CVE-2025-64569 is a DOM-based Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. The vulnerability arises from improper handling of user-controllable input within the Document Object Model (DOM) of web pages served by AEM, allowing an attacker to inject and execute arbitrary JavaScript code in the victim's browser context. This type of XSS is client-side and does not rely on server-side script injection but manipulates the DOM environment after the page loads. Exploitation requires a low-privileged attacker to craft a malicious URL or web page that, when visited or interacted with by a user, triggers the execution of the injected script. The attack vector is network-based (remote), with low attack complexity, requiring some privileges but necessitating user interaction (e.g., clicking a link). The vulnerability impacts confidentiality and integrity by potentially stealing session tokens, credentials, or performing actions on behalf of the user, but does not affect availability. The CVSS 3.1 base score is 5.4, reflecting medium severity with partial privileges and user interaction required. No patches were linked at the time of publication, and no known exploits have been reported in the wild. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation leading to XSS. Given AEM’s widespread use in enterprise content management and digital experience platforms, this vulnerability poses a risk to organizations relying on AEM for web content delivery.

For European organizations, the impact of CVE-2025-64569 can be significant, particularly for those using Adobe Experience Manager to manage public-facing websites or intranet portals. Successful exploitation can lead to theft of sensitive user information such as authentication tokens, personal data, or corporate credentials, enabling further attacks like session hijacking or privilege escalation. This can result in data breaches, reputational damage, and regulatory penalties under GDPR for failure to protect personal data. The vulnerability does not directly disrupt service availability but undermines user trust and data integrity. Organizations in sectors like finance, government, healthcare, and e-commerce, which rely heavily on secure web platforms, are at higher risk. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in phishing or social engineering campaigns. The medium severity rating indicates that while the threat is not critical, it remains a viable attack vector that can be leveraged in targeted attacks against European enterprises.

To mitigate CVE-2025-64569, European organizations should prioritize the following actions: 1) Monitor Adobe’s security advisories closely and apply official patches or updates for Adobe Experience Manager as soon as they become available. 2) Implement strict input validation and output encoding on all user-controllable inputs within AEM to prevent malicious script injection into the DOM. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Conduct regular security assessments and penetration testing focused on client-side vulnerabilities in web applications. 5) Educate end-users and administrators about the risks of interacting with suspicious links or content to reduce the likelihood of successful social engineering. 6) Use web application firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting AEM. 7) Review and minimize privileges assigned to users and services within AEM to reduce the impact of compromised accounts. These measures, combined, will reduce the attack surface and limit the potential for exploitation.
