CVE-2025-47016 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 a page containing the compromised form field, the injected script executes in their browser context. This can lead to session hijacking, credential theft, unauthorized actions performed on behalf of the user, or delivery of further malware payloads. The vulnerability requires the attacker to have at least low privileges to submit malicious input, and user interaction is necessary for exploitation since the victim must visit the affected page. The CVSS v3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, but requiring user interaction and resulting in limited confidentiality and integrity impact without availability impact. The vulnerability has been publicly disclosed but no known exploits are currently observed in the wild. No official patches or mitigation links have been provided yet, indicating that organizations must rely on interim protective measures until Adobe releases a fix.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user trust. A successful exploit could allow attackers to steal session cookies or credentials of users, potentially including administrators or privileged users, leading to unauthorized access to sensitive content or administrative functions. This can result in data breaches, defacement of websites, or further compromise of internal systems. Since AEM is widely used by enterprises and public sector organizations across Europe for content management and digital experience delivery, the impact could extend to critical infrastructure, government portals, and commercial websites. The persistent nature of stored XSS increases the risk of widespread impact on site visitors and internal users. Additionally, the vulnerability could be leveraged in targeted phishing or social engineering campaigns to escalate access or spread malware within European networks.

European organizations should immediately audit their AEM deployments to identify any exposed form fields susceptible to script injection. Until an official patch is released by Adobe, organizations should implement the following measures: 1) Apply strict input validation and output encoding on all user-supplied data in AEM forms, leveraging web application firewalls (WAFs) to detect and block malicious payloads targeting known vulnerable fields. 2) Restrict low-privileged user access to form submission features where possible, minimizing the attack surface. 3) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 4) Conduct thorough user awareness training to reduce the risk of users interacting with suspicious content. 5) Monitor web server and application logs for unusual input patterns or error messages indicative of attempted exploitation. 6) Prepare for rapid deployment of Adobe patches once available and test updates in staging environments before production rollout. These targeted steps go beyond generic advice by focusing on the specific vulnerability context and the operational environment of AEM in European organizations.
