CVE-2023-28536Network attack vector

Unauthenticated modification of access-controlled data

Published Dec 9, 2024 · Updated Apr 28, 2026

Missing authorization in Acato Branded Social Images 1.1.0 and earlier allows remote attackers to modify access-controlled data. Neither the CNA record, its sole Patchstack reference, nor the upstream 1.1.1 changelog discloses the affected handler or the authorization check it omits. Exploitation requires network access but no authentication or user interaction, and the published impact is limited to data integrity.
