{"schema":"threatline.record/2","record":{"id":"CVE-2026-94589","aliases":[],"summary":"Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) <= 3.4.5 - Unauthenticated Arbitrary File Upload via Signature Field File Upload","details":"The Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.4.5 via the extcf7_submit function. This is due to missing file extension, MIME type, and size validation in the signature field's validation_filter(), combined with the absence of PHP-execution guards in the upload directory and a sanitize_file_name() bypass that converts shell.php- into shell.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.","categories":["Unclassified"],"product":"Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection)","vendor":"htplugins","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94589","source_modified_at":"2026-10-11T16:55:19.810Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection)","vendor":"htplugins","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.4.5","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00656,"percentile":0.50808,"score_date":"2026-10-23"},"published_at":"2026-10-10T03:26:46.082Z","modified_at":"2026-10-11T16:55:19.810Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94589","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T16:55:19.810Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94589","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/fa3193c4-dd3e-4d9e-be42-769c7358beae?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/includes/class.form-data-store.php#L42"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/admin/include/class.cf7-signature.php#L222"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/admin/include/class.cf7-signature.php#L82"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/extensions-for-cf7/tags/3.4.5/includes/class.cf7-extensions.php#L289"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3727009%40extensions-for-cf7%2Ftags%2F3.4.6&old=3672142%40extensions-for-cf7%2Ftags%2F3.4.5"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3727009/extensions-for-cf7/trunk/admin/include/class.cf7-signature.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-11T16:43:32.558627Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-11T16:55:19.810Z","content_hash":"b2c35d651f474070a802cb2492cbc15db2bdaef73bd3fb15f2eb419014221a44"}}
