description

OpenStack Mistral deployments through 23.0.0 are affected when the std.ssh_proxied action is enabled. An authenticated project member can cause commands to run on an executor host with the Mistral executor service account's privileges.

mitigation

Disable or restrict access to the std.ssh_proxied action until updates can be applied. Upgrade Mistral to 20.1.1, 21.0.1, or 22.0.1, as appropriate for the deployed release branch.

fixed in 20.1.1, 21.0.1, 22.0.1
