Attackers can send a crafted admin-ajax.php request with a valid wck-edit-entry nonce, a target meta key, and an arbitrary post ID to disclose sensitive post-meta or option values belonging to other users, including private or draft post data.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://wordpress.org/plugins/wck-custom-fields-and-custom-post-types-creator/#developers","tags":[]},{"url":"https://www.vulncheck.com/advisories/wck-before-missing-authorization-via-wck-show-update-form-ajax","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
