PyPI: langflow
CVE-2026-33497
Safety vulnerability ID: SFTY-20260320-94626
Safety legacy ID: pyup.io-90208
Affected versions of the langflow package are vulnerable to Path Traversal due to improper sanitization of user-controlled path parameters. The download_profile_picture function in the /profile_pictures/{folder_name}/{file_name} endpoint does not strictly filter the folder_name and file_name parameters, allowing path elements such as .. to escape the intended directory and access sensitive files, including the secret_key.
