A vulnerability has been found in nextlevelbuilder ui-ux-pro-max-skill up to version 2.5.0. This vulnerability allows cross-site scripting (XSS) attacks, which can be executed remotely. The affected function is data.get, located in the file .claude/skills/design-system/scripts/generate-slide.py of the component Slide Generator. The exploit has been disclosed to the public and may be used. Despite early notification through a pull request, the project maintainers have yet to address this issue.
Given the nature of this vulnerability, organizations using this component should be vigilant. The CVSS score of 2.1 indicates a low severity, but it is essential to recognize that vulnerabilities, even those classified as low, can still pose risks depending on the context of their deployment.
Risk to organizations includes potential unauthorized access to user data and manipulation of web application behavior. Therefore, organizations should assess their exposure to this vulnerability and take appropriate action to mitigate risks, particularly if they are operating in environments where user input is processed.
Organizations should prioritize patching immediately. Regular updates and security assessments can help minimize the impact of such vulnerabilities.
Vulnerability Details
The vulnerability allows attackers to perform cross-site scripting through the manipulation of the data.get function within the Slide Generator component. The CVSS score assigned to this vulnerability is 2.1, indicating a low severity level. This score reflects low attack complexity and the potential for user interaction, positioning the vulnerability within a manageable risk category.
The publication date for this vulnerability was May 1, 2026. It is categorized under the Common Weakness Enumeration (CWE) identifiers CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Code Injection).
Technical Analysis
The root cause of this vulnerability lies in inadequate input validation within the affected function. Attackers may exploit this by injecting malicious scripts into the web application, which can then execute within the user's browser.
The attack vector is primarily network-based, allowing remote exploitation. The complexity of the attack is assessed as low, requiring no special privileges for successful exploitation. User interaction is required, as the victim must access a webpage that includes the malicious script.
The impact on confidentiality is negligible, while the integrity impact is classified as low. Availability is not affected by this vulnerability.
Risk & Impact Analysis
Organizations utilizing nextlevelbuilder ui-ux-pro-max-skill should understand the implications of this vulnerability. While the CVSS score indicates a low severity, the potential for exploitation remains a concern, especially in applications where user-generated content is prevalent.
The blast radius could extend to any users of the application, making it critical for organizations to assess their risk exposure. The urgency of addressing this vulnerability is high, given the potential for unauthorized manipulation of the application through XSS.
Organizations should schedule remediation as part of their patch management processes to ensure vulnerabilities are addressed before they can be exploited. This includes evaluating their current security posture and implementing necessary updates.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch are affected, specifically up to version 2.5.0 of nextlevelbuilder ui-ux-pro-max-skill.
Mitigation & Remediation
Organizations should monitor for updates from the vendor and apply patches as soon as they are available. Configuration hardening should also be implemented to minimize the risk of XSS vulnerabilities in web applications.
If immediate patching is not feasible, consider employing web application firewalls (WAFs) to filter out potential XSS attacks. Additionally, conducting regular security assessments can help identify other vulnerabilities.
Organizations should validate remediation through penetration testing to identify similar weaknesses.
Detection Guidance
Monitoring logs for unusual behavior and potential script injections is essential. Look for unauthorized changes in user-generated content and track any anomalies in user interactions.
Implementing network signatures to detect patterns associated with XSS attacks can be beneficial. Additionally, changes to system files related to the Slide Generator component should be closely monitored.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2026-7596 highlights the ongoing risks of insufficient input validation in web applications. Developers should prioritize proper input sanitization to prevent similar vulnerabilities.
