This is due to the function only checking for the `publish_pages` capability (available to Editors and above) instead of `manage_options` (Administrators only), combined with a lack of proper validation on the user-supplied file URL and no verification of the downloaded file's content before extraction. This makes it possible for authenticated attackers, with Administrator-level access and above, to force the server to download and extract a malicious ZIP file from a remote attacker-controlled URL into a web-accessible directory (`wp-content/plugins/cmp-premium-themes/`), resulting in remote code execution. Due to the lack of a nonce for Editors, they are unable to exploit this vulnerability."}],"title":"CMP – Coming Soon & Maintenance Plugin by NiteoThemes <= 4.1.16 - Missing Authorization to Authenticated (Administrator+) Arbitrary File Upload and Remote Code Execution","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/d6fb275b-dbba-46df-b170-977ef4a84c4c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/cmp-coming-soon-maintenance/tags/4.1.16/niteo-cmp.php#L1421"},{"url":"https://plugins.trac.wordpress.org/browser/cmp-coming-soon-maintenance/tags/4.1.16/niteo-cmp.php#L1437"},{"url":"https://plugins.trac.wordpress.org/browser/cmp-coming-soon-maintenance/tags/4.1.16/niteo-cmp.php#L1447"},{"url":"https://plugins.trac.wordpress.org/changeset?old_path=%2Fcmp-coming-soon-maintenance/tags/4.1.16&new_path=%2Fcmp-coming-soon-maintenance/tags/4.1.17"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","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":"ll"}],"timeline":[{"time":"2026-04-17T15:02:18.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-6518","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-04-20T13:39:46.692921Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-20T13:46:08.222Z"}}]}}
