Langflow: /profile_pictures/{folder_name}/{file_name} endpoint file reading

Assigner: GitHub_M
Reserved: 20.03.2026 Published: 24.03.2026 Updated: 24.03.2026

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.1, in the download_profile_picture function of the /profile_pictures/{folder_name}/{file_name} endpoint, the folder_name and file_name parameters are not strictly filtered, which allows the secret_key to be read across directories. Version 1.7.1 contains a patch.
