# CVE-2026-110523: WP User Manager 2.9.21 - 2.9.25 - Unauthenticated Privilege Escalation via Paid Registration Role After Stripe Disconnect

- Severity: CVSS 8.1 (High), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 2.9.26
- Published: 2026-10-21 · Updated: 2026-10-21

## Affected

- Unknown WP User Manager: from 2.9.21, fixed in 2.9.26

## Description

The WP User Manager WordPress plugin before 2.9.26 does not keep its paid-registration capability restrictions in force once the payment gateway is disconnected, while a published paid registration form continues to assign its configured role, allowing unauthenticated users to register and immediately obtain a privileged administrator-equivalent role without completing the payment meant to gate it.

## What to do

- Check your stack: if you ship or depend on Unknown WP User Manager, upgrade to a fixed version (2.9.26) per the references below.
