Last modified

CVE-2026-91936 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. 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.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
