What is CVE-2026-102401?
CVE-2026-102401 is a medium-severity cross-site scripting vulnerability in codename065 Download Manager, published on 10 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regurl' parameter in all versions up to, and including, 3.3.71 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload only fires for logged-out site visitors, as the vulnerable login-form.php template branch is gated on !is_user_logged_in(); authenticated users viewing the same page are served a different template and are not affected.
Weakness: CWE-79
