CVE-2026-14499 is an OS command injection vulnerability (CWE-78) in IBM Langflow OSS versions 1.0.0 through 1.10.1. The flaw arises from improper neutralization of special elements in user-supplied input within the Python Interpreter component, enabling an authenticated attacker to execute arbitrary commands with elevated privileges on the host system. This vulnerability impacts confidentiality, integrity, and availability, as reflected by the CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). No vendor advisory or patch is currently available, and the product is not a cloud service, so remediation depends on vendor updates or mitigations.

Successful exploitation allows an authenticated user to execute arbitrary OS commands with elevated privileges, potentially leading to full system compromise including unauthorized data access, modification, or denial of service. The vulnerability affects confidentiality, integrity, and availability of the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently available, organizations should restrict access to the affected component to trusted users only and monitor for suspicious activity related to command execution. Follow vendor communications closely for updates on patches or mitigations.
