Deeper analysis

CVE-2026-28009 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98 and described as enabling PHP Local File Inclusion, in the ThemeREX DroneX WordPress theme. This issue affects all versions of DroneX from n/a through 1.1.12. 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 its potential for significant impact across confidentiality, integrity, and availability.

Remote, unauthenticated attackers can exploit this vulnerability over the network with high attack complexity and no user interaction required. Exploitation allows inclusion of local PHP files, potentially leading to arbitrary code execution, sensitive data disclosure, or system compromise, aligning with the high impact ratings in the CVSS vector.

prevent

Requires timely remediation of known flaws like the LFI vulnerability in DroneX theme versions <=1.1.12 to prevent exploitation via improper filename control in PHP include/require.

prevent

Mandates validation of user-supplied inputs used as filenames in PHP include/require statements to block local file inclusion attacks.

prevent

Enforces secure configuration settings in PHP environments, such as open_basedir restrictions, to limit arbitrary local file access exploitable by this LFI vulnerability.
