Detailsinfo

A vulnerability was found in codename065 Download Manager Plugin up to 3.3.71. It has been declared as problematic. This vulnerability affects an unknown code block. The manipulation of the argument first_name with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability was named CVE-2026-103964 since 10/01/2026. The exploitation appears to be easy. The attack can be initiated remotely.
