Detection Guidance

This vulnerability involves missing authorization checks in the Royale News WordPress theme up to version 2.2.4, allowing unauthenticated users to perform privileged actions. Detection typically involves checking if the vulnerable theme version is in use and monitoring for unauthorized access attempts.

Since the vulnerability is related to broken access control in theme functions, you can detect it by identifying the theme version and looking for suspicious HTTP requests attempting to access restricted theme functionalities without proper authentication.

• Check the installed theme version by running a command to list WordPress themes and their versions, for example using WP-CLI: `wp theme list`.
• Search web server logs for unusual or unauthorized requests targeting theme-specific endpoints or parameters that could exploit missing authorization.
• Use network monitoring tools or intrusion detection systems to flag HTTP requests that attempt to perform privileged actions without authentication.

No specific detection commands are provided in the available resources, but the above general approaches can help identify the presence and exploitation attempts of this vulnerability.
