This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: This is only exploitable when the plugin's PDF Generator module is enabled, which is disabled by default.","state":0,"publishedAt":"2026-09-26T18:28:25.922+00:00","modifiedAt":"2026-09-26T22:51:16.926+00:00","affected":[{"ecosystem":"Vendor product","name":"Ultra Addons for Contact Form 7","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"themefic\",\n                    \"product\": \"Ultra Addons for Contact Form 7\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.5.50\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/872e1a05-aacc-44fa-93c1-8c3f7b2fb46d?source=cve","https://plugins.trac.wordpress.org/browser/ultimate-addons-for-contact-form-7/tags/3.5.48/addons/signature/ultimate-signature.php#L133","https://plugins.trac.wordpress.org/browser/ultimate-addons-for-contact-form-7/tags/3.5.48/addons/signature/ultimate-signature.php#L192","https://plugins.trac.wordpress.org/browser/ultimate-addons-for-contact-form-7/tags/3.5.48/addons/signature/ultimate-signature.php#L300","https://plugins.trac.wordpress.org/browser/ultimate-addons-for-contact-form-7/tags/3.5.48/addons/pdf-generator/pdf-generator.php#L608","https://plugins.trac.wordpress.org/browser/ultimate-addons-for-contact-form-7/tags/3.5.48/addons/pdf-generator/pdf-generator.php#L807","https://plugins.trac.wordpress.org/changeset/3698232/ultimate-addons-for-contact-form-7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82901","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82901","identifiers":["CVE-2026-82901"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
