This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to overwrite an administrator's password and gain administrative access.","state":0,"publishedAt":"2026-10-27T06:40:42.359+00:00","modifiedAt":"2026-10-29T01:52:00.797+00:00","affected":[{"ecosystem":"Vendor product","name":"Kirki – Freeform Page Builder, Website Builder & Customizer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"themeum\",\n                    \"product\": \"Kirki – Freeform Page Builder, Website Builder & Customizer\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"6.2.5\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/aecfea73-97fc-48c3-bf1b-5314077739b5?source=cve","https://plugins.trac.wordpress.org/changeset/3677965/kirki"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-75891","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-75891","identifiers":["CVE-2026-75891"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
