CVE-2025-47035 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, 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 input, the injected script executes within their browser context. This DOM-based XSS (CWE-79) can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized manipulation of the web application interface. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges but user interaction (victim must visit the malicious page). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. Given the nature of AEM as a widely used enterprise content management system, exploitation could impact web application integrity and user trust.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for critical web content delivery and customer engagement platforms. Successful exploitation could lead to theft of sensitive user data, including authentication tokens and personal information, potentially violating GDPR requirements. It could also enable attackers to perform actions on behalf of legitimate users, leading to reputational damage and loss of customer trust. Since AEM is often used by government, financial, and large enterprise sectors in Europe, the risk extends to critical infrastructure and services. The medium severity score reflects that while the vulnerability requires some user interaction and low privileges, the potential for data leakage and session compromise remains notable. Additionally, the changed scope means the impact could propagate beyond the initial vulnerable component, increasing the risk profile for interconnected systems.

European organizations should prioritize the following mitigation steps: 1) Immediately audit all AEM instances to identify versions 6.5.22 or earlier and plan for an upgrade to the latest patched version once available. 2) Implement strict input validation and output encoding on all user-supplied data, especially in form fields, to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Conduct regular security testing, including automated scanning and manual penetration testing focused on XSS vectors within AEM deployments. 5) Educate users and administrators about the risks of clicking on untrusted links or content within AEM-managed sites. 6) Monitor web server and application logs for unusual activity indicative of attempted exploitation. 7) Isolate critical AEM environments and restrict access to trusted users to minimize exposure. 8) Coordinate with Adobe support channels for timely patch information and advisories. These measures go beyond generic advice by focusing on proactive detection, layered defenses, and organizational awareness tailored to AEM environments.
