In versions up to and including 29.0, objects/users.json.php exposes two unauthenticated paths that disclose the full set of registered user accounts. The isCompany request parameter causes the handler to set $ignoreAdmin = true for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside User::getAllUsers()/User::getTotalUsers(). A second path accepts users_id and calls User::getUserFromID() directly with no permission check, producing a single-user oracle. Both paths return id, identification (display name), channel URL, photo, background, and status, plus the total account count. Commit d9cdc702481a626b15f814f6093f1e2a9c20d375 contains an updated fix."}], "lastModified": "2026-05-12T14:50:18.527", "sourceIdentifier": "security-advisories@github.com"}
