What is CVE-2026-81658?

CVE-2026-81658 is a medium-severity missing authorization vulnerability in Redhat Satellite, published on 27 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

A flaw was found in Foreman. The template revision endpoint does not enforce object-level authorization when retrieving an audited template revision. An authenticated, low privileged user with a template-related permission, such as view_ptables, can obtain historical template contents belonging to another organization or location by supplying the corresponding audit ID. This can result in unauthorized disclosure of historical template contents, which may contain sensitive configuration information, credentials, or other secrets. The REST API revision endpoints correctly restrict this lookup.
