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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-434"],"references":["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/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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-82901","score":0.04328,"percentile":0.91187,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
