Organizations using ThemeREX Ozisti should assess their usage and apply the necessary patches immediately to mitigate exposure. The vulnerability was published on March 5, 2026, and has been categorized as deferred, indicating ongoing assessment of its impact.
Due to the potential for exploitation, it is critical that organizations prioritize remediation efforts in their patch management cycles.
Vulnerability Details
The vulnerability in ThemeREX Ozisti is defined as an 'Improper Control of Filename for Include/Require Statement in PHP Program', which falls under the category of PHP Remote File Inclusion. The CVSS 3.1 score is 8.1, indicating a high severity level due to the impact it can have on confidentiality, integrity, and availability.
This vulnerability affects Ozisti in versions from n/a through 1.1.10, and as such, organizations should review their versioning to ensure compliance and patching.
Technical Analysis
The root cause of CVE-2026-28093 stems from the improper control of file inclusion in PHP scripts. This vulnerability allows attackers to execute arbitrary PHP code by including local files, which can lead to full system compromise depending on the sensitivity of the included files.
The attack vector for this vulnerability is the network, requiring no user interaction. The complexity of the attack is classified as high, which means that while exploitation is possible, it may require specific conditions to be met. The privileges required for exploitation are none, making it more accessible to potential attackers.
The confidentiality impact is high, indicating that sensitive information could be exposed. Similarly, the integrity and availability impacts are also high, meaning that an attacker could manipulate or make systems unavailable. Therefore, organizations should be vigilant about monitoring their systems for any signs of exploitation.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-28093 is significant, particularly for organizations relying on ThemeREX Ozisti. The potential for unauthorized access to sensitive files poses a critical risk to organizational security. Given the high CVSS score and the nature of the vulnerability, organizations must take immediate action to patch affected systems.
The vulnerability's blast radius could be extensive, especially in cases where the theme is widely deployed across multiple sites. As such, the urgency for organizations to address this issue is high, and they should incorporate it into their priority patch cycle.
