## Technical details

A Local File Inclusion (LFI) vulnerability exists in the Select-Themes Struktur Core plugin (struktur-core) for WordPress. The flaw stems from improper validation of user-supplied input used in PHP include or require statements (CWE-98). An attacker with 'Contributor' level privileges or higher can manipulate file paths to include local files from the server's filesystem. This can lead to the disclosure of sensitive information, such as the wp-config.php file, or potentially remote code execution if the attacker can upload or find a controllable file on the server. The vulnerability affects versions up to 2.5.1; as of the advisory date, no official patch has been confirmed.
