# paopao-ce: authenticated users can download other users' private media

Paopao-ce through 0.6.0-alpha.3 lets any logged-in user request attachments by arbitrary content ID through the /v1/attachment endpoint. An attacker can enumerate sequential IDs and get signed download URLs for other users' private, friend-only and following-only images, videos and files.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed paopao-ce version; `unknown` whether the sources name the exact file or line to inspect
- Confirm whether `/v1/attachment` is reachable on your deployment with a normal user account

## Fix

- Upgrade paopao-ce past `0.6.0-alpha.3`; `unknown` which release contains the patch
- Until patched, restrict or disable the `/v1/attachment` route for non-owners if possible

## From the sources

Rocboss paopao-ce through 0.6.0-alpha.3 contains an insecure direct object reference vulnerability in DownloadAttachment that allows authenticated users to access private media by supplying arbitrary content IDs. Attackers can enumerate sequential post_content ids via the /v1/attachment endpoint to obtain signed download URLs for other users' private, friend-only and following-only images, videos and attachments.
