Langflow is affected by NET Misconfiguration: Use of Impersonation due to multiple unauthenticated and insufficiently authorized API endpoints
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an attacker to reuse another user's FAISS namespace to access owner-only vector content and influence later query results. This causes cross-user information disclosure and limited integrity impact through persistent poisoning of returned results.
