CVE-2026-9033

Forced logout via unauthenticated session termination

Published Aug 20, 2026 · Updated Aug 20, 2026

Missing authentication in TP-Link Omada gateway captive portal service before listed fixed firmware allows remote attackers to terminate active sessions. TP-Link has not published the specific handler, but the captive portal service accepts session-termination requests without authenticating the caller, enabling logout of one user or clearing all active sessions. Reachability requires network access to the captive portal service, and the consequence is bounded to temporary captive-portal service interruption until affected users sign in again.
