{"cve":"CVE-2026-103964","nvd":{"published":"2026-10-10T05:16:39.257","modified":"2026-10-13T13:30:21.620","status":"Deferred","description":"The Download Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.3.71 via the 'first_name' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the administrator's full Cookie header, including wordpress_logged_in_* session cookies, from the suspension email sent during the administrator's authenticated request, enabling full session hijack and account takeover. Exploitation requires an administrator to perform the Suspend action against the attacker's account, which causes the plugin to synchronously compile and send the suspension email inside the administrator's authenticated HTTP request — making the administrator's session cookies available to the template engine at send time.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200"],"references":["https://plugins.trac.wordpress.org/browser/download-manager/","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.71/src/User/UserController.php#L151","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.71/src/User/UserController.php#L180","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.71/src/__/Email.php#L382","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.71/src/__/Email.php#L383"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-103964","score":0.00243,"percentile":0.15344,"date":"2026-10-25"},"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).
