IBM Langflow OSS is vulnerable to remote code execution, which allows an authenticated attacker to gain full control over the affected system.

The application utilizes an unguarded eval() function on attacker-controlled input, leading to improper control of code generation (CWE-94). This vulnerability requires the attacker to have authenticated access to the system to trigger the malicious payload.

Successful exploitation of this vulnerability allows for remote code execution, which may lead to full system compromise, data exfiltration, or the deployment of persistent malware. Given the high CVSS score of 8.8, this flaw represents a significant risk to the confidentiality, integrity, and availability of the host environment.

Immediate Action: Administrators must upgrade IBM Langflow OSS to version 1.11.6 immediately as specified in the official vendor advisory.

Proactive Monitoring: Security teams should monitor system logs for suspicious process execution patterns or unusual user activity originating from authenticated sessions.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block suspicious input strings, particularly those containing code-like syntax, directed at the Langflow interface.

Public Exploit Available: No

Due to the severity of remote code execution, this vulnerability poses a critical threat to internal security. Organizations should prioritize the update to version 1.11.6 as the primary defense mechanism, ensuring that all authenticated users are audited for unauthorized activity until the patch is applied.
