CVE-2026-6543
8.8IBM · Langflow Desktop
IBM Langflow Desktop 1.0.0 through 1.8.4 is susceptible to code injection, allowing an authenticated attacker to execute arbitrary commands with the privileges of the application process.
Executive summary
A critical code injection vulnerability in IBM Langflow Desktop allows an authenticated attacker to gain unauthorized command execution, potentially leading to full system compromise.
Vulnerability
This vulnerability is a code injection flaw (CWE-94) that permits an authenticated attacker to execute arbitrary commands. The attacker leverages the privileges of the process running Langflow to access sensitive environment variables, modify local files, or pivot into the internal network.
Business impact
The ability to execute arbitrary commands poses a severe risk to organizational security, as it can lead to the exfiltration of API keys, database credentials, and other sensitive configuration data. Given the CVSS score of 8.8, this vulnerability represents a high-severity threat that could result in significant data breaches, loss of intellectual property, or unauthorized lateral movement within the network.
Remediation
Immediate Action: Upgrade IBM Langflow Desktop to version 1.9.0 or newer immediately to apply the necessary security patches.
Proactive Monitoring: Review application access logs for unusual command execution patterns or unauthorized attempts to access environment variables.
Compensating Controls: Ensure the application is running with the principle of least privilege, minimizing the impact if the process is compromised.
Exploitation status
Public Exploit Available: No (exploit_available: false)
Analyst recommendation
The vulnerability presents a significant risk due to the potential for full command execution and credential theft. Administrators must prioritize upgrading to version 1.9.0 across all deployments immediately. Failure to patch allows persistent risk of unauthorized system access and data exposure.
