This is due to the Ajax_Service::verify_ajax_request() helper gating its wp_verify_nonce() call behind the boolean option 'enable_nonce_check', which is absent from the default 'wpo365_options' array and therefore evaluates to false via get_global_boolean_var(); as a result, the wp_ajax_wpo365_update_settings handler (Ajax_Service::update_settings) accepts POSTs from cross-origin pages and forwards the attacker-supplied 'settings' payload (base64/JSON) to Options_Service::update_options(), which merges every key/value into wpo365_options without a key allowlist. This makes it possible for unauthenticated attackers to overwrite arbitrary plugin options — including enabling the SCIM REST endpoint (enable_scim), planting an attacker-known scim_secret_token, and setting new_usr_default_role to 'administrator' — via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.","publishedAt":"2026-07-23T19:45:52.225Z","updatedAt":"2026-07-24T14:27:08.898Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["wpo365 WPO365 | SEAMLESS WORDPRESS + MICROSOFT INTEGRATION (WPO365 | LOGIN)"],"affected":[{"vendor":"wpo365","product":"WPO365 | SEAMLESS WORDPRESS + MICROSOFT INTEGRATION (WPO365 | LOGIN)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"43.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/51d0ba58-614e-4284-ae0b-b0b76fc5c46d?source=cve","https://plugins.trac.wordpress.org/browser/wpo365-login/tags/43.2/Services/Ajax_Service.php#L805","https://plugins.trac.wordpress.org/changeset/3610759/wpo365-login"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15212.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15212","state":"PUBLISHED","datePublished":"2026-07-23T19:45:52.225Z","dateUpdated":"2026-07-24T14:27:08.898Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-09T07:43:41.039Z"},"containers":{"cna":{"title":"WPO365 | SEAMLESS WORDPRESS + MICROSOFT INTEGRATION (WPO365 | LOGIN) <= 43.2 - Cross-Site Request Forgery to Privilege Escalation via Plugin Settings Update","descriptions":[{"lang":"en","value":"The WPO365 | Login plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 43.2.
