CVE-2026-85378Public exploitNetwork attack vector

Unauthenticated content modification via skipped authorization initializer

Published Sep 3, 2026 · Updated Sep 3, 2026

Authorization bypass in light0011 cms allows remote attackers to alter administrative content without a session over the network. ChapterController extends Think\Controller instead of AuthController, so AuthController::_initialize never applies session and role checks. Exposed chapter endpoints permit content listing and writes, enabling article alteration or removal without an authenticated account.
