Summary
A flaw was found in ansible-collection-redhat-leapp. An attacker with privileged write access to a managed node's Leapp report content can manipulate it.
When an operator runs a specific remediation task, this manipulated report can cause the Ansible controller to read its own local files and copy them to the managed node. This vulnerability leads to information disclosure, potentially exposing sensitive controller-side data such as private keys or credentials.
When an operator subsequently runs the `leapp_corrupted_grubenv_file` remediation, the Ansible controller may be tricked into disclosing sensitive controller-local files to the compromised managed node, crossing a trust boundary. Exploitation depends on both prior compromise of the managed node and specific operator action.

Mitigation checklist
- To mitigate this issue, avoid running the `leapp_corrupted_grubenv_file` remediation against managed nodes whose Leapp report content is not trusted. As a local hardening measure, modify the relevant Ansible playbook to explicitly set `remote_src: true` for `ansible.builtin.copy` tasks within the `leapp_corrupted_grubenv_file` role. Additionally, implement path validation to ensure that `src` paths are strictly confined to the expected `/boot` subtree. These changes require re-execution of the Ansible playbook to take effect.
