{“lastseen”:””,”description”:”The CMP \u2013 Coming Soon \\u0026 Maintenance Plugin by NiteoThemes plugin for WordPress is vulnerable to arbitrary file upload and remote code execution in all versions up to, and including, 4.1.16 via the `cmp_theme_update_install` AJAX action. 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.”,”published”:”2026-04-18T03:37:04.707Z”,”modified”:”2026-04-18T03:37:04.707Z”,”type”:”cve”,”title”:”CMP \u2013 Coming Soon \\u0026 Maintenance Plugin by NiteoThemes \\u003c= 4.1.16 – Missing Authorization to Authenticated (Administrator+) Arbitrary File Upload and Remote Code Execution”,”source”:”Wordfence”,”references”:”https:\/\/www.wordfence.com\/threat-intel\/vulnerabilities\/id\/d6fb275b-dbba-46df-b170-977ef4a84c4c?source=cve\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/cmp-coming-soon-maintenance\/tags\/4.1.16\/niteo-cmp.php#L1421\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/cmp-coming-soon-maintenance\/tags\/4.1.16\/niteo-cmp.php#L1437\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/cmp-coming-soon-maintenance\/tags\/4.1.16\/niteo-cmp.php#L1447\\nhttps:\/\/plugins.trac.wordpress.org\/changeset?old_path=%2Fcmp-coming-soon-maintenance\/tags\/4.1.16\\u0026new_path=%2Fcmp-coming-soon-maintenance\/tags\/4.1.17″,”id”:”CVE-2026-6518″,”bulletinFamily”:””,”cwe”:[“CWE-434″],”cvelist”:null,”sourceData”:”niteo CMP \u2013 Coming Soon \\u0026 Maintenance Plugin by NiteoThemes 0″,”sourceHref”:””,”cvss”:{“score”:8.8,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:L\/UI:N\/S:U\/C:H\/I:H\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”CMP \u2013 Coming Soon \\u0026 Maintenance Plugin by NiteoThemes”,”version”:”0″,”vendor”:”niteo”,”ai_description”:”Arbitrary file upload and remote code execution vulnerability in CMP \u2013 Coming Soon \\u0026 Maintenance Plugin by NiteoThemes up to version 4.1.16″,”ai_severity”:”High”,”ai_vendor”:”NiteoThemes”,”ai_product”:”CMP \u2013 Coming Soon \\u0026 Maintenance Plugin”,”ai_version”:”4.1.16″,”ai_score”:8.8}<\/p>\n","protected":false},"excerpt":{"rendered":"
