CVE-2026-86609: CWE-79 Cross-Site Scripting (XSS) in Download Manager
The Download Manager WordPress plugin before 7.5.6 does not sanitise and escape data submitted through its email-locked download subscription form before outputting it back in an admin page, which could allow unauthenticated attackers to perform Stored Cross-Site Scripting attacks against administrators. This affects the commercial Pro edition only; the free Download Manager WordPress plugin before 7.5.6 published under the same slug does not ship the affected feature.
AI Analysis
Technical Summary
The Download Manager WordPress plugin Pro edition versions from 4.0.0 up to but not including 7.5.6 contain a stored XSS vulnerability (CWE-79). This occurs because user input submitted via the email-locked download subscription form is output on an admin page without proper sanitization or escaping. An unauthenticated attacker can exploit this to execute arbitrary JavaScript in the administrator's browser context, potentially leading to session hijacking or other attacks targeting admin users. The free edition of the plugin does not include this feature and is not affected.
Potential Impact
Successful exploitation allows unauthenticated attackers to perform stored Cross-Site Scripting attacks against administrators, which can lead to administrative account compromise or unauthorized actions performed with administrator privileges. The impact is limited to administrators who view the affected admin page. The free edition of the plugin is not affected.
Mitigation Recommendations
Upgrade the Download Manager Pro plugin to version 7.5.6 or later, where this vulnerability is fixed. No other mitigations are indicated. Since this is a plugin vulnerability, patching is the recommended and effective remediation.
