Unauthenticated file disclosure via anonymous preview routes
Published Sep 18, 2026 · Updated Sep 18, 2026
Missing authorization in Cordys CRM before 1.7.4 allows remote attackers to download cross-organization files through preview routes. ShiroFilter marks /attachment/preview/{id} and /pic/preview/{id} anonymous, while AttachmentService.getResource uses the supplied ID in a primary-key lookup without ownership, organization, or permission checks. An attacker needs only a guessed or observed generated ID to read files uploaded by users in other organizations.
