CVE-2025-64575 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. The vulnerability arises from insufficient sanitization of user input in certain form fields, allowing a low-privileged attacker to inject malicious JavaScript code that is stored persistently on the server. When a victim user accesses a page containing the injected script, the malicious code executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The vulnerability requires the attacker to have low-level privileges to submit data to the vulnerable form fields and requires user interaction to trigger the malicious script execution. The CVSS v3.1 base score of 5.4 reflects that the attack vector is network-based, with low attack complexity, requiring privileges and user interaction, and impacts confidentiality and integrity with no availability impact. The scope is changed (S:C) indicating that the vulnerability affects components beyond the vulnerable component itself, possibly impacting other parts of the system or user sessions. No patches were listed at the time of publication, and no known exploits in the wild have been reported. Given Adobe Experience Manager's widespread use in enterprise content management and web experience delivery, this vulnerability poses a moderate risk to organizations relying on AEM for public-facing or internal web portals.

For European organizations, the impact of CVE-2025-64575 can be significant in scenarios where Adobe Experience Manager is used to deliver web content to employees, partners, or customers. Successful exploitation could lead to unauthorized disclosure of sensitive information such as session cookies or personal data, enabling further attacks like account takeover or lateral movement within the network. The integrity of web content could be compromised, damaging organizational reputation and trust. Although availability is not directly impacted, the indirect consequences of data leakage or unauthorized actions could disrupt business operations. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, face heightened risks due to potential GDPR violations and associated penalties. The requirement for user interaction and low privileges lowers the barrier for exploitation, especially in environments with many users accessing AEM-managed portals. The absence of known exploits in the wild suggests a window of opportunity for proactive mitigation before widespread attacks occur.

1. Monitor Adobe’s official security advisories closely and apply patches or updates as soon as they become available to address CVE-2025-64575. 2. Implement strict input validation on all form fields within Adobe Experience Manager to reject or sanitize potentially malicious input before storage. 3. Employ robust output encoding techniques to ensure that any user-supplied data rendered in web pages is properly escaped, preventing script execution. 4. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM content. 5. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including stored XSS. 6. Educate users about the risks of clicking on suspicious links or interacting with untrusted content within corporate portals. 7. Enable logging and monitoring to detect unusual input patterns or script injection attempts in AEM logs. 8. Consider deploying Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting AEM. 9. Limit privileges for users who can submit content to only those necessary, reducing the attack surface. 10. Review and harden AEM configurations to minimize exposure of vulnerable components or forms.
