Attack-Flow Graph

Executive Summary

This vulnerability exists in IBM Langflow Desktop versions 1.0.0 through 1.8.4. It allows an unauthenticated user to view images belonging to other users. This happens because of an indirect object reference issue, where a user-controlled key can be manipulated to access images that should not be accessible.

Impact Analysis

The vulnerability can lead to unauthorized disclosure of sensitive or private images since an attacker does not need to authenticate to view other users' images. This can result in a loss of confidentiality and potentially harm user privacy.
