CVE-2026-93680 is an incomplete fix of an earlier auto-login issue, CVE-2026-110186 allows unauthenticated code execution through MCP tool enumeration, and CVE-2026-110193 needs at least a low-privileged account. The flaws affect versions 1.0.0 to 1.12.8 and are fixed in 1.13.0.","solution":"Fixed in Langflow 1.13.0, available from PyPI and as a Docker image.
