Description
Firekylin through 2.18.1 contains an improper authorization vulnerability that allows editor-role users to read administrator-only secrets because the admin API base guard permits all GET actions. Editors can query options.js for TOTP secrets, push credentials, and cloud storage keys, or user.js for other users' app_key/app_secret to publish posts as administrators via admin/post_push.
