WordPress · The Registration Forms – User Profile · CVE-2021-24647
**Name of the Vulnerable Software and Affected Versions**
The Registration Forms – User profile, Content Restriction, Spam Protection, Payment Gateways, Invitation Codes WordPress plugin versions prior to 3.1.7.6
**Description**
The issue is related to a flaw in the social login implementation, allowing an unauthenticated attacker to login as any user on the site by only knowing their `user id` or `username`.
**Recommendations**
For versions prior to 3.1.7.6, update to version 3.1.7.6 or later to resolve the issue. As a temporary workaround, consider restricting access to social login features until the update is applied. Avoid using the `username` or `user id` parameters in sensitive operations until the issue is resolved.
