CVE-2026-68563
Description
A flaw was found in ansible-collection-redhat-leapp. When a remediation task is executed with elevated privileges and the leapp_old_postgresql_data option is selected, a PostgreSQL data backup archive is created with insecure permissions. This allows a local non-root user on the managed node to read sensitive archived PostgreSQL data, leading to information disclosure.
Statement
There's a Moderate flaw in ansible-collection-redhat-leapp allows local non-root users to read archived PostgreSQL data. The vulnerability occurs when a specific Leapp remediation task, intended to back up and remove old PostgreSQL data, creates a world-readable archive in /var/backups. Exploitation requires local access to a managed node where this particular remediation workflow has been executed and /var/lib/pgsql/data existed.
Mitigation
To mitigate this issue, ensure that the directory used for PostgreSQL data backups and the resulting archive have restrictive permissions. Administrators should configure their Ansible playbooks or manually adjust permissions to ensure the backup directory (e.g., `/var/backups/leapp`) is owned by root with `0700` permissions, and the backup archive itself has `0600` permissions. This prevents unauthorized local users from accessing sensitive PostgreSQL data. If the current task must be used as-is, restrict local-user access on affected systems and remove or re-permission the generated backup archive immediately after it is created. Always warn if there is a potential for reload and restarts.
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
Technical Impact: Read Application Data; Read Files or Directories
An attacker may be able to read sensitive information from the associated resource, such as credentials or configuration information stored in a file.
Access Control
Technical Impact: Gain Privileges or Assume Identity
An attacker may be able to modify critical properties of the associated resource to gain privileges, such as replacing a world-writable executable with a Trojan horse.
Integrity,Other
Technical Impact: Modify Application Data; Other
An attacker may be able to destroy or corrupt critical data in the associated resource, such as deletion of records from a database.
