The CVSS score for this vulnerability is 8.1, emphasizing its critical nature and the potential risks to affected systems.
Risk to organizations includes unauthorized access to sensitive data and system compromise. Exploitation of this vulnerability can occur remotely over the network, making it particularly dangerous. The complexity of the attack is rated as high, meaning that while the exploitation may require some technical skill, the consequences can be severe. Organizations using the Muzicon theme are encouraged to take this threat seriously and prioritize remediation efforts.
As of now, the status of this vulnerability is deferred, and there is currently no known public exploit or proof of concept available. However, organizations should remain vigilant and monitor for any updates regarding this vulnerability. Given its high CVSS score, it is crucial for organizations to implement necessary security updates and patches as they become available.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Implementing robust security practices and regularly updating software can help prevent potential exploitation.
Vulnerability Details
The vulnerability, described as 'Improper Control of Filename for Include/Require Statement in PHP Program', affects ThemeREX Muzicon versions up to 1.9.0. It is classified under CWE-98, indicating that it allows local file inclusion, which can lead to severe security issues.
This vulnerability has a CVSS score of 8.1, categorizing it as high severity. The attack vector is network-based, with high complexity and no privileges required for exploitation. There is no user interaction necessary to trigger the vulnerability, making it a significant threat to installations of the affected software.
Technical Analysis
The root cause of CVE-2026-28107 lies in the inadequate validation of user-supplied input when constructing file paths within the PHP application. This improper control allows attackers to include and execute arbitrary files from the server filesystem.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The complexity of exploiting this vulnerability is rated as high, as it requires knowledge of the application's file structure and execution context. No privileges are required for exploitation, and user interaction is not necessary, making it a straightforward attack for skilled adversaries.
Once exploited, this vulnerability can lead to high impacts on confidentiality, integrity, and availability, as attackers may gain access to sensitive files, modify application behavior, or even disrupt service availability.
Risk & Impact Analysis
Organizations deploying the ThemeREX Muzicon should understand the associated risks. The potential blast radius is significant due to the nature of local file inclusion vulnerabilities, where an attacker could access sensitive configuration files, obtain credentials, or execute code remotely.
Given the high CVSS score of 8.1, this vulnerability should be treated with utmost urgency. Organizations must address this vulnerability in their priority patch cycle to mitigate potential exploitation risks.
The EPSS score for this vulnerability is 0.00165, placing it in the 0.37137 percentile, indicating a low probability of exploitation in the near term. However, organizations should not become complacent, as the potential impact remains high.
