The CVE-2026-24630 vulnerability pertains to an improper neutralization of input during web page generation, specifically categorized as a cross-site scripting (XSS) vulnerability. This vulnerability allows for stored XSS attacks within the Design Stylish Cost Calculator plugin, affecting versions up to and including 8.2.9. The severity level is classified as medium, with a CVSS score of 6.5, indicating a notable risk that organizations must address promptly.
The potential risk to organizations includes unauthorized access to sensitive user information and the ability to execute malicious scripts in the context of the user's browser. Given the nature of stored XSS, if successfully exploited, attackers may leverage this vulnerability to manipulate web content, redirect users, or perform actions on behalf of the victims.
Currently, there is no public exploit confirmed, and the status of this vulnerability is marked as deferred. This means that while it has been identified, it may not yet be actively exploited in the wild. However, organizations using the affected versions should not wait for active exploitation but instead prioritize mitigation.
Organizations should address this vulnerability as part of their immediate risk management efforts. It is recommended to upgrade to the latest version of the plugin or apply any available patches to mitigate the risk of exploitation.
Vulnerability Details
CVE-2026-24630 is characterized by an improper neutralization of input during web page generation, specifically allowing stored XSS attacks. The vulnerability impacts the Design Stylish Cost Calculator plugin, with affected versions identified as those from n/a up to and including 8.2.9. The CVSS score of 6.5 indicates a medium severity, highlighting the need for organizations to take this seriously. The official CWE classification for this vulnerability is CWE-79.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input during the generation of web pages, which fails to adequately sanitize or validate data before rendering it. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is classified as low, requiring minimal effort to exploit, while the privileges required are low, indicating that a standard user could potentially exploit this vulnerability. User interaction is required, as the victim must interact with the malicious payload.
In terms of impacts, the confidentiality, integrity, and availability are all at low risk, as the nature of the attack primarily affects user experience and trust rather than system stability or security. The vulnerability can lead to unauthorized actions being performed on behalf of the user, which can further escalate into more severe attacks if sensitive data is compromised.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-24630 is significant, particularly for organizations that rely on the Design Stylish Cost Calculator for e-commerce or user-interactive applications. Attackers may leverage this vulnerability to deploy malicious scripts that could capture sensitive user data, manipulate web content, or redirect users to harmful sites.
Given the medium severity rating and the potential impact on user trust and data integrity, organizations are urged to prioritize the patching of this vulnerability. The current status in the KEV catalog indicates that it is not actively exploited; however, the potential for exploitation remains. Organizations should assess their exposure and readiness to address this vulnerability as part of a broader risk management strategy.
