The issue impacts all versions from n/a through 1.0.2 and is associated with CWE-98.

Unauthenticated remote attackers (AV:N/PR:N/UI:N) can exploit this vulnerability over the network, though it requires high attack complexity (AC:H). Successful exploitation can result in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), with an overall CVSS v3.1 base score of 8.1 and unchanged scope (S:U), potentially allowing attackers to include and execute arbitrary local files on the server.
