A fix is available — apply it.

Flowise versions before 3.1.4 contain a script injection vulnerability in Docker image build workflows where workflow_dispatch inputs are directly interpolated into shell run blocks. Attackers with repository write access can inject shell metacharacters through inputs like tag_version and node_version to execute arbitrary commands and steal AWS credentials and Docker Hub tokens.
