CVE-2026-78362Network attack vector

Unauthenticated site takeover via faulty API authentication

Published Sep 5, 2026 · Updated Sep 6, 2026

Privilege escalation in SEO Flow by LupsOnline before 3.0.3 allows remote attackers to take over configured WordPress sites. The API request authentication path incorrectly validates the supplied credential and resolves the request as the administrator who configured the plugin. The site must already be configured with its normal API code, after which the attacker receives that administrator's authority over the site.
