CVE-2026-18052Network attack vector

Administrator session hijacking via replayable login links

Published Aug 22, 2026 · Updated Aug 22, 2026

Authentication bypass in GoDaddy ManageWP Worker before 4.9.37 allows remote attackers to obtain any site user's session via a captured login link. The automatic login handler validates a signature that is not bound to the target account and accepts previously used link tokens, enabling account substitution and replay. Possession of a valid auto-login link is required; replay can create an administrator session with full site control.
