CVE-2026-56097 is an SQL injection vulnerability in rubygem-katello's Red Hat Satellite Katello Registry Proxy. The RegistryProxiesController methods check_blob_push_org_label and get_matching_products_from_org interpolate user-supplied labels from request paths into raw SQL fragments without adequate sanitization. A user possessing only the create_personal_access_tokens permission can reach the vulnerable functionality, even when the account has restricted access and no assigned Organization or Location.
