What is CVE-2026-86324?

A vulnerability exists in Foreman's SSH key management API, specifically within the Api::V2::SshKeysController. The issue arises from improper parent-user authorization checks during user resolution, allowing attackers with create_ssh_keys permissions to submit requests using arbitrary user IDs. By injecting their own public SSH keys into another user's account, the attacker can gain SSH access to hosts that the victim manages, compromising security and control over the environment.
