When no WildApricot contact-ID mapping is found for an incoming SSO login, the plugin falls back to a network-global `get_user_by('email', ...)` lookup in `Module.php` to resolve a WordPress user, then `UserSynchronizer::syncWaContact()` binds and `Controller::login()` issues a session cookie via `wp_set_auth_cookie()` for that resolved user — both guarded only by `is_super_admin()` — without ever requiring proof of ownership of the matched WordPress account such as a password, local account-linking confirmation, inbox verification, or administrator approval. This makes it possible for attackers with custom-level WildApricot membership access to authenticate as an existing WordPress subsite administrator on a path-based Multisite network, obtaining a valid network-global authentication cookie for the victim without their credentials. Exploitation requires that the attacker control a WildApricot contact whose email address matches the target WordPress administrator's email — achievable via a public zero-fee membership application on the connected WildApricot organization — and that they complete the SSO flow on any subsite where Wild Apricot Login is active; because WordPress user identities and authentication cookies are network-global, the cookie issued on that subsite is equally valid on any other subsite where the victim user holds an administrator role.","state":0,"publishedAt":"2026-10-29T03:39:15.801+00:00","modifiedAt":"2026-10-29T10:45:42.405+00:00","affected":[{"ecosystem":"Vendor product","name":"Wild Apricot Login","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wild-apricot\",\n                    \"product\": \"Wild Apricot Login\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.0.18\",\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/9adbe55e-f1a1-4fa8-b28d-539d90d81c68?source=cve","https://plugins.trac.wordpress.org/browser/wild-apricot-login/tags/1.0.18/Modules/Authorization/WaLogin/Controller.php#L347","https://plugins.trac.wordpress.org/browser/wild-apricot-login/tags/1.0.18/Modules/Core/WaApi/Client.php#L22","https://plugins.trac.wordpress.org/browser/wild-apricot-login/tags/1.0.18/Modules/Core/Module.php#L159","https://plugins.trac.wordpress.org/browser/wild-apricot-login/tags/1.0.18/Modules/Synchronization/UserSynchronizer.php#L36","https://plugins.trac.wordpress.org/browser/wild-apricot-login/tags/1.0.18/Modules/Core/Module.php#L112"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93757","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93757","identifiers":["CVE-2026-93757"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
