CVE-2025-40587 in Polarion V2404
Summary
by MITRE • 02/10/2026
A vulnerability has been identified in Polarion V2404 (All versions < V2404.5), Polarion V2410 (All versions < V2410.2). The affected application allows arbitrary JavaScript code be included in document titles. This could allow an authenticated remote attacker to conduct a stored cross-site scripting attack by creating specially crafted document titles that are later viewed by other users of the application.

This vulnerability exists within Polarion software versions prior to specific patch releases, creating a significant security risk through stored cross-site scripting capabilities. The flaw allows authenticated attackers to inject malicious JavaScript code into document titles, which then executes when other users view these documents. This represents a classic stored XSS vulnerability that can be exploited to compromise user sessions and execute arbitrary code within the victim's browser context. The vulnerability affects multiple version streams including V2404 and V2410, indicating it is a widespread issue across the product line. The attack requires only authentication to the application, making it particularly dangerous as it can be executed by legitimate users with appropriate privileges. The security implications extend beyond simple script execution since the injected code can access session cookies, steal user credentials, or redirect users to malicious sites. This vulnerability directly maps to CWE-79 which defines cross-site scripting as the injection of malicious code into web applications. The ATT&CK framework categorizes this under T1059.007 for command and scripting interpreter, specifically JavaScript, and T1531 for account access tokens, as the attack can lead to session hijacking. The exploitation pathway demonstrates how legitimate application features can become attack vectors when proper input validation and output encoding are not implemented.
The technical implementation of this vulnerability occurs at the input sanitization layer where document title fields fail to properly validate or escape user-supplied data before storage. When users create documents with specially crafted titles containing JavaScript code, the application stores this data without adequate sanitization. Upon subsequent viewing of these documents, the stored JavaScript executes in the browser context of other users who access the application. This creates a persistent threat where the malicious code can affect multiple users over time, unlike reflected XSS attacks that require specific user interaction with malicious links. The vulnerability is particularly concerning because document titles are often displayed in various contexts including search results, document lists, and navigation menus, providing multiple execution points for the injected code. The attack can be amplified through social engineering techniques where attackers create seemingly legitimate document titles that contain malicious payloads. The authentication requirement reduces the attack surface compared to fully public vulnerabilities but does not eliminate the risk entirely since authenticated users may have elevated privileges within the application environment. Security controls that should have prevented this include proper HTML sanitization, input validation, and output encoding mechanisms.
The operational impact of this vulnerability extends beyond immediate code execution to encompass potential data breaches, session hijacking, and privilege escalation attacks. An attacker could use this vulnerability to access sensitive project data, modify document contents, or even escalate privileges within the application if the user has administrative rights. The stored nature of the vulnerability means that the attack persists over time, potentially affecting numerous users without requiring repeated exploitation attempts. Organizations using affected Polarion versions face risks to their development workflows, as malicious code injection could disrupt project management processes and compromise intellectual property. The vulnerability can be exploited to create backdoors or establish persistent access points within the application environment. Business continuity is threatened as the attack can lead to unauthorized access to critical project documentation and collaboration features. The impact is particularly severe in environments where Polarion is used for managing sensitive software development projects, compliance documentation, or proprietary business information. Organizations may experience regulatory compliance issues if sensitive data is accessed through this vulnerability, as it represents a failure in the application's security controls. The attack vector also enables phishing and social engineering campaigns where users may be tricked into viewing malicious documents that contain the injected JavaScript payloads.
Mitigation strategies for this vulnerability should include immediate patching to versions V2404.5 and V2410.2 where the issue has been resolved. Organizations should implement input validation controls that sanitize all user-supplied data, particularly in fields that are later rendered in web contexts. Output encoding should be implemented to prevent JavaScript execution in document titles and other user-generated content. Security teams should conduct regular vulnerability assessments to identify similar injection points within the application. Network segmentation and monitoring can help detect unusual user behavior that might indicate exploitation attempts. Access controls should be reviewed to ensure that only authorized users have the ability to create documents that could contain malicious payloads. Security awareness training for users can help prevent social engineering attacks that might leverage this vulnerability. Regular security audits should verify that proper sanitization mechanisms are in place and functioning correctly. The implementation of web application firewalls can provide additional protection layers against XSS attacks. Organizations should also consider implementing automated security scanning tools that can identify similar vulnerabilities in other parts of their application infrastructure. Incident response procedures should be updated to include detection and response protocols for XSS attacks, ensuring that security teams can quickly identify and remediate exploitation attempts. Regular security assessments should be conducted to ensure that all input validation and output encoding mechanisms remain effective against evolving attack techniques.
