signal brief
Between June 16-22, 2026, Langflow had 9 security advisories published on OSV (Open Source Vulnerabilities), covering a range of critical issues: GHSA-79ph-745m-6wxq (CVE-2026-42867, Path Traversal), GHSA-7hw8-6q6r-4276 (CVE-2026-55423, Session not cleared), GHSA-9c59-2mvc-vfr8 (CVE-2026-33760, IDOR/BOLA in Monitor API), GHSA-ccv6-r384-xp75 (CVE-2026-55447, Arbitrary file read + RCE), GHSA-qrpv-q767-xqq2 (CVE-2026-55255, IDOR in responses endpoint), GHSA-qwqc-p3q8-wcg9 (CVE-2026-55446, Unauthenticated DoS via multipart upload), GHSA-rcjh-r59h-gq37 (CVE-2026-48520, Unauthenticated file read in Shareable Playground), GHSA-v5ff-9q35-q26f (CVE-2026-48519, Unauthenticated RCE in Shareable Playgrounds), and GHSA-x223-p2gf-v735 (CVE-2026-55450, Unauthenticated file upload DoS/info leak). These vulnerabilities affect core APIs, shareable playbooks, and file handling. The rapid succession of dev releases (1.11.0.dev9 to .dev15 daily on PyPI) suggests active patching, but the volume of high-severity issues (RCE, unauthenticated access) poses significant trust and adoption risk for enterprise users. The Langflow website continues to market the platform as an enterprise-grade cloud, making these disclosures particularly damaging. The direction is down for Langflow, as security credibility is impacted.
