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.","categories":["Unclassified"],"product":"Kirki – Freeform Page Builder, Website Builder & Customizer","vendor":"themeum","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-75891","source_modified_at":"2026-10-27T06:40:42.359Z","fetched_at":"2026-10-27T10:24:27.527526Z","product":"Kirki – Freeform Page Builder, Website Builder & Customizer","vendor":"themeum","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.2.5","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T06:40:42.359Z","modified_at":"2026-10-27T06:40:42.359Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-75891","fetched_at":"2026-10-27T10:24:27.527526Z","source_modified_at":"2026-10-27T06:40:42.359Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/aecfea73-97fc-48c3-bf1b-5314077739b5?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3677965/kirki"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T06:40:42.359Z","content_hash":"9e94c853b0f999cb77d34ced03baab8c0c036aa3becebe2d9ab3dcc0cf48cddd"}}
