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by `remember_foreign_roles()`, which merges new foreign roles into the cache but never evicts roles that have since been revoked.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."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"davefx","product":"Membership & User Roles for WooCommerce (Automatic Role Changer)","defaultStatus":"unaffected","versions":[{"version":"0","lessThanOrEqual":"20260828","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.6,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-15T10:52:56.368683Z","id":"CVE-2026-104767","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@wordfence.com","type":"Secondary","description":[{"lang":"en","value":"CWE-269"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L351","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L414","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L427","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L468","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3732550%40dfx-woo-role-changer&new=3732550%40dfx-woo-role-changer","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/833d9f92-9af1-4332-9b1d-2d1d37073b4b?source=cve","source":"security@wordfence.com"}]}}]}
