AI-suggested
A patch is available for FlowiseAI Flowise to remediate this vulnerability. Users should upgrade to version 3.1.4 or later. Since this is a cloud service, the vendor manages remediation for the hosted environment; users should verify with the vendor advisory for confirmation. No additional mitigation steps are indicated.
Description
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.
