High (7.1) in red hat. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.
On this page
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.

Red Hat
Red Hat rates this Important.
Red Hat Product Security has rated this vulnerability with an Important security impact, affecting smart_proxy_dynflow's task console access handling.
Confidentiality is high. Job inputs are shown with no redaction, including the script and any SSH password, key passphrase, or effective-user password that was set. Integrity is low. Task state can be changed through cancel, resume, and skip. Resume and skip apply only to a paused task.
Red Hat is not aware of a practical temporary workaround that fully mitigates this issue or meets Red Hat Product Security's standards for usability, deployment, applicability, or stability. Customers are advised to apply the relevant security updates when they become available.
