Summary

IBM Langflow OSS versions 1.0.0 through 1.12.2 contain a code injection flaw (CWE-94) caused by improper input validation. A remote authenticated attacker can exploit it to execute arbitrary code through special OS command elements. The CVSS 3.1 base score is 8.8 (HIGH). CISA has not added the issue to KEV, and its SSVC assessment lists exploitation as none, not automatable, with total technical impact.

Remediation

No fixed version is listed for Langflow OSS. Until IBM publishes one, limit which users can authenticate to Langflow instances, because the attack requires an authenticated user.
