CVE-2025-52554
Prior to version 1.99.1, an authorization vulnerability was discovered in the /rest/executions/:id/stop endpoint of n8n.
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
Description
n8n is a workflow automation platform. Prior to version 1.99.1, an authorization vulnerability was discovered in the /rest/executions/:id/stop endpoint of n8n. An authenticated user can stop workflow executions that they do not own or that have not been shared with them, leading to potential business disruption. This issue has been patched in version 1.99.1. A workaround involves restricting access to the /rest/executions/:id/stop endpoint via reverse proxy or API gateway.
