CVE-2025-47054 is a DOM-based Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from improper handling of user-controllable input within the Document Object Model (DOM) environment, allowing an attacker with low privileges to inject and execute malicious JavaScript code in the context of a victim's browser. Exploitation requires the victim to interact with a specially crafted web page, which manipulates the DOM to trigger the malicious script execution. The vulnerability impacts confidentiality and integrity by potentially allowing attackers to steal sensitive information such as session tokens, cookies, or perform actions on behalf of the victim user. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based, requires low privileges, user interaction, and has a scope change (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. No known exploits are reported in the wild yet, and no official patches have been linked at the time of publication. The vulnerability is categorized under CWE-79, which is a common and well-understood class of XSS vulnerabilities, emphasizing the need for proper input validation and output encoding in web applications. Given that AEM is a widely used enterprise content management system, this vulnerability could be leveraged to compromise web portals, intranet sites, or customer-facing applications built on AEM platforms.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for managing critical web content and digital experiences. Successful exploitation could lead to session hijacking, unauthorized actions performed on behalf of users, and leakage of sensitive corporate or customer data. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and potential financial losses. Since AEM is often used by government agencies, financial institutions, and large enterprises in Europe, the risk extends to critical infrastructure and sensitive information systems. The requirement for user interaction means phishing or social engineering campaigns could be used to lure victims to malicious pages, increasing the attack surface. The scope change in the CVSS vector suggests that the vulnerability could affect components beyond the immediate web application, potentially impacting integrated systems or services.

European organizations should prioritize the following mitigation steps: 1) Immediately audit and inventory all instances of Adobe Experience Manager in use, focusing on versions 6.5.22 and earlier. 2) Monitor Adobe's official security advisories for patches or updates addressing CVE-2025-47054 and apply them promptly once available. 3) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious DOM manipulation patterns or payloads associated with XSS attacks targeting AEM. 4) Conduct security awareness training to educate users about the risks of clicking on untrusted links or visiting suspicious web pages, reducing the likelihood of successful user interaction exploitation. 5) Review and enhance input validation and output encoding practices within custom AEM components or extensions to minimize DOM-based XSS risks. 6) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM-managed sites. 7) Regularly perform security testing, including penetration tests and automated scanning, focusing on DOM-based XSS vectors in AEM environments. These measures, combined, will reduce the attack surface and limit the potential damage from exploitation.
