CVE-2025-47070 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability allows a low-privileged attacker to inject malicious JavaScript code into vulnerable form fields within the AEM environment. When a victim user accesses a page containing the compromised form field, the malicious script executes in their browser context. The vulnerability is classified as CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based (AV:N), requires low privileges (PR:L), and user interaction (UI:R) is necessary for exploitation. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no official patches have been linked yet. Stored XSS vulnerabilities in AEM are particularly concerning because AEM is widely used by enterprises for content management and digital experience delivery, often hosting sensitive business and customer data. Successful exploitation could lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim user, potentially compromising organizational security and user trust.

For European organizations, the impact of this vulnerability can be significant given the widespread adoption of Adobe Experience Manager in sectors such as government, finance, retail, and media. Exploitation could lead to unauthorized access to sensitive information, manipulation of web content, and potential spread of malware through trusted websites. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and financial losses. The requirement for user interaction means phishing or social engineering could be used to lure victims to vulnerable pages. Since AEM often serves as a customer-facing platform, attacks could affect end-users, amplifying the impact. Additionally, the scope change in the vulnerability suggests that exploitation might affect multiple components or users beyond the initially targeted form, increasing the risk of broader compromise within an organization’s digital ecosystem.

European organizations should prioritize the following specific mitigation steps: 1) Immediately audit all AEM instances to identify versions 6.5.22 and earlier and plan for an upgrade to the latest patched version once available from Adobe. 2) Implement strict input validation and output encoding on all form fields and user-generated content within AEM to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM content. 4) Conduct regular security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities in AEM environments. 5) Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content hosted on AEM platforms. 6) Monitor web server and application logs for unusual activity indicative of attempted XSS exploitation. 7) Use web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting AEM. 8) Segregate AEM environments and restrict administrative access to minimize the impact of potential exploitation.
