CVE-2026-7761Network attack vector

Account takeover via password-reset link disclosure

Published Jun 24, 2026 · Updated Jun 24, 2026

Account takeover in Ultimate Member 2.11.4 and earlier allows remote authenticated users to seize accounts via disclosed reset links. The directory hash fallback accepts any post, post_data() matches um anywhere in a meta key, and build_user_card_data() outputs unvalidated password_reset_link fields. Contributor-level access and XML-RPC post creation are required; the crafted directory response exposes live reset URLs, including administrators' URLs.
