This is due to the `maybe_add_role_to_user()` function unconditionally re-assigning every role stored in the `dfxwcrc_foreign_roles` user meta cache without verifying that each cached role is still actively assigned by the external provider — a condition made permanent by `remember_foreign_roles()`, which merges new foreign roles into the cache but never evicts roles that have since been revoked. This makes it possible for authenticated attackers with subscriber-level access and above to restore a previously revoked Administrator role to their own account, gaining full administrative control of the site, by triggering any role-assignment event such as completing a purchase for a role-mapped product. Exploitation requires Replace Roles mode to be enabled and the attacker's account to have previously received Administrator legitimately through a separate role-management mechanism while the plugin was active, so that `administrator` was written into the `dfxwcrc_foreign_roles` user meta cache before the external provider revoked it.","published":"2026-10-14T02:16:56.360","modified":"2026-10-14T02:16:56.360","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L351"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L414"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L427"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L468"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3732550%40dfx-woo-role-changer&new=3732550%40dfx-woo-role-changer"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/833d9f92-9af1-4332-9b1d-2d1d37073b4b?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-14T02:16:56.360"}}
