Vulnerability from cvelistv5 – Published: 2026-07-30 16:45 – Updated: 2026-07-30 17:32

Title

Langflow is affected by path traversal due to multiple unauthenticated and insufficiently authorized API endpoints

Summary

IBM Langflow OSS 1.0.0 through 1.10.1 could allow a remote attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot " sequences ( /.. /) to view arbitrary files on the system.

Severity

7.5 (High)
