Detailsinfo

A vulnerability was found in Red Hat Satellite (version unknown). It has been declared as problematic. This vulnerability affects the function Foreman::Controller::UserAware#find_user of the component SshKeysController. The manipulation of the argument user_id with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. As an impact it is known to affect integrity. CVE summarizes:

A flaw was found in Foreman’s Api::V2::SshKeysController, where the target user is resolved through Foreman::Controller::UserAware#find_user using User.find(params[:user_id]) without enforcing the required parent-user authorization check. An attacker with the create_ssh_keys permission can exploit this authorization bypass by submitting POST /api/v2/users/:user_id/ssh_keys with another user’s ID and injecting their own public SSH key into the targeted account. The injected key is subsequently propagated to hosts provisioned by that user, potentially allowing the attacker to authenticate to and gain SSH access to the victim’s managed hosts.

The advisory is available at access.redhat.com. This vulnerability was named CVE-2026-86324 since 09/07/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 11/12/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
