DRUPAL-CONTRIB-2026-323: Composer/drupal/commerce_license vulnerability

Q: Which deployments are exposed to this issue?

Deployments are exposed when JSON:API or REST is configured to allow writes to order items. This is not the default configuration.

Q: What does an attacker need to do to exploit it?

An attacker needs the ability to write order items through JSON:API or REST. The insufficient validation can then allow the attacker to take over another user's license.

Q: What should be reviewed if patching cannot happen immediately?

Review JSON:API and REST configuration for permissions or endpoints that allow order-item writes, and remove or restrict that write access where it is not required.

Updated

This module enables you to sell licenses that grant access to resources (such as roles) through Drupal Commerce.

The module doesn't sufficiently validate the license referenced by an order item, allowing an attacker to take over another user's license.

This vulnerability is mitigated by the fact that JSON:API or REST must be configured to allow writes to order items, which is not the default.
