CVE-2026-12946: CWE-94 Improper Control of Generation of Code ('Code Injection') in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to inject arbitrary code on the system, due to the improper control of user input code.
AI Analysis
Technical Summary
CVE-2026-12946 is a critical vulnerability in IBM Langflow OSS (versions 1.0.0 through 1.10.0) involving improper control of code generation (CWE-94). This flaw allows a remote attacker with low privileges to inject arbitrary code on the affected system. The vulnerability impacts confidentiality, integrity, and availability with a CVSS 3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). No patch or official remediation level has been provided by IBM as of the publication date.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code remotely, leading to full compromise of the affected system's confidentiality, integrity, and availability. This could result in unauthorized data access, system manipulation, or denial of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected IBM Langflow OSS instances to trusted users only and monitor for suspicious activity related to code injection attempts.
