Deeper analysis

CVE-2025-69099 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the North WordPress theme (north-wp) developed by fuelthemes. The flaw allows Object Injection and affects all versions of the North theme from n/a through 5.7.5. Published on 2026-01-22, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.

Low-privileged remote attackers (PR:L) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction required (UI:N). Successful exploitation enables high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged security scope (S:U), typically through PHP object injection leading to arbitrary code execution or other severe compromises on affected WordPress sites.
