CVE-2025-47030 is a stored Cross-Site Scripting (XSS) vulnerability identified in 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 the affected page containing the maliciously crafted form field, the injected script executes within their browser context. This can lead to unauthorized actions such as session hijacking, credential theft, or performing actions on behalf of the victim user. The vulnerability has a CVSS 3.1 base score of 5.4, indicating a medium severity level. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) and low privileges (PR:L), but user interaction is necessary (UI:R) as the victim must visit the compromised page. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity to a limited extent (C:L/I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. Stored XSS vulnerabilities in web content management systems like AEM are particularly dangerous because they can affect multiple users and persist until remediated. Given AEM’s widespread use in enterprise content management, this vulnerability could be leveraged to compromise user sessions, steal sensitive information, or facilitate further attacks within the affected organization’s web environment.

For European organizations using Adobe Experience Manager, this vulnerability poses a risk to the confidentiality and integrity of user data and sessions. Attackers exploiting this flaw could execute malicious scripts in the browsers of employees, customers, or partners accessing affected AEM-powered websites or portals. This could lead to credential theft, unauthorized access to sensitive information, or manipulation of web content. Since AEM is often used by large enterprises, government agencies, and public sector organizations in Europe to manage digital experiences and internal portals, exploitation could disrupt business operations and erode trust. The medium severity rating reflects that while the vulnerability does not directly impact system availability, the potential for data leakage and session compromise can have significant reputational and operational consequences. Additionally, the requirement for user interaction means phishing or social engineering may be used to lure victims to the malicious content, increasing the risk of targeted attacks against high-value users within European organizations.

European organizations should prioritize the following mitigation steps: 1) Immediately review and apply any official Adobe patches or security updates once released for AEM versions 6.5.22 and earlier. 2) Implement strict input validation and output encoding on all user-supplied data within AEM forms to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Conduct thorough security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities in all AEM-managed web applications. 5) Educate users and administrators about the risks of clicking on suspicious links or content that may exploit this vulnerability. 6) Monitor web server and application logs for unusual activity or attempts to inject scripts. 7) Consider deploying Web Application Firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting AEM. 8) Limit privileges of users who can submit content to AEM forms to reduce the attack surface. These targeted measures go beyond generic advice by focusing on the specific context of AEM’s architecture and typical deployment scenarios in European enterprises.
