Between June 16-19, 2026, eight distinct security advisories were published on OSV for Langflow, ranging from path traversal (CVE-2026-42867, source) to unauthenticated RCE (CVE-2026-48519, source), IDOR vulnerabilities (CVE-2026-33760, CVE-2026-55255, sources, source), arbitrary file read (CVE-2026-48520, source), unauthenticated DoS (CVE-2026-55446, source), and session cleanup failure (CVE-2026-55423, source).
signal brief
Between June 16-19, 2026, eight distinct security advisories were published on OSV for Langflow, ranging from path traversal (CVE-2026-42867, source) to unauthenticated RCE (CVE-2026-48519, source), IDOR vulnerabilities (CVE-2026-33760, CVE-2026-55255, sources, source), arbitrary file read (CVE-2026-48520, source), unauthenticated DoS (CVE-2026-55446, source), and session cleanup failure (CVE-2026-55423, source). The rapid cluster of high-severity vulnerabilities signals potential security maturity gaps and may erode developer trust. Langflow's PyPI releases show daily dev updates (v1.11.0.dev7 through .dev13, June 14-20, source), suggesting active patching, but the breadth of issues indicates systemic weaknesses. For teams using Langflow in production or integrating with sensitive data, this represents a significant trust and safety risk. The collection's focus on AI infrastructure makes this relevant as a trust signal for the developer ecosystem.
