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 flaw arises from improper isolation of Python code execution alongside an authentication bypass, enabling unauthenticated attackers to execute arbitrary code on the host system. This leads to full compromise of confidentiality, integrity, and availability of the affected system. The vulnerability has a CVSS 3.1 base score of 10.0, reflecting its critical severity and ease of exploitation over the network without privileges or user interaction.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary code on the host system, resulting in complete compromise of the affected system's confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time. Users should monitor IBM's advisories for updates and apply patches once available.
