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."}],"title":"WP Duplicate <= 1.1.8 - Authenticated (Subscriber+) Arbitrary File Upload via 'process_add_site' AJAX Action","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/11bb7190-023b-45e1-99a5-7313c489ef45?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-admin.php#L422"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-admin.php#L422"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/trunk/includes/class-local-sync-handle-server-requests.php#L389"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/includes/class-local-sync-handle-server-requests.php#L389"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/trunk/admin/class-local-sync-files-op.php#L843"},{"url":"https://plugins.trac.wordpress.org/browser/local-sync/tags/1.1.8/admin/class-local-sync-files-op.php#L843"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3452904%40local-sync&old=3400317%40local-sync&sfp_email=&sfph_mail="}],"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":"Athiwat Tiprasaharn"}],"timeline":[{"time":"2026-01-30T11:21:13.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-02-05T19:59:16.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-14T15:12:17.995769Z","id":"CVE-2026-1499","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":"2026-04-14T15:12:22.866Z"}}]}}
