CVE-2025-62326 is a stored cross-site scripting (XSS) vulnerability classified under CWE-79, affecting HCLSoftware's Digital Experience product, specifically version 9.5. The vulnerability resides in the administrative user interface where improper neutralization of input during web page generation allows malicious scripts to be stored and executed when viewed by other administrative users. This type of XSS is particularly dangerous because the malicious payload persists on the server and can affect multiple users. Exploitation requires the attacker to have elevated privileges (administrator-level access) and involves user interaction, such as an admin viewing a crafted page or input. The CVSS 3.1 base score of 6.1 reflects a medium severity, with attack vector being network-based, low attack complexity, but requiring high privileges and user interaction. The impact includes high confidentiality and integrity loss, as attackers can steal sensitive admin session tokens, manipulate admin interface data, or perform actions on behalf of other admins. Availability impact is rated none, as the vulnerability does not disrupt service. No public exploit code or active exploitation has been reported yet. The vulnerability was reserved in October 2025 and published in February 2026. The lack of patch links suggests that fixes may be pending or need to be obtained directly from HCLSoftware. This vulnerability highlights the need for secure coding practices in administrative interfaces, especially input validation and output encoding to prevent script injection.

The potential impact of CVE-2025-62326 is significant for organizations using HCL Digital Experience version 9.5, particularly those relying on the administrative interface for critical content management and digital operations. An attacker with administrative privileges exploiting this vulnerability can execute arbitrary scripts in the context of other admin users, leading to theft of sensitive information such as session cookies, credentials, or configuration data. This can result in unauthorized access escalation, data manipulation, and potential compromise of the entire digital experience platform. While the attack requires elevated privileges, insider threats or compromised admin accounts could leverage this flaw to expand their control or disrupt operations. The confidentiality and integrity of administrative data are at high risk, potentially affecting business continuity and trust. Since availability is not impacted, the threat is more about stealthy data breaches and manipulation rather than service disruption. Organizations in sectors with high reliance on digital experience platforms, such as government, finance, healthcare, and large enterprises, face increased risk. The absence of known exploits in the wild provides a window for proactive mitigation before active attacks occur.

To mitigate CVE-2025-62326 effectively, organizations should: 1) Immediately restrict administrative interface access to trusted personnel and networks using strong authentication and network segmentation. 2) Apply the latest security patches or updates from HCLSoftware as soon as they become available, or engage with HCL support to obtain fixes if not yet publicly released. 3) Implement strict input validation and output encoding on all user-supplied data within the admin interface to prevent script injection. 4) Conduct regular security audits and code reviews focusing on input handling in administrative modules. 5) Monitor administrative user activities and logs for unusual behavior or signs of exploitation attempts. 6) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the admin interface. 7) Educate administrators about the risks of clicking on untrusted links or opening suspicious content within the admin environment. 8) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the admin interface. These measures combined will reduce the attack surface and help detect or prevent exploitation of this vulnerability.
