Published Mar 13, 2024

Summary

CVE-2023-6809 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Custom fields shortcode plugin for WordPress. The issue lies in the plugin's cf shortcode, which fails to adequately sanitize and escape user-supplied custom post meta values. This oversight enables authenticated attackers with contributor-level or higher permissions to inject arbitrary web scripts. These scripts are executed whenever a user accesses a page containing the injected content, potentially leading to unintended website functionality or data theft. Versions of the plugin up to and including 0.1 are vulnerable to this exploit.
