CVE-2026-86324 · Severity: medium · CVSS 4.3 · Published 2026-11-12

Foreman is an open-source infrastructure management platform that provisions and manages hosts across an organization. An attacker with SSH key creation permissions can bypass authorization checks to inject their own SSH keys into other users' accounts, potentially gaining unauthorized SSH access to all hosts provisioned by victims. This lateral privilege escalation affects users who rely on Foreman to manage their server infrastructure.

## Technical details

The Api::V2::SshKeysController in Foreman resolves the target user via User.find(params[:user_id]) without enforcing parent-user authorization checks, creating a CWE-639 authorization bypass. An authenticated attacker with create_ssh_keys permission can POST to /api/v2/users/:user_id/ssh_keys with an arbitrary user ID to inject their public key into another account; the key is then propagated to that user's provisioned hosts, enabling SSH access.
