CVE-2026-68562
Description
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.
Statement
This Moderate severity flaw in ansible-collection-redhat-leapp allows an attacker with privileged write access on a managed node to tamper with Leapp report content. 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
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality,Integrity
Technical Impact: Read Application Data; Modify Application Data
An adversary could read or modify data, depending on how the resource is intended to be used.
Access Control
Technical Impact: Gain Privileges or Assume Identity
An adversary that can supply a reference to an unintended resource can potentially access a resource that they do not have privileges for, thus bypassing existing access control mechanisms.
