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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":2.3,"severity":"low","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},{"score":2.3,"severity":"low","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":4.3,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"}],"modifiedAt":1794331050770,"publishedAt":1794313580355,"references":[{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://wordpress.org/plugins/wck-custom-fields-and-custom-post-types-creator/#developers"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/wck-before-missing-authorization-via-wck-show-update-form-ajax"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://wordpress.org/plugins/wck-custom-fields-and-custom-post-types-creator/#developers"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/wck-before-missing-authorization-via-wck-show-update-form-ajax"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
