This is due to the `duplicate_post_permissions()` permission callback only verifying the `duplicate_posts` capability without checking whether the requesting user holds `publish_posts` or other status-gated capabilities. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicate posts with `future` (scheduled, auto-publishes) or `private` status, bypassing editorial review. Additionally, the REST endpoint does not enforce administrator-configured post-type duplication restrictions, allowing duplication of post types that have been explicitly disabled."}],"title":"Post Duplicator <= 3.0.11 - Authorization Bypass to Authenticated (Contributor+) Post Duplication","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bb671c8f-9e14-4f79-adfa-72f48ec02449?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L520"},{"url":"https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L635"},{"url":"https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L740"},{"url":"https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L624"},{"url":"https://plugins.trac.wordpress.org/changeset/3485579/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-863 Incorrect Authorization","cweId":"CWE-863","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Quốc Huy (jtwings)"}],"timeline":[{"time":"2026-03-15T22:02:45.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-21T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-24T20:01:25.244331Z","id":"CVE-2026-4245","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-24T20:01:34.600Z"}}]}}
