CVE-2026-7803: CWE-20 Improper Input Validation in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.10.0 could allow arbitrary code execution due to improper validation of flow nodes with missing or empty component type fields.
AI Analysis
Technical Summary
CVE-2026-7803 is a critical vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.0 caused by improper input validation (CWE-20) of flow nodes that have missing or empty component type fields. This validation flaw can be exploited remotely by an unauthenticated attacker to achieve arbitrary code execution, impacting confidentiality, integrity, and availability of the affected system. No official patch or remediation guidance has been published by IBM as of the data provided.
Potential Impact
Successful exploitation of this vulnerability allows remote attackers to execute arbitrary code on affected IBM Langflow OSS installations, leading to full compromise of the system. The CVSS score of 9.8 reflects high impact on confidentiality, integrity, and availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected IBM Langflow OSS instances and monitor for suspicious activity related to flow node inputs. Avoid processing untrusted flow node data.
