Submit #853188: GitHub Dify 1.14.2 Injectioninfo

TitleGitHub Dify 1.14.2 Injection
DescriptionDify's Jinja2 code executor uses the unrestricted jinja2.Template() constructor instead of jinja2.SandboxedEnvironment(). This allows attackers to escape the template sandbox and achieve arbitrary code execution by abusing Python's object introspection capabilities (__class__, __mro__, __subclasses__, etc.). The same codebase correctly uses SandboxedEnvironment in other places (e.g. email rendering), indicating this is an inconsistency in security controls rather than a lack of awareness.
