CVE-2025-47092 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 validation and output encoding in certain form fields within AEM, 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 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 the 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, 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’s scope is changed (S:C), indicating that exploitation could affect resources beyond the vulnerable component, possibly impacting other users or systems within the same domain. Stored XSS in a widely used enterprise content management system like AEM can be leveraged for targeted phishing, session hijacking, or delivering secondary payloads, making it a significant concern for organizations relying on AEM for web content delivery and management.

For European organizations using Adobe Experience Manager, this vulnerability poses a risk of client-side attacks that can compromise user data confidentiality and integrity. Attackers could exploit this flaw to steal authentication cookies, perform actions on behalf of users, or deface web content, undermining trust and potentially violating data protection regulations such as GDPR. Since AEM is often used by large enterprises, government agencies, and public sector bodies in Europe to manage critical web portals, exploitation could lead to reputational damage, regulatory fines, and operational disruptions. The requirement for low privileges to inject the malicious script means insider threats or compromised low-level accounts could be leveraged. The need for user interaction (visiting the affected page) means phishing or social engineering could be used to increase attack success. The changed scope indicates that multiple users or systems could be impacted, amplifying the potential damage within an organization’s web ecosystem.

European organizations should prioritize the following mitigations: 1) Apply official Adobe patches or updates as soon as they become available to remediate the vulnerability. 2) Implement strict input validation and output encoding on all user-supplied data in AEM forms to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 4) Conduct regular security audits and penetration testing focusing on web application inputs and stored content. 5) Limit privileges of users who can submit or manage content in AEM to reduce the risk of malicious input. 6) Educate users to recognize phishing attempts that might direct them to maliciously crafted pages. 7) Monitor web logs and user activity for unusual behavior indicative of exploitation attempts. 8) Consider deploying web application firewalls (WAFs) with rules targeting XSS payloads specific to AEM environments. These steps go beyond generic advice by focusing on both technical controls and organizational processes tailored to the nature of this stored XSS in AEM.
