Vulnerability Details

The official description states that this vulnerability allows improper control of filename for include/require statements in PHP programs. It affects ThemeREX DroneX from n/a to version 1.1.12. The vulnerability is categorized under CWE-98, which pertains to improper control of filename for include/require statement in PHP.

The CVSS version is 3.1, with a vector string of CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. The impacts on confidentiality, integrity, and availability are all rated as high, indicating a serious risk to the affected systems.

Technical Analysis

The root cause of this vulnerability is the improper control of filenames in PHP include/require statements. Attackers can exploit this by manipulating the input to include files that should not be accessible, potentially leading to disclosure of sensitive information.

The attack vector is network-based, meaning that an attacker does not need physical access to the target system. The attack complexity is rated as high, indicating that it requires special conditions to exploit, such as knowledge of the file structure or the ability to manipulate input correctly.

No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impacts on confidentiality, integrity, and availability are all rated as high, reflecting the serious nature of the potential consequences.

Risk & Impact Analysis

The real-world deployment risk of CVE-2026-28009 is significant. Organizations using the affected versions of ThemeREX DroneX are exposed to potential unauthorized access to sensitive data. The blast radius could affect any application relying on this theme, making the need for immediate remediation critical.

Given the CVSS score of 8.1 and the absence from the KEV catalog, organizations should still treat this vulnerability with high urgency and address it in their patch cycles.

The low EPSS score of 0.00165 indicates that while this vulnerability might not be actively exploited in the wild, the potential for exploitation remains, especially given its high impact.

Affected Versions
