Description
Notification template Jinja AST whitelist only inspects static Getattr nodes. Dynamic subscripts (job['job'+'_env']) and {% if job.id > 100 %} conditional gating bypass both the AST check and the test-render (stub has small job.id). At runtime, the gated branch executes and exceptions write full tracebacks into notification body, which is POSTed to attacker-controlled webhook URL. Leaks install paths, Python version, source line numbers.

What to do
Workaround: Restrict notification template creation and editing privileges to trusted administrators only, since exploitation requires notification template admin privileges. Review existing notification templates for unexpected dynamic subscript expressions or conditional gating constructs, and limit outbound connectivity from automation controller nodes to approved webhook destinations so that notification content cannot be delivered to attacker-controlled endpoints.
