CVE-2025-64825 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. Stored XSS occurs when malicious scripts injected by an attacker are permanently stored on the target server, typically within form fields or content management inputs, and later executed in the browsers of users who access the affected pages. In this case, a low-privileged attacker can exploit vulnerable form fields to inject JavaScript code. When a victim visits the compromised page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with an attack vector of network (remote), low attack complexity, requiring low privileges but user interaction (victim must visit the infected page). The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable module, and the impact affects confidentiality and integrity but not availability. No patches or exploit code are currently publicly available, and no known active exploitation has been reported. Adobe Experience Manager is widely used by enterprises and governments for web content management, making this vulnerability relevant for organizations relying on AEM for public-facing or internal portals.

For European organizations, the impact of this stored XSS vulnerability can be significant depending on the deployment context of Adobe Experience Manager. Exploitation could lead to unauthorized disclosure of sensitive information, such as session tokens or personal data, through script execution in users’ browsers. This can facilitate account takeover, phishing, or lateral movement within internal networks if administrative users are targeted. The integrity of web content can be compromised, leading to defacement or misinformation. While availability is not directly affected, reputational damage and regulatory consequences under GDPR could be severe if personal data is exposed. Organizations with public-facing AEM portals or intranet sites accessible by employees or partners are particularly at risk. The medium severity score reflects the need for timely remediation but indicates that exploitation requires some user interaction and low privileges, limiting the ease of attack.

1. Apply official Adobe patches or updates as soon as they become available to address CVE-2025-64825. 2. Implement strict input validation and sanitization on all form fields within AEM to prevent injection of malicious scripts. 3. Use context-aware output encoding (e.g., HTML entity encoding) to neutralize any injected scripts before rendering content in browsers. 4. Restrict access to form fields and content editing interfaces to trusted and authenticated users only, minimizing the attack surface. 5. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 6. Monitor web application logs and user activity for unusual input patterns or suspicious behavior indicative of exploitation attempts. 7. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including XSS. 8. Educate users and administrators about the risks of XSS and safe browsing practices to reduce the likelihood of successful exploitation.
