{"schema":"threatline.record/2","record":{"id":"CVE-2026-93901","aliases":[],"summary":"Optima Express IDX <= 8.7.5 - Unauthenticated Privilege Escalation to 'ihf_clear_cache' AJAX Action to Author Role Assignment","details":"The Optima Express IDX plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 8.7.5. 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.","categories":["Frameworks"],"product":"Optima Express IDX","vendor":"ihomefinder","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93901","source_modified_at":"2026-09-25T13:00:14.639Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Optima Express IDX","vendor":"ihomefinder","versions":[{"version":"0","status":"affected","lessThanOrEqual":"8.7.5","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00346,"percentile":0.26927,"score_date":"2026-10-23"},"published_at":"2026-09-25T07:40:28.520Z","modified_at":"2026-09-25T13:00:14.639Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93901","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T13:00:14.639Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93901","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/8ba63df6-ae71-4320-bb82-87d6e17cc47d?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L818"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L795"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAjaxHandler.php#L146"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinder.php#L291"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L369"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L498"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinder.php#L176"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/optima-express/tags/8.7.5/iHomefinderAdmin.php#L752"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3706448%40optima-express&new=3706448%40optima-express"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-25T12:50:36.846826Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-25T13:00:14.639Z","content_hash":"2c10e1745d042b879f12c7c98fb1cecc5fa92431d63d7fdfe26403fc05f071f0"}}
