CVE-2026-86814 Details
Description
The UsersWP WordPress plugin before 1.5.10 does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account, allowing unauthenticated attackers to log in as any user, including administrators, whose email address they can assert through a provider account of their own.
A vulnerability in the UsersWP WordPress plugin, affecting versions prior to 1.5.10, allows unauthenticated attackers to log in as any user, including administrators. The issue arises because the plugin does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account. This lack of verification enables attackers to assert ownership of an email address through their own provider account and gain unauthorized access.
Users are advised to update the UsersWP WordPress plugin to version 1.5.10 or later.
