This vulnerability, identified as CWE-98, arises from improper control of filenames in PHP include/require statements within THEMELOGI Roneous versions <= 2.1.5. An unauthenticated attacker can exploit this local file inclusion flaw to execute arbitrary code by including malicious files. The CVSS 3.1 base score is 8.1, reflecting high impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available, and no known exploits have been reported in the wild.

Successful exploitation can lead to remote code execution, full compromise of the affected system, and complete loss of confidentiality, integrity, and availability of the application and underlying server. Because the vulnerability is unauthenticated, it can be exploited by any remote attacker without credentials.

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