CVE-2025-64607 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. Stored XSS occurs when an attacker injects malicious scripts into web application input fields that are persistently stored on the server and later rendered in users' browsers without proper sanitization or encoding. In this case, a low-privileged attacker can exploit vulnerable form fields within AEM to embed malicious JavaScript code. When other users access the affected pages, the malicious script executes in their browsers, potentially allowing the attacker to steal session cookies, perform actions on behalf of the user, or manipulate displayed content. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity. The vector indicates network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), user interaction (UI:R), and a scope change (S:C) meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches were linked at the time of publication, suggesting organizations should monitor Adobe advisories closely. The vulnerability is classified under CWE-79, a common web application security flaw. Given AEM's widespread use in enterprise content management, this vulnerability poses a risk to organizations relying on it for digital content delivery and customer engagement.

For European organizations, the impact of CVE-2025-64607 can be significant, especially for those using Adobe Experience Manager to manage public-facing websites, intranets, or customer portals. Exploitation can lead to theft of sensitive information such as authentication tokens or personal data, enabling attackers to impersonate users or escalate privileges. This can result in data breaches, reputational damage, and regulatory non-compliance, particularly under GDPR requirements for data protection. The vulnerability does not directly affect system availability but compromises confidentiality and integrity, which can disrupt business operations and trust. Sectors such as finance, government, healthcare, and media, which often use AEM for digital content management, are particularly at risk. The requirement for user interaction means phishing or social engineering may be used to lure victims to vulnerable pages, increasing the attack surface. The medium severity score reflects a moderate but actionable risk that should be addressed promptly to prevent exploitation.

1. Monitor Adobe's official security advisories and apply patches or updates for Adobe Experience Manager as soon as they become available. 2. Implement strict input validation and output encoding on all form fields within AEM to prevent injection of malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including stored XSS. 5. Educate users and administrators about the risks of phishing and social engineering that could trigger malicious scripts. 6. Use web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. 7. Review and minimize the privileges of users who can submit content to vulnerable form fields to reduce the attacker's capabilities. 8. Implement security-focused development practices, including sanitizing user inputs and employing frameworks that automatically encode outputs. 9. Monitor logs and user activity for suspicious behavior that may indicate exploitation attempts. 10. Consider isolating or sandboxing content submitted through forms to limit the impact of any injected scripts.
