  "title": "rhc-worker-playbook: A local privilege escalation vulnerability was found in the ansible.posix authorized_key module",
  "description": "A local privilege escalation vulnerability was found in the ansible.posix authorized_key module. The module\u0027s keyfile() function uses os.chown() instead of os.lchown() and opens files without O_NOFOLLOW when managing SSH authorized keys. An unprivileged local user can pre-stage symbolic links in their ~/.ssh directory to redirect file ownership changes to arbitrary system paths when an operator runs the authorized_key task as root, leading to local privilege escalation.",
