{"cve":"CVE-2026-1499","nvd":{"published":"2026-02-06T09:15:48.987","modified":"2026-06-17T10:15:56.960","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-admin.php#L422","https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-files-op.php#L843","https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/includes/class-local-sync-handle-server-requests.php#L389","https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-admin.php#L422","https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-files-op.php#L843"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-1499","score":0.01059,"percentile":0.64533,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
