CVE-2026-81940: CWE-94 Improper Control of Generation of Code ('Code Injection') in IBM Langflow OSS
IBM Langflow OSS versions 1.0.0 through 1.11.5 contain a vulnerability that allows remote authenticated attackers to execute arbitrary code. This occurs due to improper neutralization of special characters in flow display names, leading to code injection. The vulnerability has a high severity with a CVSS score of 8.8.
AI Analysis
Technical Summary
CVE-2026-81940 is a code injection vulnerability (CWE-94) in IBM Langflow OSS versions 1.0.0 through 1.11.5. It arises from improper control of the generation of code caused by insufficient neutralization of special characters in flow display names. This flaw enables a remote attacker with authentication privileges to execute arbitrary code on the affected system.
Potential Impact
Successful exploitation allows a remote authenticated attacker to execute arbitrary code, potentially leading to full system compromise. The vulnerability impacts confidentiality, integrity, and availability, as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to trusted users only and monitor for suspicious activity related to flow display names.
