{"id":"CVE-2026-1499","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-1499","generatedAt":"2026-10-28T02:11:53.246Z","title":"The WP Duplicate plugin for WordPress is vulnerable to Missing Authorization leading to Arbitrary File Upload in all versions up to and including 1.1.8.","description":"The WP Duplicate plugin for WordPress is vulnerable to Missing Authorization leading to Arbitrary File Upload in all versions up to and including 1.1.8. This is due to a missing capability check on the `process_add_site()` AJAX action combined with path traversal in the file upload functionality. This makes it possible for authenticated (subscriber-level) attackers to set the internal `prod_key_random_id` option, which can then be used by an unauthenticated attacker to bypass authentication checks and write arbitrary files to the server via the `handle_upload_single_big_file()` function, ultimately leading to remote code execution.","published":"2026-02-06T09:15:49.000Z","lastModified":"2026-06-17T10:15:57.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","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"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.01059,"percentile":0.64291,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%).
