CVE-2026-110196 · Severity: high · CVSS 8.8 · Published 2026-10-29

IBM Langflow OSS is a low-code platform for building AI applications, allowing non-technical users to create workflows with code components. A low-privileged authenticated user can bypass administrator-only restrictions and execute arbitrary code on the server by misconfiguring built-in code-execution components, leading to complete server compromise. This affects versions 1.0.0 through 1.12.4 and requires valid user authentication to exploit.

## Technical details

This is a missing authorization vulnerability (CWE-862) in the code-execution component of Langflow OSS. An authenticated attacker with low privileges can configure a built-in component with attacker-supplied inputs to bypass administrator-only restrictions and achieve arbitrary code execution under the server process. The vulnerability requires network access and valid authentication credentials but no user interaction.
