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by `remember_foreign_roles()`, which merges new foreign roles into the cache but never evicts roles that have since been revoked.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."}],"title":"Membership & User Roles for WooCommerce (Automatic Role Changer) <= 20260828 - Authenticated (Subscriber+) Privilege Escalation to Stale Foreign Role Cache","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/833d9f92-9af1-4332-9b1d-2d1d37073b4b?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L468"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L427"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L414"},{"url":"https://plugins.trac.wordpress.org/browser/dfx-woo-role-changer/trunk/dfx-woo-role-changer.php#L351"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3732550%40dfx-woo-role-changer&new=3732550%40dfx-woo-role-changer"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"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"}}],"credits":[{"lang":"en","type":"finder","value":"Azgnt"}],"timeline":[{"time":"2026-10-07T11:22:33.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-13T12:40:58.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-104767","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-15T10:52:56.368683Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-15T16:43:51.168Z"}}]}}
