# CVE-2026-107152: Rubygem-smart_proxy_dynflow: dynflow console authorizes any client certificate the capsule ca signed

Status: published. Published: 2026-11-12. Updated: 2026-11-12.

An improper authentication vulnerability has been found in the task console in the smart_proxy_dynflow package. The console accepts any client certificate signed by the capsule's certificate authority. It does not check the list of servers the capsule trusts. A low-privileged network attacker or user must already hold such a certificate. They can open the console and read job details. Those details include passwords when a job was given them. They can also cancel a running task.
