Technical summary

The CVE-2025-69162 vulnerability is caused by an unauthenticated local file inclusion (LFI) weakness in the Grecko theme, versions <= 5.17. This allows attackers to manipulate file paths and potentially read or execute sensitive files on the server. The vulnerability is characterized by the following CVSS vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. This indicates that the vulnerability can be exploited remotely (AV:N), requires high attack complexity (AC:H), does not require any privileges (PR:N), and can lead to high impacts on confidentiality, integrity, and availability.

Defensive priority

HIGH

Recommended defensive actions

  • Update the Grecko theme to a version that is not vulnerable (if available).
