CVE-2025-47083 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 AEM, allowing a low-privileged attacker to inject malicious JavaScript code that is stored persistently on the server. When a victim user accesses a page containing the compromised form field, the malicious script executes in their browser context. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 base score is 5.4 (medium severity), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction (visiting the malicious page) is necessary. The vulnerability impacts confidentiality and integrity by potentially allowing theft of session tokens, user credentials, or manipulation of displayed content, but does not affect availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because AEM is widely used by enterprises for content management and digital experience delivery, making it a valuable target for attackers aiming to compromise user sessions or deface content.

For European organizations, the impact of this vulnerability can be considerable, especially for those relying on Adobe Experience Manager to manage public-facing websites, intranets, or customer portals. Exploitation could lead to theft of sensitive user data, including authentication tokens or personal information, potentially violating GDPR requirements for data protection and privacy. Additionally, attackers could manipulate website content, damaging brand reputation and customer trust. Since AEM is often integrated with other enterprise systems, a successful XSS attack could serve as a pivot point for further attacks or social engineering campaigns. The requirement for low privileges to exploit increases the risk, as even non-administrative users or external attackers who can submit form data might trigger the vulnerability. The need for user interaction (visiting the malicious page) means phishing or social engineering could be used to increase attack success. Overall, the vulnerability poses a medium risk to confidentiality and integrity of European organizations’ digital assets and user data.

European organizations using Adobe Experience Manager should take immediate steps to mitigate this vulnerability. First, monitor Adobe’s official security advisories and apply patches promptly once released. In the interim, implement strict input validation and output encoding on all user-supplied data in AEM forms to prevent script injection. Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. Conduct thorough code reviews and penetration testing focused on XSS vectors within AEM deployments. Limit privileges of users who can submit form data to reduce attack surface. Educate users and administrators about phishing risks to reduce likelihood of successful social engineering. Additionally, consider deploying Web Application Firewalls (WAFs) with rules targeting known XSS attack patterns to provide an additional layer of defense. Regularly audit logs for suspicious activities related to form submissions and page accesses. Finally, ensure incident response plans include procedures for handling XSS incidents to minimize damage.
