Critical Flaws in Langflow AI Tool Allow Remote Server Takeover

Critical security vulnerabilities have been identified in Langflow, a popular open-source tool used to build artificial intelligence agents and workflows. Remote attackers can bypass authentication and run unauthorised code on host servers without needing any login credentials. Businesses using this software risk having their underlying systems compromised if deployments remain unpatched.
