The vulnerability CVE-2025-69398 in ThemeREX Plank arises from improper validation of filenames used in PHP include or require statements, resulting in a Local File Inclusion issue. This allows an attacker to cause the application to include unintended local files, potentially leading to arbitrary code execution or information disclosure. The affected versions are from initial releases through version 1.7. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to local file inclusion, which may allow attackers to execute arbitrary code, disclose sensitive information, or cause denial of service on the affected system. The high CVSS score reflects the critical nature of these impacts. There are no reports of active exploitation in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the affected application and monitor for suspicious activity related to file inclusion attempts. Avoid exposing the vulnerable application to untrusted networks if possible.
