This is due to the `provisionBlogCredentials()` function in `iHomefinderAdmin.php` being reachable via the `wp_ajax_nopriv_ihf_clear_cache` AJAX action — through the call chain `iHomefinderAjaxHandler::clearCache()` → `activateAuthenticationToken()` → `getAuthenticationInfo()` → `provisionBlogCredentials()` — with no capability check, nonce verification, or ownership validation, and the function unconditionally calling `$user->set_role('author')` on whichever WordPress account matches the hard-coded login `optima-express` via `get_user_by('login', 'optima-express')`. This makes it possible for unauthenticated attackers to escalate a pre-registered `optima-express` account to the Author role, gaining `publish_posts`, `upload_files`, and `edit_published_posts` capabilities, including access to the plugin's own `/wp-json/optima-express/v1/blog-post` REST endpoint. Exploitation requires open user registration to be enabled on the target site, and the attacker must register the `optima-express` username before the plugin has had the opportunity to provision that login for its own integration account.","state":0,"publishedAt":"2026-09-25T07:40:28.52+00:00","modifiedAt":"2026-09-25T13:00:14.639+00:00","affected":[{"ecosystem":"Vendor product","name":"Optima Express IDX","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ihomefinder\",\n                    \"product\": \"Optima Express IDX\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"8.7.5\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8ba63df6-ae71-4320-bb82-87d6e17cc47d?source=cve","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L818","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L795","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAjaxHandler.php#L146","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinder.php#L291","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L369","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L498","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinder.php#L176","https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L752","https://plugins.trac.wordpress.org/changeset?reponame=&old=3706448%40optima-express&new=3706448%40optima-express"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93901","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93901","identifiers":["CVE-2026-93901"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
