Title
Coder: User-admin role can reset owner account password
Summary
Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the `PUT /api/v2/users/{user}/password` endpoint authorized only `ActionUpdatePersonal` and did not prevent a `user-admin` from resetting an `owner` account's password. It also did not require the current password when an admin reset another user's password. Exploitation requires the privileged `user-admin` role so practical risk is limited to deployments that grant `user-admin` to less trusted operators. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 prevents non-owner users from resetting the password of an account that holds the `owner` role. As a workaround, restrict the `user-admin` role to trusted administrators.
