CVE-2026-13442

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.
