{"apiVersion":"1.0","identifier":"CVE-2026-4244","description":"The Post Duplicator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `duplicate_post()` function in all versions up to, and including, 3.0.11. This is due to the function not verifying that the user has `edit_others_posts` capability before accepting a `selectedAuthorId` parameter via the `duplicate-post` REST endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicated posts attributed to any user, including administrators.","publishedAt":"2026-08-22T13:16:37","lastModifiedAt":"2026-08-24T16:41:13","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-4244","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00196,"riskScore":0.44,"affectedProduct":"Post Duplicator","affectedVersions":"<=3.0.11","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-4244","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-4244","en":"https://www.redsauce.net/en/cves/CVE-2026-4244","fr":"https://www.redsauce.net/fr/cves/CVE-2026-4244","pt":"https://www.redsauce.net/pt/cves/CVE-2026-4244","de":"https://www.redsauce.net/de/cves/CVE-2026-4244","sk":"https://www.redsauce.net/sk/cves/CVE-2026-4244","el":"https://www.redsauce.net/el/cves/CVE-2026-4244"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-4244"}}
