Title
Corteza through 2024.9.10 Unauthenticated Attachment Access via Compose Attachment Endpoints
Summary
Corteza through 2024.9.10 contains an incorrect authorization vulnerability in compose attachment endpoints that allows unauthenticated attackers to download private attachments by setting the URL kind segment to page, icon, or namespace. Attackers who know a private record or module attachment id can request the original or preview route without a token or signature to retrieve files across namespace and record permission boundaries.
