CVE-2026-28081 is a high-severity vulnerability affecting ThemeREX Windsor versions up to 2.5.0. This vulnerability allows improper control of filename for include or require statements in PHP programs, leading to PHP Local File Inclusion. The attack vector is network-based, and it requires no user interaction or privileges to exploit. Organizations utilizing this theme should assess their exposure and implement remediation measures quickly.
With a CVSS score of 8.1, this vulnerability poses significant risks to confidentiality, integrity, and availability, making it crucial for affected organizations to prioritize patching immediately.
The vulnerability was published on March 5, 2026, and has been classified as deferred status. It is essential for organizations to follow up on patch availability and ensure that their systems are updated accordingly.
Risk to organizations includes unauthorized access to sensitive files on the server due to this vulnerability. Attackers may leverage this flaw to execute malicious scripts, potentially leading to data breaches or service disruptions.
Currently, there is no confirmed public exploit or proof of concept available. However, the high exploitability score indicates that this vulnerability could be targeted if not addressed.
Vulnerability Details
The vulnerability involves improper control of filename for include and require statements in PHP scripts within ThemeREX Windsor. The affected versions are from n/a through version 2.5.0, as indicated in the CVE description.
Classified under CWE-98, this vulnerability allows attackers to include files that should be restricted, potentially exposing sensitive data and enabling further attacks.
The published CVSS score of 8.1 reflects a high severity level, indicating the need for urgent action. The attack vector is network-based, with high attack complexity, meaning that while it may not be easily exploitable, the consequences of a successful attack could be severe.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of input used in PHP include/require statements. This flaw can lead to local file inclusion, where an attacker can manipulate the input to include arbitrary files on the server.
The attack vector is network-based, requiring no user interaction. Attack complexity is classified as high, indicating that while the vulnerability exists, successfully exploiting it may require specific conditions or knowledge.
No privileges are required for exploitation, meaning any unauthenticated user could potentially exploit this vulnerability. User interaction is not necessary, which increases the risk of widespread exploitation.
The vulnerability has high impacts across confidentiality, integrity, and availability, making it a critical concern for organizations using the affected version of ThemeREX Windsor.
Risk & Impact Analysis
Organizations that deploy ThemeREX Windsor could face significant risks due to this vulnerability. The potential for unauthorized access to sensitive files can result in data breaches, leading to legal and financial repercussions.
Given the high CVSS score, it is crucial for organizations to address this vulnerability promptly. The attack vector's network-based nature allows for remote exploitation, which heightens the urgency for remediation.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The potential blast radius includes any system utilizing the affected versions, emphasizing the need for a comprehensive risk management strategy.
