The vulnerability CVE-2025-63036 affects the Ronneby Theme Core by DFDevelopment, specifically versions up to and including 1.5.68. It involves improper control of the filename parameter used in PHP include or require statements, resulting in a Local File Inclusion (LFI) vulnerability. This can allow an attacker with limited privileges to include arbitrary files on the server, potentially leading to remote code execution or disclosure of sensitive information. The CVSS 3.1 base score is 7.5, reflecting network attack vector, high impact on confidentiality, integrity, and availability, and requiring low privileges without user interaction. No cloud service is involved, and no patch or vendor advisory is currently available.

Successful exploitation of this vulnerability can lead to local file inclusion, which may allow attackers to execute arbitrary code, access sensitive files, or disrupt service availability. The CVSS score of 7.5 indicates a high impact on confidentiality, integrity, and availability. However, no known exploits have been reported in the wild so far.

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 vulnerable versions of the Ronneby Theme Core and monitor for updates from DFDevelopment. Avoid exposing the affected component to untrusted inputs that could be used to manipulate include/require statements.
