{"id":"CVE-2026-4297","state":"PUBLISHED","title":"Welcome Software Publishing <= 0.0.31 - Authenticated (Subscriber+) Arbitrary Options Update to Privilege Escalation via 'nc.setOption' XML-RPC Method","description":"The Welcome Software Publishing plugin for WordPress is vulnerable to Arbitrary Options Update in all versions up to and including 0.0.31. This is due to a missing capability check in the nc_setOption() function, which is exposed via the nc.setOption XML-RPC method. The function authenticates the user via $wp_xmlrpc_server->login() (verifying credentials are valid) but does not perform any authorization check such as current_user_can('manage_options'). This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary WordPress options via XML-RPC requests. This can be leveraged to change the default_role option to 'administrator' and then register a new administrator account, achieving full privilege escalation and site takeover.","publishedAt":"2026-06-24T05:33:24.530Z","updatedAt":"2026-06-24T14:50:13.376Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["newscred Welcome Software Publishing"],"affected":[{"vendor":"newscred","product":"Welcome Software Publishing","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.0.31","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/47e53fd3-4e3f-433a-8e70-3a58c864184a?source=cve","https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L272","https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L272","https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L264","https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L264","https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L265","https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L265","https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L44","https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L44"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4297.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4297","state":"PUBLISHED","datePublished":"2026-06-24T05:33:24.530Z","dateUpdated":"2026-06-24T14:50:13.376Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-16T18:58:52.144Z"},"containers":{"cna":{"title":"Welcome Software Publishing <= 0.0.31 - Authenticated (Subscriber+) Arbitrary Options Update to Privilege Escalation via 'nc.setOption' XML-RPC Method","descriptions":[{"lang":"en","value":"The Welcome Software Publishing plugin for WordPress is vulnerable to Arbitrary Options Update in all versions up to and including 0.0.31.
