Authorization bypass via query parameter

Vibe & agenticSecuritySenior–Staff~19 min

An AI agent added an admin-only endpoint to delete any user. The product spec says only users with the `admin` role may call it. Auth middleware sets `req.user` from a verified JWT. The reviewer is checking whether the authorization is correct.

Implement
may_delete_user(authenticated: bool, actor_roles: list[str], required_role: str, request_flags: list[str]) → bool
Examples
in[true,["admin"],"admin",[]]outtrue
in[true,["member"],"admin",["force=true"]]outfalse
in[false,["admin"],"admin",[]]outfalse
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
