system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

"""
An administrator is a special kind of user. Write a class called
Admin that inherits from the User class you wrote in Exercise 9-3 (page 162)
or Exercise 9-5 (page 167). Add an attribute, privileges , that stores a list
of strings like "can add post" , "can delete post" , "can ban user" , and so on.
Write a method called show_privileges() that lists the administrator’s set of
privileges. Create an instance of Admin , and call your method.
