CVE-2026-86609

HighCVSS 8.8/10Last modified Sep 28, 2026

Description

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.
