CVE-2026-13083 in Pen Drive Powered by Lightspeed
Summary
by MITRE • 06/26/2026
A flaw was found in the Pen Drive report generator. Cluster-sourced data is rendered into HTML reports without proper escaping or sanitization. An attacker with cluster administrator privileges can inject a stored cross-site scripting (XSS) payload into cluster objects (such as ClusterVersion spec.channel) that executes in the browser of any user who opens the generated HTML report.

This vulnerability exists within the Pen Drive report generator component where cluster-sourced data is processed and rendered into HTML output without adequate input validation or output sanitization measures. The flaw stems from improper handling of user-supplied data that originates from cluster administrator interactions, specifically targeting objects such as ClusterVersion spec.channel which contain configuration parameters that can be manipulated by privileged users. The vulnerability manifests as a stored cross-site scripting weakness that allows an attacker with cluster administrator privileges to inject malicious JavaScript code into cluster metadata that persists and executes whenever any user views the generated HTML report. This represents a critical security flaw that aligns with CWE-79 (Cross-site Scripting) and follows the ATT&CK technique T1059.006 (Command and Scripting Interpreter: PowerShell) through the execution of malicious scripts within the browser context. The attack vector leverages the trust relationship between cluster administrators and the reporting system, where legitimate administrative actions become vectors for malicious code injection.
The operational impact of this vulnerability extends beyond simple data compromise as it enables attackers to execute arbitrary code within the browser context of any user who accesses affected reports. This creates persistent threat vectors that can be used for credential theft, session hijacking, or redirection to malicious sites. The stored nature of the XSS payload means that the attack remains effective even after the initial injection point is no longer active, allowing attackers to maintain access over extended periods without requiring repeated exploitation attempts. Users who routinely access cluster reports become unwitting participants in the attack chain, making this vulnerability particularly dangerous in environments with multiple administrators or shared reporting systems.
Mitigation strategies should focus on implementing comprehensive input validation and output sanitization mechanisms throughout the report generation pipeline. All user-supplied data must be properly escaped or sanitized before being rendered into HTML content, with strict adherence to security standards such as those outlined in OWASP Top Ten and NIST SP 800-171. The system should implement Content Security Policy headers to limit script execution capabilities within the report viewer environment. Additionally, privilege separation should be enforced where possible, ensuring that administrative actions cannot directly influence report generation without proper validation and sanitization processes. Regular security testing including automated scanning for XSS vulnerabilities and manual penetration testing of report generation components should be implemented as part of ongoing security monitoring activities. The vulnerability also highlights the need for secure coding practices that prevent the direct inclusion of untrusted data into executable contexts, reinforcing principles from the ATT&CK framework's defense evasion categories and ensuring compliance with security standards such as those recommended in ISO 27001 and CIS Controls.
