    Title
    Semaphore UI through 2.19.16 RCE via Task Environment Ansible Variable Override
    Summary
    Semaphore UI through 2.19.16 contains a remote code execution vulnerability that allows users with the task_runner role to override protected Ansible variables by supplying arbitrary keys in the task environment JSON.
