CVE-2026-5135
Unauthorized modification of host configurations via broken access control.
When lookup values are submitted as nested attributes during host or hostgroup updates, the match field is permitted and applied without ownership validation. A user with host-edit rights can retarget an existing lookup value override to point at a different host, injecting configuration values into hosts they are not authorized to edit.
