CVE-2023-45652Network attack vector

Authenticated file disclosure via unrestricted shortcode URL

Published May 17, 2024 · Updated Apr 28, 2026

Local file inclusion in Remote Content Shortcode 1.5 and earlier allows remote authenticated users to read server files via a crafted shortcode URL. The remote_content_shortcode method passes the shortcode's unvalidated url attribute to cURL as CURLOPT_URL, so file-scheme paths return local file contents. Contributor-level access is required to submit the shortcode; disclosure is limited to files readable by the WordPress PHP process.
