CVE-2023-4838

Name of the Vulnerable Software and Affected Versions The Simple Download Counter plugin for WordPress versions up to, and including, 1.6

Description The issue is related to Stored Cross-Site Scripting via the plugin's shortcodes due to insufficient input sanitization and output escaping on user-supplied attributes like before and after. This allows 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.

Recommendations For versions up to, and including, 1.6, consider disabling the shortcodes feature until a patch is available to prevent exploitation. Restrict access to the before and after attributes to minimize the risk of arbitrary web script injection. Update to a version that includes the necessary input sanitization and output escaping fixes for the shortcodes.
