CVE-2025-47053 is a DOM-based Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises when an attacker can manipulate the Document Object Model (DOM) environment in a victim's browser to execute arbitrary JavaScript code. The attack vector requires a low-privileged attacker to craft a malicious web page or URL that, when visited by a victim, triggers the execution of the injected script within the context of the vulnerable AEM instance. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.4, reflecting a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction (victim must visit a crafted page). The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches are linked yet. This vulnerability could allow attackers to steal sensitive information such as session tokens, perform actions on behalf of the user, or manipulate the content displayed to the user, potentially leading to further attacks like phishing or privilege escalation within the application context.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security, especially for those hosting customer-facing portals, intranets, or digital asset management systems. Exploitation could lead to unauthorized disclosure of sensitive data, session hijacking, or manipulation of user interactions, undermining trust and compliance with data protection regulations such as GDPR. The requirement for user interaction means social engineering or phishing campaigns could be used to lure victims into triggering the exploit. Given the widespread adoption of Adobe Experience Manager in sectors such as government, finance, healthcare, and media across Europe, successful exploitation could disrupt business operations, damage reputation, and lead to regulatory penalties. The medium severity score reflects a moderate but tangible threat, especially in environments where AEM is integrated with critical business workflows or sensitive data repositories.

European organizations should prioritize the following mitigation steps: 1) Immediate assessment of Adobe Experience Manager versions in use to identify vulnerable instances (<=6.5.22). 2) Monitor Adobe security advisories for official patches or updates addressing CVE-2025-47053 and apply them promptly once available. 3) Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious DOM manipulation patterns or known XSS payloads targeting AEM endpoints. 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 social engineering. 5) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within AEM-hosted applications. 6) Review and sanitize all user inputs and URL parameters in custom AEM components to minimize DOM-based injection vectors. 7) Perform regular security testing, including penetration testing focused on client-side vulnerabilities, to detect similar issues proactively. 8) Consider isolating critical AEM instances behind VPNs or access controls to reduce exposure to external attackers.
