CVE-2025-47084 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields within the AEM platform, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the malicious payload, the injected script executes in their browser context. This can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized modification of content, depending on the victim's privileges and the attacker's objectives. The vulnerability is classified under CWE-79, indicating a classic stored XSS flaw. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack can be launched remotely over the network (AV:N) with low attack complexity (AC:L), requiring low privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. Confidentiality and integrity impacts are low, while availability is not affected. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that organizations using affected AEM versions should prioritize mitigation and monitoring. Stored XSS in a widely used enterprise content management system like AEM poses significant risks, especially in environments where multiple users access the platform, as it can facilitate lateral movement and persistent compromise.

For European organizations, the impact of this vulnerability can be substantial, particularly for those relying on Adobe Experience Manager for web content management, digital marketing, and customer experience platforms. Exploitation could lead to unauthorized access to sensitive information, manipulation of web content, and potential compromise of user sessions, undermining trust and compliance with data protection regulations such as GDPR. The ability of a low-privileged attacker to inject persistent malicious scripts increases the risk of widespread impact across users and administrators interacting with the platform. This could result in reputational damage, legal liabilities, and operational disruptions. Given the medium severity, the threat is moderate but should not be underestimated, especially in sectors like finance, healthcare, government, and critical infrastructure where AEM is often deployed and where data sensitivity and regulatory scrutiny are high.

European organizations should implement the following specific measures: 1) Immediately audit and inventory all Adobe Experience Manager instances to identify affected versions (6.5.22 and earlier). 2) Apply vendor patches or updates as soon as they become available; if no patch is currently available, consider temporary mitigations such as disabling or restricting access to vulnerable form fields or modules. 3) Implement robust input validation and output encoding on all user-supplied data within AEM forms to prevent script injection. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5) Conduct regular security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities. 6) Monitor logs and user activity for signs of exploitation attempts or anomalous behavior. 7) Educate users and administrators about the risks of XSS and safe browsing practices. 8) Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. These steps go beyond generic advice by focusing on immediate risk reduction, proactive detection, and layered defense tailored to the specific vulnerability context.
