CVE-2026-91936Network attack vector

Command execution via interpolated Docker workflow inputs

Published Sep 15, 2026 · Updated Sep 15, 2026

Script injection in Flowise before 3.1.4 allows remote authenticated users to execute commands through Docker build workflow inputs. Docker image workflows place tag_version and node_version values from workflow_dispatch directly into shell run blocks without safe parameter passing. Repository write access is required, and injected commands can read AWS credentials and Docker Hub tokens available to the workflow job.
