Impact

IBM Langflow OSS versions 1.0.0 through 1.12.2 contain an OS command injection flaw caused by improper neutralization of special elements used in an operating‑system command. An attacker who can supply these elements can cause the application to execute arbitrary commands on the host machine, allowing full compromise of the affected system. The weakness is classified as CWE‑94, indicating unsanitized user input that is passed to an OS command executor.

Affected Systems

IBM Langflow OSS, specifically versions 1.0.0 up to and including 1.12.2, are impacted. Any installation of these releases that incorporates user input into OS command strings is vulnerable.

Risk and Exploitability

The vulnerability carries a CVSS score of 9.8, indicating critical severity. The EPSS score of 15% indicates a non-zero but moderately high exploitation probability, and the issue is not listed in CISA KEV catalog, but the high CVSS suggests it is a prime target for exploitation. An attacker can exploit the flaw remotely by sending specially crafted input that incorporates dangerous command constructs. The flaw allows arbitrary OS command execution on the host, providing full system compromise.

Remediation

Vendor Solution

IBM strongly recommends addressing the vulnerability now by upgrading Langflow OSS to version 1.12.3. https://pypi.org/project/langflow/#description

OpenCVE Recommended Actions

  • Upgrade IBM Langflow OSS to version 1.12.3 or later to eliminate the command injection flaw.
  • If an upgrade is not immediately feasible, review the code that builds OS commands and enforce stricter sanitization or remove the use of special elements altogether before passing data to the OS.
  • Continuously monitor system logs for signs of unexpected command execution or suspicious input patterns to detect attempted or successful exploitation.
