CVE-2025-64579 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. Stored XSS vulnerabilities occur when an attacker is able to inject malicious scripts into a web application’s persistent storage, such as form fields that save user input. In this case, a low-privileged attacker can exploit vulnerable form fields within AEM to insert JavaScript code that is then stored and later executed in the browsers of users who access the affected pages. The vulnerability leverages the CWE-79 classification, indicating improper neutralization of input leading to script injection. The CVSS 3.1 base score of 5.4 reflects that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), and low privileges (PR:L), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). This suggests that while the attacker can execute scripts that might steal session cookies or perform actions on behalf of users, the overall system availability remains unaffected. No patches or exploit code are currently publicly available, and no known exploits in the wild have been reported. However, given the widespread use of Adobe Experience Manager in enterprise content management and digital experience platforms, the vulnerability poses a credible risk if left unmitigated. Attackers could use this flaw to conduct phishing, session hijacking, or deliver malware through injected scripts. The vulnerability is particularly concerning for organizations that expose AEM-managed content to external users or have multiple internal users with varying privilege levels. The persistence of the injected script increases the risk of repeated exploitation until the vulnerability is remediated.

For European organizations, the impact of CVE-2025-64579 can be significant, especially for those relying on Adobe Experience Manager for managing websites, intranets, or digital customer experiences. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information such as authentication tokens or personal data, and potential manipulation of displayed content. This can damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and enable further attacks such as phishing or malware distribution. The medium severity score indicates a moderate risk, but the real-world impact depends on the deployment context, user base, and the sensitivity of the data handled by the affected AEM instance. Organizations with public-facing portals or those serving critical business functions are at higher risk. The requirement for user interaction means social engineering or targeted attacks may be necessary, but the low privilege needed to inject scripts lowers the barrier for attackers. The persistence of the stored XSS increases the window of exposure, potentially affecting multiple users over time. Given the strategic importance of digital services in Europe’s economy and public sector, exploitation could disrupt business operations or erode trust in digital platforms.

1. Apply official Adobe patches or updates as soon as they become available to address CVE-2025-64579. 2. Until patches are released, implement strict input validation and sanitization on all form fields within Adobe Experience Manager to prevent malicious script injection. 3. Employ output encoding techniques to ensure that user-supplied data is safely rendered in HTML contexts, neutralizing potential scripts. 4. Configure Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. 5. Conduct regular security audits and penetration testing focused on XSS vulnerabilities in AEM deployments. 6. Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content. 7. Monitor web application logs and user activity for signs of exploitation attempts or unusual behavior indicative of XSS attacks. 8. Consider implementing Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. 9. Limit the privileges of users who can submit content to minimize the risk posed by low-privileged attackers. 10. Review and harden AEM configurations to reduce attack surface, including disabling unnecessary features or components that handle user input.
