An insecure direct object reference vulnerability has been identified in Rocboss PaoPao-Ce versions through 0.6.0-alpha.3. This vulnerability allows authenticated users to access private media by supplying arbitrary content IDs via the DownloadAttachment endpoint. Attackers can enumerate post_content IDs to obtain signed download URLs for other users' private, friend-only, and following-only images, videos, and attachments.
The vulnerability can be fixed by enforcing visibility checks for all content types in the DownloadAttachment handler, ensuring that only authorized users can access the requested media. This involves loading the parent post for each content ID and applying the same visibility rules already used in the TweetDetail endpoint.
