CVE-2026-5138
Information disclosure via improper validation of nested request parameters.
The
taxonomy_scopecontroller method loads organization and location IDs from nested request parameters without checking the user's taxonomy membership. An authenticated user with host-edit permissions can supply a foreign organization ID in nested parameters to scope AJAX queries to a tenant they do not belong to, leaking infrastructure metadata such as domains, subnets, and IP availability.
