Langflow 1.0.x < 1.13.0 Multiple Vulnerabilities

critical Nessus Plugin ID 375489

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Langflow installed on the remote host is 1.0.x prior to 1.13.0. It is, therefore, affected by multiple vulnerabilities:

 - IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker to bypass security restrictions due to improper authentication. (CVE-2026-93680)

 - IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker to execute arbitrary code due to improper control of code generation. (CVE-2026-110186)

 - IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker with a low-privileged authenticated account to cause the Agentic Assistant to generate or submit component code using these unblocked patterns, resulting in arbitrary operating system command execution on the server. (CVE-2026-110193)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Langflow version 1.13.0 or later.
