CVE-2026-86407 (GCVE-0-2026-86407)

Vulnerability from nvd – Published: 2026-09-13 06:00 – Updated: 2026-09-13 10:45

Title

User Registration & Membership < 5.2.8 - Unauthenticated User Data Disclosure via Membership Thank You Page

Summary

The User Registration & Membership WordPress plugin before 5.2.8 does not verify that the visitor requesting its membership confirmation page owns the account named in the request, nor that any registration or purchase has taken place, allowing unauthenticated users to retrieve another user's email address, profile fields, role and membership order details. Exploitation requires the site owner to have added a user smart tag to that page's configurable message, which the shipped default does not contain.

Severity

3.7 (Low)

CVE-2026-86406 (GCVE-0-2026-86406)

Vulnerability from nvd – Published: 2026-09-13 06:00 – Updated: 2026-09-13 10:45

Title

User Registration & Membership < 5.2.8 - Subscriber+ Privilege Escalation via Membership Purchase

Summary

The User Registration & Membership WordPress plugin before 5.2.8 does not check the capability of the user making a membership purchase, and does not validate the payment method or the plan submitted with it, allowing any authenticated user such as a subscriber to be granted the WordPress role attached to a paid plan without paying for it. Where the site owner has mapped a plan to a privileged role, this leads to privilege escalation up to administrator.

Severity

7.5 (High)

CVE-2026-86407 (GCVE-0-2026-86407)

Vulnerability from cvelistv5 – Published: 2026-09-13 06:00 – Updated: 2026-09-13 10:45

Title

User Registration & Membership < 5.2.8 - Unauthenticated User Data Disclosure via Membership Thank You Page

Summary

The User Registration & Membership WordPress plugin before 5.2.8 does not verify that the visitor requesting its membership confirmation page owns the account named in the request, nor that any registration or purchase has taken place, allowing unauthenticated users to retrieve another user's email address, profile fields, role and membership order details. Exploitation requires the site owner to have added a user smart tag to that page's configurable message, which the shipped default does not contain.

Severity

3.7 (Low)

CVE-2026-86406 (GCVE-0-2026-86406)

Vulnerability from cvelistv5 – Published: 2026-09-13 06:00 – Updated: 2026-09-13 10:45

Title

User Registration & Membership < 5.2.8 - Subscriber+ Privilege Escalation via Membership Purchase

Summary

The User Registration & Membership WordPress plugin before 5.2.8 does not check the capability of the user making a membership purchase, and does not validate the payment method or the plan submitted with it, allowing any authenticated user such as a subscriber to be granted the WordPress role attached to a paid plan without paying for it. Where the site owner has mapped a plan to a privileged role, this leads to privilege escalation up to administrator.

Severity

7.5 (High)
