InvokeAI has External Control of File Name or Path

Path Traversal Vulnerability in InvokeAI

A path traversal vulnerability in InvokeAI (versions < 6.7.0) allows an unauthenticated remote attacker to read files outside the intended media directory via the bulk downloads API.

The endpoint accepts a user-controlled file/item name and concatenates it into a filesystem path without proper canonicalization or allow-listing. By supplying sequences such as ../ (or absolute paths), an attacker can cause the server to traverse directories and return arbitrary files.

In certain storage or back-end configurations, abusing attacker-controlled paths can also lead to unintended overwriting or deletion of files referenced by the crafted path.

The issue is fixed in 6.7.0, which normalizes and validates input paths and rejects traversal attempts.

Affected versions: < 6.7.0

Patched version: 6.7.0
