Vulnerability in Plugin-Planet Simple Download Counter
CVE-2023-4838
The Simple Download Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 1.6 due to insufficient input sanitization and output escaping on user supplied attributes like 'before' and 'after'. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
