CVE-2026-28130 is a high-severity vulnerability categorized as improper neutralization of input during web page generation, specifically a reflected cross-site scripting (XSS) vulnerability. This issue affects the AndonDesign UDesign theme, allowing attackers to exploit the vulnerability in versions up to 4.14.0. The CVSS score for this vulnerability is 7.1, indicating a high severity level that necessitates prompt remediation by affected organizations.
The risk to organizations includes potential unauthorized access to sensitive information through the execution of malicious scripts in the user's browser. As the vulnerability is classified as reflected XSS, it can be exploited through the manipulation of input data that is not properly sanitized. This could allow attackers to perform actions on behalf of users if they can trick them into clicking a malicious link.
The exploitation status for this vulnerability is currently deferred, meaning that no public exploits have been confirmed. However, the risk remains significant due to the nature of XSS vulnerabilities and the potential for abuse in real-world scenarios. Organizations using affected versions of the UDesign theme should prioritize patching immediately to mitigate any risks associated with this vulnerability.
Given the high CVSS score and the potential impact, organizations are strongly advised to review their deployment of the UDesign theme and implement necessary updates or mitigations to secure their web applications.
Vulnerability Details
The CVE-2026-28130 vulnerability allows for reflected XSS in the AndonDesign UDesign theme, affecting versions from n/a up to and including 4.14.0. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input. The CVSS score of 7.1 indicates a high-severity risk, with an attack vector of network, low attack complexity, no required privileges, and user interaction being necessary. The nature of the vulnerability and its potential impact on confidentiality, integrity, and availability is low, but the risk of exploitation remains a concern.
Technical Analysis
The root cause of CVE-2026-28130 is the failure to sanitize user input adequately during web page generation, which allows attackers to inject scripts that can be executed in the context of the victim's browser. The attack vector is network-based, requiring the victim to interact with a malicious link that exploits the vulnerability. Given the low complexity of the attack, it poses a significant risk, especially since no privileges are required for exploitation, and it necessitates user interaction.
Although the impact on confidentiality, integrity, and availability is rated as low, the implications of successful exploitation can lead to the exposure of sensitive information or further attacks on the application. Security teams should be aware of the potential for such vulnerabilities to be exploited in conjunction with other attack vectors.
Risk & Impact Analysis
Organizations using the AndonDesign UDesign theme need to assess the real-world deployment risk associated with this vulnerability. The potential blast radius could include any user of the affected theme, leading to unauthorized actions performed in the context of the victim's session. Given the high CVSS score and the current status of the vulnerability, organizations should address this vulnerability in their priority patch cycle.
The urgency to remediate CVE-2026-28130 is high due to the possibility of exploitation that could lead to data theft or further attacks. Organizations should implement mitigations and ensure their web applications are protected against this and similar vulnerabilities.
