Title
Path Traversal Vulnerability in API Request Component Content-Disposition Header Processing
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 allows an authenticated attacker to create a malicious flow pointing to an attacker-controlled URL that returns a specially crafted Content-Disposition header (e.g., filename="../../../target/path" ), enabling arbitrary file write operations with attacker-controlled content to any path accessible by the Langflow process.
