The possession of secrets is a recurrent theme in security literature and practice. We present a refinement type system, based on indexed intuitonist S4 necessity, for an object calculus with explicit locations (corresponding to principals) to control the principals that may possess a secret. Type safety ensures that if the execution of a well-typed program leads to a configuration with an object p located at principal a, then a possesses the capability to p. We illustrate the type system with
more &raquo; ... imple examples drawn from web applications, including an illustration of how Cross-Site Request Forgery (CSRF) vulnerabilities may manifest themselves as absurd refinements on object declarations during type checking. This is an extended version of a paper that appears in APLAS 2012.
