CVE-2026-35580 (GCVE-0-2026-35580)

Vulnerability from cvelistv5 – Published: 2026-04-07 15:55 – Updated: 2026-04-07 18:25

Title

Emissary has GitHub Actions Shell Injection via Workflow Inputs

Summary

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, GitHub Actions workflow files contained shell injection points where user-controlled workflow_dispatch inputs were interpolated directly into shell commands via ${{ }} expression syntax. An attacker with repository write access could inject arbitrary shell commands, leading to repository poisoning and supply chain compromise affecting all downstream users. This vulnerability is fixed in 8.39.0.

Severity

9.1 (Critical)
