Name of the Vulnerable Software and Affected Versions StackStorm versions prior to 2.9.2 StackStorm versions 2.10.x prior to 2.10.1

Description The issue is related to incorrect access control in the StackStorm API, allowing an authenticated attacker with a StackStorm account to retrieve datastore items for other users. This can be achieved by utilizing the /v1/keys API endpoint with specific query filter parameters, such as ?scope=all and ?user=<username>. It is noted that Enterprise editions with RBAC enabled are not affected.

Recommendations For StackStorm versions prior to 2.9.2, update to version 2.9.2 or later. For StackStorm versions 2.10.x prior to 2.10.1, update to version 2.10.1 or later. As a temporary workaround, consider restricting access to the /v1/keys API endpoint to minimize the risk of exploitation. Avoid using the scope and user query filter parameters in the affected API endpoint until the issue is resolved.
