CVE-2026-86609: Unknown Download Manager

High severity, CVSS 8.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Download Manager: from 4.0.0, before 7.5.6 (fixed in 7.5.6)
