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.
