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."}],"title":"Welcome Software Publishing <= 0.0.31 - Authenticated (Subscriber+) Arbitrary Options Update to Privilege Escalation via 'nc.setOption' XML-RPC Method","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/47e53fd3-4e3f-433a-8e70-3a58c864184a?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L272"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L272"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L264"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L264"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L265"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L265"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/trunk/newscred.php#L44"},{"url":"https://plugins.trac.wordpress.org/browser/newscred-publishing/tags/0.0.31/newscred.php#L44"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Nabil Irawan"}],"timeline":[{"time":"2026-06-23T16:42:18.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-24T14:49:59.958116Z","id":"CVE-2026-4297","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-24T14:50:13.376Z"}}]}}
