CVE-2026-18632Public exploitNetwork attack vector

Authenticated command execution via unsandboxed Jinja templates

Published Aug 3, 2026 · Updated Aug 3, 2026

Server-side template injection in LangGenius Dify 1.14.0 through 1.14.2 allows remote authenticated users to execute sandboxed commands. Jinja2TemplateTransformer passes attacker-controlled template code to jinja2.Template and renders it without SandboxedEnvironment restrictions. Workspace access to create or run a workflow is required, and resulting commands execute inside Dify's code-execution sandbox.
