CVE-2026-13444

Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints

Published Jul 30, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an attacker to access another user's private vector documents by creating their own flow with matching Chroma persist_directory and collection_name values. The attacker receives exact victim content in their workflow output despite having no authorization to read the victim's flow. Additionally, the attacker can pollute the victim's collection by inserting their own documents into the shared namespace.

Remediation

Vendor Solution
