CVE-2026-28128 is a high-severity vulnerability that affects the ThemeREX Verse WordPress theme. This vulnerability allows for improper control of filename for include/require statements, leading to PHP local file inclusion. The flaw is present in versions of Verse from n/a through 1.7.0. With a CVSS score of 8.1, it poses a significant risk to organizations using the affected versions.
The vulnerability is classified under CWE-98, indicating that it allows attackers to control the filename parameter, which can lead to unauthorized access to sensitive files on the server. Given the nature of the flaw, organizations should assess their usage of the ThemeREX Verse theme and prepare for immediate remediation.
Risk to organizations includes potential exposure of sensitive information and the ability for attackers to execute arbitrary code within the server environment. The attack vector is classified as network-based, and the complexity is high, meaning that successful exploitation may require a specific set of conditions.
With the vulnerability being marked as deferred, it is crucial for security teams to monitor any updates from the vendor and address this vulnerability in their patch cycle. Organizations should prioritize patching immediately to prevent potential exploitation.
Vulnerability Details
The CVE-2026-28128 vulnerability is defined as an improper control of filename for include/require statement in a PHP program, specifically affecting ThemeREX Verse version 1.7.0 and earlier. The CVSS score of 8.1 indicates a high severity level, which emphasizes the need for organizations to take this issue seriously.
The vulnerability allows attackers to exploit the server by including arbitrary files, potentially leading to full system compromise. The attack complexity is high, and it does not require any privileges or user interaction. Thus, the impact on confidentiality, integrity, and availability is rated as high.
Technical Analysis
The root cause of CVE-2026-28128 lies in the improper handling of filenames in the PHP include/require statements. This flaw allows attackers to manipulate the filename parameter, leading to local file inclusion vulnerabilities. The attack vector is network-based, whereby an attacker can initiate an attack remotely.
The attack complexity is high due to the specific conditions required for exploitation. No privileges are required to exploit this vulnerability, and no user interaction is needed. However, the high attack complexity suggests that an attacker may need to perform specific actions to successfully exploit the vulnerability.
The impacts of this vulnerability are severe, with high potential for unauthorized access to sensitive information. The confidentiality, integrity, and availability impacts are all rated high, indicating that successful exploitation can lead to significant data breaches and service disruption.
Risk & Impact Analysis
Organizations using the affected versions of ThemeREX Verse face significant risks. Given the high severity of CVE-2026-28128, the potential for exploitation is a serious concern. Attackers may leverage this vulnerability to gain unauthorized access, potentially leading to data leakage or system compromise.
The blast radius for this vulnerability could be extensive, particularly for organizations hosting sensitive data on their systems. Organizations should assess their exposure and implement necessary controls to mitigate risks arising from this vulnerability.
With the CVSS score indicating high severity and the potential impact on confidentiality and integrity, organizations must prioritize addressing this vulnerability in their patch cycle. The urgency for remediation is critical to prevent exploitation.
