## Overview

Cap-go capgo.app before 12.267.1 fails to validate target API key privilege during rotation, allowing an apikey_manager to rotate a higher-privileged org_super_admin sibling key and recover its plaintext credential. Attackers with apikey_manager role can enumerate same-owner API keys, rotate a stronger sibling through the PUT endpoint, and obtain the replacement plaintext secret to authenticate as the higher-privileged principal.
