Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in ThemeREX Daiquiri daiquiri allows PHP Local File Inclusion.This issue affects Daiquiri: from n/a through <= 1.2.4.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly mitigates the improper filename control in PHP include/require by enforcing validation of user-supplied inputs to prevent local file inclusion.

SI-2 Flaw Remediation good match
prevent

Requires timely remediation of the specific LFI flaw in the Daiquiri WordPress theme through patching or upgrades beyond version 1.2.4.

CM-6 Configuration Settings partial match
prevent

Enforces secure configuration settings in PHP, such as open_basedir or disabling allow_url_include, to restrict arbitrary file access even if input validation fails.

Security SummaryAI

CVE-2026-28089 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as a PHP Remote File Inclusion issue that enables PHP Local File Inclusion, affecting the ThemeREX Daiquiri WordPress theme. This flaw impacts all versions from n/a through 1.2.4 and is associated with CWE-98. Published on 2026-03-05, it 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.

Unauthenticated attackers (PR:N) can exploit this vulnerability remotely over the network (AV:N) without requiring user interaction (UI:N), though it demands high attack complexity (AC:H). Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged security scope (S:U), potentially enabling attackers to read local files or escalate to more severe outcomes depending on the included files.
