CVE-2026-67427
CVE-2026-67427 · Flyto2 Core: ${env.VAR} interpolation reads any env secret despite env.get being denylisted
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.6, the workflow engine variable resolver expands ${env.VAR} for any host environment variable without an allowlist or capability policy check, allowing a workflow parameter to bypass the default capability policy denylist for env.get and env.load_dotenv and exfiltrate secrets through allowed modules. This issue is fixed in version 2.26.6.
