CVE-2026-13733
MediumCVSS 6.4Exploitation Probability (EPSS)
Low risk11th percentile — higher than 11% of all known CVEs
Summary
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'no_data_msg' shortcode attribute in all versions up to and including 3.3.60 due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts that execute when a user visits an injected page.
Risk Assessment
Attackers can inject malicious JavaScript that executes on every visit to an infected page, potentially leading to session theft, redirects, or other harmful actions.
Recommendation
Immediately update the Download Manager plugin to the latest available version that fixes this vulnerability, and review existing content for potentially malicious shortcode attributes.
Original NVD description (English source)
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute in all versions up to, and including, 3.3.60 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. Although wp_kses_post is applied to post content on save, it only strips HTML tokens and does not neutralize C-style escape sequences embedded within shortcode attribute values, meaning contributors can craft a payload that survives the kses filter and is silently reconstructed into a raw script tag at render time.
