Description

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in ThemeREX Ozisti ozisti allows PHP Local File Inclusion.This issue affects Ozisti: from n/a through <= 1.1.10.

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-10 requires validation of information inputs like filenames passed to PHP include/require statements, directly preventing local file inclusion by rejecting invalid or malicious paths in the Ozisti theme.

prevent

SI-2 mandates timely flaw remediation, such as patching the vulnerable Ozisti WordPress theme versions up to 1.1.10 to eliminate the PHP local file inclusion vulnerability.

prevent

CM-6 enforces secure configuration settings like PHP open_basedir restrictions or disabling allow_url_include, limiting the impact of improper filename controls in the Ozisti theme.

Security SummaryAI

CVE-2026-28093 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 despite being labeled as a potential PHP Remote File Inclusion issue. It affects the Ozisti WordPress theme developed by ThemeREX, impacting all versions from n/a through 1.1.10. 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 network accessibility and potential for significant impacts.

Remote attackers without privileges or user interaction can exploit this flaw over the network, though it requires high attack complexity. Successful exploitation allows arbitrary local file inclusion, enabling attackers to read sensitive local files on the server, potentially leading to unauthorized access to configuration data, source code, or other critical resources, with high confidentiality, integrity, and availability impacts.
