CVE-2025-47029 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, 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 malicious payload, the injected script executes in their browser context. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 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 performed remotely over the network with low attack complexity, requires low privileges, and user interaction (visiting the page) is necessary. The scope is changed (S:C), indicating the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality and integrity loss, as malicious scripts could steal session cookies, perform actions on behalf of users, or deface content, but does not affect availability. No known exploits are currently reported in the wild, and no patches are linked yet. This vulnerability is significant because AEM is widely used by enterprises for content management and digital experience delivery, often hosting customer-facing websites and portals. Exploitation could lead to session hijacking, unauthorized actions, or distribution of malware to site visitors.

For European organizations using Adobe Experience Manager, this vulnerability poses a risk to both internal users and external customers interacting with affected web applications. The stored XSS could enable attackers to steal authentication tokens, impersonate users, or manipulate displayed content, potentially leading to data breaches or reputational damage. Given AEM's role in managing digital content, exploitation could disrupt trust in online services or lead to compliance issues under GDPR if personal data is compromised. Attackers might also leverage this vulnerability to pivot into more critical systems if user credentials or session information are exposed. The medium severity score reflects moderate risk, but the widespread use of AEM in sectors such as government, finance, and retail across Europe elevates the potential impact. Additionally, the requirement for low privileges to inject malicious scripts means insider threats or compromised low-level accounts could exploit this vulnerability. The need for user interaction (visiting the malicious page) limits automated mass exploitation but targeted phishing or social engineering campaigns could increase risk.

European organizations should prioritize the following mitigation steps: 1) Immediately audit all AEM instances to identify versions at or below 6.5.22 and plan for prompt upgrade to patched versions once available. 2) Implement strict input validation and output encoding on all form fields, especially those accepting user-generated content, to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce impact of XSS attacks. 4) Conduct regular security testing, including automated scanning and manual penetration tests focusing on XSS vulnerabilities in AEM-managed sites. 5) Educate users and administrators about phishing risks and encourage cautious behavior when clicking links, as user interaction is required for exploitation. 6) Monitor web server and application logs for suspicious input patterns or unusual user activity indicative of attempted exploitation. 7) Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. 8) Review and restrict user privileges to minimize the ability of low-privileged users to inject malicious content. These measures, combined with timely patching, will significantly reduce the risk posed by this vulnerability.
