This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. By default, Editor-level users are granted FULL_ACCESS to the plugin's import endpoint via the KIRKI_USERS_DEFAULT_FULL_ACCESS configuration, meaning exploitation is possible at Editor privilege level rather than being restricted to administrators alone.","state":0,"publishedAt":"2026-10-17T02:31:05.687+00:00","modifiedAt":"2026-10-18T11:22:47.982+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\": \"6.3.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3c760235-ee53-4906-9e25-19df85b8f8ff?source=cve","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.2/includes/ExportImport/TemplateImport.php#L987","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.2/includes/ExportImport/TemplateImport.php#L963","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.2/includes/Ajax/TemplateExportImport.php#L35","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.2/includes/Ajax.php#L802","https://plugins.trac.wordpress.org/changeset/3743904/kirki/trunk/includes/ExportImport/TemplateImport.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104734","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104734","identifiers":["CVE-2026-104734"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
