cart and checkout functionality, often used by marketplace platforms where vendors manage their own stores. An attacker with store creation or editing permissions can manipulate the saved store data to mark their store as the site's default, causing them to receive orders they should not have access to. This is particularly dangerous on marketplace sites that grant these permissions to untrusted vendor users.

Technical details

An access bypass vulnerability exists in the store save functionality where insufficient permission checks allow a user with create or edit store permissions to elevate a store to default status without proper authorization. The vulnerability requires the attacker to already possess store-level permissions (either create any store or edit their own store). An authenticated attacker can redirect orders intended for other stores to their own account.
