The Download Attachments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'download-attachments' shortcode in all versions up to, and including, 1.3 due to insufficient input sanitization and output escaping on user supplied attributes. 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 Download Attachments WordPress plugin before 1.3 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

Directory traversal vulnerability in the Download Zip Attachments plugin 1.0 for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the File parameter to download.php.
