CVE-2026-104767 · Severity: high · CVSS 7.5 · Published 2026-10-14

The Membership & User Roles for WooCommerce plugin for WordPress fails to verify that cached user roles are still valid, allowing authenticated users to restore previously revoked administrator access. An attacker with subscriber-level or higher access can regain full administrative control of a WordPress site by triggering a role-assignment event, such as completing a product purchase, if they previously held an administrator role that was then revoked.

## Technical details

The plugin's `maybe_add_role_to_user()` function re-assigns cached roles from the `dfxwcrc_foreign_roles` user meta without validating that the external provider still grants those roles. The `remember_foreign_roles()` function merges new roles into the cache but never removes revoked ones, allowing revoked administrator roles to persist. When triggered (e.g., on product purchase in Replace Roles mode), the cached administrator role is restored, granting full site access to an authenticated attacker whose role was previously revoked by an external provider.
