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by `remember_foreign_roles()`, which merges new foreign roles into the cache but never evicts roles that have since been revoked.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.","state":0,"publishedAt":"2026-10-14T01:27:14.736+00:00","modifiedAt":"2026-10-15T16:43:51.168+00:00","affected":[{"ecosystem":"Vendor product","name":"Membership & User Roles for WooCommerce (Automatic Role Changer)","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"davefx\",\n                    \"product\": \"Membership & User Roles for WooCommerce (Automatic Role Changer)\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"20260828\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/833d9f92-9af1-4332-9b1d-2d1d37073b4b?source=cve","https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L468","https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L427","https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L414","https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L351","https://plugins.trac.wordpress.org/changeset?reponame=&old=3732550%40dfx-woo-role-changer&new=3732550%40dfx-woo-role-changer"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104767","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104767","identifiers":["CVE-2026-104767"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
