CVE-2026-7528 Details
Description
IBM Langflow OSS 1.0.0 through 1.9.0 could allow a denial of service due to uncontrolled resource consumption.
A denial-of-service vulnerability has been identified in IBM Langflow OSS versions 1.0.0 through 1.9.0. This issue arises from uncontrolled resource consumption, allowing unauthenticated users to upload an unlimited number of files via the deprecated /api/v1/upload/{flow_id} endpoint. The lack of authentication and validation enables potential disk space exhaustion and information disclosure through absolute file path leakage in API responses.
Users are advised to upgrade IBM Langflow OSS to version 1.9.2. Instructions for upgrading can be found on the Langflow OSS page on the Python Package Index (PyPI).
