CVE-2026-91936: Flowiseai Flowise

Medium severity, CVSS 6.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Flowiseai Flowise: before 3.1.4 (fixed in 3.1.4)
