CVE-2026-10561: CWE-94 Improper Control of Generation of Code ('Code Injection') in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.9.3 has an vulnerability due to an improper isolation of Python execution combined with an authentication bypass that allows an unauthenticated attacker to execute arbitrary code on the host system, resulting in complete compromise
AI Analysis
Technical Summary
CVE-2026-10561 is a critical code injection vulnerability in IBM Langflow OSS versions 1.0.0 through 1.9.3. The issue arises from improper isolation of Python code execution combined with an authentication bypass, enabling unauthenticated attackers to execute arbitrary code on the host system. This results in complete compromise of the affected system. The vulnerability has a CVSS 3.1 score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). No official remediation or patch has been published by IBM as of the data provided.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary code remotely on the host system running IBM Langflow OSS, resulting in full system compromise with complete confidentiality, integrity, and availability impact.
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 IBM Langflow OSS instances and monitor for suspicious activity. Avoid exposing the service to untrusted networks.
