CVE-2025-52655 identifies a security weakness in HCL MyXalytics version 6.6, specifically categorized under CWE-829: Inclusion of Functionality from Untrusted Control Sphere. The vulnerability arises because the application loads third-party scripts without performing integrity checks or validating their source. This lack of validation allows potentially malicious external code to run within the application's context, which can lead to unauthorized actions or data exposure. Although the vulnerability does not directly compromise confidentiality or availability, it poses a risk of integrity loss if an attacker can trick users into triggering the execution of malicious scripts. The CVSS 3.1 score of 3.1 reflects a low severity, mainly due to the requirement for user interaction and the high complexity of exploitation. No patches or known exploits have been published yet, indicating that the vulnerability is newly disclosed and not actively exploited. The vulnerability's nature suggests that attackers would need to convince users to interact with malicious content that loads untrusted scripts, which could be leveraged in targeted phishing or social engineering campaigns. The absence of authentication requirements means that any user can be targeted, but the attack complexity and user interaction reduce the overall risk. Organizations relying on HCL MyXalytics 6.6 should monitor for updates and consider additional controls to mitigate the risk of script injection or execution from untrusted sources.

For European organizations, the primary impact of this vulnerability lies in the potential execution of unauthorized third-party scripts within HCL MyXalytics, which could lead to data integrity issues or limited data exposure. Although the CVSS score is low, the risk increases in environments where sensitive analytics data is processed or where users have elevated privileges within the application. Exploitation could facilitate targeted attacks such as phishing or social engineering to execute malicious scripts, potentially leading to lateral movement or data manipulation. The lack of direct confidentiality or availability impact reduces the immediate threat level, but organizations handling regulated or sensitive data should consider the risk of indirect consequences, including compliance violations or reputational damage. Since no known exploits are in the wild, the threat is currently theoretical but warrants proactive mitigation to prevent future exploitation. The impact is more pronounced in sectors relying heavily on analytics platforms for decision-making, such as finance, healthcare, and government agencies within Europe.

To mitigate CVE-2025-52655, European organizations should implement the following specific measures: 1) Restrict the loading of third-party scripts in HCL MyXalytics by configuring Content Security Policy (CSP) headers to allow only trusted domains and prevent unauthorized script execution. 2) Employ subresource integrity (SRI) checks where possible to ensure that any third-party scripts loaded have not been tampered with. 3) Educate users on the risks of interacting with untrusted links or content that could trigger malicious script loading within the application. 4) Monitor application logs and network traffic for unusual script loading activities or external requests originating from the analytics platform. 5) Engage with HCL support to obtain patches or updates addressing this vulnerability as they become available. 6) Consider isolating the analytics environment or limiting user privileges to reduce the potential impact of malicious script execution. 7) Regularly review and update third-party integrations and dependencies to ensure they adhere to security best practices. These targeted actions go beyond generic advice by focusing on script control, user awareness, and environment hardening specific to the vulnerability context.
