Stored Cross-Site Scripting in Simple Download Counter Plugin for WordPress

CVE-2023-4838

Summary

The Simple Download Counter plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping on user-supplied attributes, particularly 'before' and 'after'. This flaw allows authenticated attackers with contributor-level permissions or higher to inject malicious scripts through the plugin's shortcodes. As a result, affected websites may execute arbitrary web scripts when users access compromised pages, posing serious security risks. Users are encouraged to upgrade to a secure version of the plugin to mitigate this threat.
