CVE-2024-9893Network attack vector

Account takeover via insufficient OAuth identity verification

Published Oct 16, 2024 · Updated Apr 8, 2026

Authentication bypass in Nextend Social Login Pro 3.1.14 and earlier allows remote attackers to take over accounts via WordPress.com OAuth. The WordPress.com provider insufficiently verifies the user returned by a social-login token before mapping that identity to an existing local account. Exploitation requires access to the victim's email address and no existing WordPress.com-linked account, and the resulting session inherits the victim's privileges.
