CVE-2026-28068 is a high-severity vulnerability identified in the ThemeREX Rhythmo theme, specifically impacting versions up to and including 1.3.4. This vulnerability allows for PHP Local File Inclusion, which can lead to unauthorized access to sensitive files on the server. The CVSS score of 8.1 indicates a high level of risk to organizations utilizing this theme. Given the nature of the vulnerability, it is critical for affected organizations to address this issue promptly.
The exploitation of this vulnerability could potentially expose sensitive data, making it a significant threat to the security of systems relying on the Rhythmo theme. Organizations should prioritize patching immediately to minimize exposure and protect their assets.
While there are no known exploits currently available in the public domain, the nature of the vulnerability suggests that it could be leveraged by malicious actors if left unaddressed. Therefore, proactive measures should be taken to ensure that systems are updated and secure.
Organizations using the Rhythmo theme are advised to review their systems for this vulnerability and implement necessary updates to mitigate risks associated with potential exploitation.
Vulnerability Details
The vulnerability is characterized as an improper control of filename for include/require statements in PHP, commonly known as PHP Remote File Inclusion. The specific issue arises from the way the ThemeREX Rhythmo theme handles file inclusions, allowing attackers to potentially include arbitrary files from the server.
The vulnerability's CVSS score is 8.1, indicating a high severity level. This reflects a network attack vector, high attack complexity, and the absence of required privileges and user interaction for exploitation. The impacts on confidentiality, integrity, and availability are all rated as high, emphasizing the significant risk to organizations.
The vulnerability affects ThemeREX Rhythmo theme in versions n/a through <= 1.3.4. The CWE classification for this vulnerability is CWE-98.
Technical Analysis
The root cause of CVE-2026-28068 stems from improper validation of filenames in include or require statements within the PHP code of the Rhythmo theme. This flaw allows an attacker to manipulate the input and potentially include files that should not be accessible, leading to unauthorized data exposure.
The attack vector is classified as network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is rated as high due to the requirement for specific conditions to be met, such as knowledge of the system’s file structure and potential configuration settings.
Exploitation of this vulnerability does not require any privileges, nor does it require user interaction, making it easier for an attacker to execute an attack. The potential impacts include high confidentiality, integrity, and availability risks, which could lead to severe consequences for affected organizations.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive files and data exposure. Given the high severity score, there is a significant risk of exploitation if the vulnerability remains unpatched. The potential blast radius could affect not only the individual sites using the Rhythmo theme but could also pose risks to the broader systems and networks they are interconnected with.
Organizations should assess their deployment of the Rhythmo theme and consider the urgency of remediation based on the high CVSS score. Failure to patch this vulnerability could result in severe data breaches and reputational damage.
With an EPSS score indicating a 0.00165 probability of exploitation, organizations should still treat this vulnerability with high priority due to the nature of the risk involved.
