RISK

Why arvan_create_security_rule is rated Medium

While security rule misconfiguration could have severe consequences (enabling unwanted access), the action itself is reversible (rules can be deleted/modified). Classified as Write rather than Execute because it configures infrastructure rather than executing arbitrary code.
