Deeper analysis

CVE-2026-28085 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, described as PHP Remote File Inclusion but enabling PHP Local File Inclusion, in the ThemeREX Mahogany WordPress theme. This issue affects Mahogany versions from n/a through <= 2.9 and is associated with CWE-98. The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility and significant impacts.

Remote unauthenticated attackers (PR:N) can exploit this vulnerability over the network (AV:N), though it requires high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation allows high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), potentially enabling attackers to include and execute arbitrary local PHP files, leading to server compromise such as code execution or data disclosure.
