# CVE-2026-119708: abp-next-admin 10.4.0 through 10.7.0 Cross-Tenant File Disclosure via Blob Download-By-Name

Status: published. Published: 2026-10-30. Updated: 2026-11-05.

abp-next-admin 10.4.0 through 10.7.0 contains a cross-tenant authorization bypass in the BlobManagement download-by-name endpoint, letting authenticated users read other tenants' files. Attackers supply a victim tenantId in the request path, causing DownloadByNameAsync to switch tenant context and return blobs stored by that tenant.
