CVE-2025-52624 identifies a vulnerability in HCL AION version 2.0 related to the bypass of the script allowlist configuration, specifically due to an incorrectly configured Content-Security-Policy (CSP) header. CSP is a critical security mechanism designed to restrict the sources from which scripts can be loaded and executed in web applications, thereby mitigating risks such as cross-site scripting (XSS) and other injection-based attacks. In this case, the misconfiguration allows unauthorized scripts to execute despite the presence of a script allowlist, effectively bypassing the intended security controls. This vulnerability is classified under CWE-1032, which pertains to improper enforcement of security policies. The CVSS v3.1 base score is 5.4 (medium severity), with an attack vector of network (remote exploitation), low attack complexity, no privileges required, but user interaction is necessary (e.g., victim clicking a malicious link). The impact primarily affects confidentiality and integrity, with no impact on availability. No patches or exploits are currently publicly available, but the vulnerability poses a risk if exploited, potentially allowing attackers to execute malicious scripts that could steal sensitive information or manipulate application behavior. Organizations running HCL AION 2.0 should audit their CSP headers and ensure strict enforcement of script allowlists to prevent unauthorized script execution.

For European organizations, the vulnerability could lead to unauthorized script execution within HCL AION 2.0 applications, potentially exposing sensitive data or enabling manipulation of application workflows. This can compromise confidentiality and integrity of data processed or displayed by the application. While availability is not impacted, the risk of data leakage or session hijacking could have regulatory and reputational consequences, especially under GDPR. Organizations in sectors such as finance, healthcare, and government using HCL AION 2.0 are particularly at risk due to the sensitive nature of their data and the criticality of their applications. The need for user interaction reduces the likelihood of widespread automated exploitation but targeted phishing or social engineering attacks could leverage this vulnerability. The absence of known exploits in the wild currently limits immediate risk but proactive mitigation is essential to prevent future exploitation.

European organizations should immediately audit and correct the Content-Security-Policy headers in their HCL AION 2.0 deployments to ensure strict enforcement of script allowlists. This includes explicitly specifying trusted script sources and avoiding overly permissive directives such as 'unsafe-inline' or wildcard sources. Implementing nonce- or hash-based CSP policies can further strengthen script validation. Regularly review and update CSP configurations as part of the secure development lifecycle and deployment processes. Additionally, organizations should educate users about the risks of interacting with untrusted links or content to reduce the likelihood of successful social engineering attacks. Monitoring web application logs for unusual script execution patterns and employing web application firewalls (WAFs) with CSP enforcement capabilities can provide additional layers of defense. Finally, stay alert for vendor patches or updates from HCL and apply them promptly once available.
