Attackers are actively exploiting a high-severity path traversal vulnerability in the Langflow AI development platform, security researchers warned. The flaw is tracked as CVE-2026-5027 and allows unauthorized access to files on affected servers.
Langflow is an open-source tool used by developers to build and deploy AI workflows. The path traversal bug enables remote attackers to read sensitive files outside the intended directory structure.
Researchers observed exploitation attempts in the wild shortly after the vulnerability was publicly disclosed. Organizations running Langflow instances were urged to apply patches immediately.
Path traversal flaws in AI infrastructure tools pose particular risks because the platforms often connect to proprietary data and model endpoints. Cybersecurity vendors have added detection signatures for known exploit patterns.
