[Langflow](https://langflow.org) is a powerful platform for building and deploying AI-powered agents and workflows. It provides developers with both a visual authoring experience and built-in API and MCP servers that turn every workflow into a tool that can be integrated into applications built on any framework or stack. Langflow comes with batteries included and supports all major LLMs, vector databases and a growing library of AI tools.

> [!CAUTION]

> - Users must update to Langflow >= 1.7.1 to protect against [CVE-2025-68477](https://github.com/langflow-ai/langflow/security/advisories/GHSA-5993-7p27-66g5) and [CVE-2025-68478](https://github.com/langflow-ai/langflow/security/advisories/GHSA-f43r-cc68-gpx4).

> - Langflow version 1.7.0 has a critical bug where persisted state (flows, projects, and global variables) cannot be found when upgrading. Version 1.7.0 was yanked and replaced with version 1.7.1, which includes a fix for this bug. DO NOT upgrade to version 1.7.0. Instead, upgrade directly to version 1.7.1.

> - Langflow versions 1.6.0 through 1.6.3 have a critical bug where .env files are not read, potentially causing security vulnerabilities. DO NOT upgrade to these versions if you use .env files for configuration. Instead, upgrade to 1.6.4, which includes a fix for this bug.

> - Windows users of Langflow Desktop should not use the in-app update feature to upgrade to Langflow version 1.6.0. For upgrade instructions, see [Windows Desktop update issue](https://docs.langflow.org/release-notes#windows-desktop-update-issue).

> - Users must update to Langflow >= 1.3 to protect against [CVE-2025-3248](https://nvd.nist.gov/vuln/detail/CVE-2025-3248)

> - Users must update to Langflow >= 1.5.1 to protect against [CVE-2025-57760](https://github.com/langflow-ai/langflow/security/advisories/GHSA-4gv9-mp8m-592r)
