CVE-2025-64619 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 input is saved on the server and later rendered in users’ browsers without proper sanitization or encoding. In this case, a low-privileged attacker can inject malicious JavaScript code into vulnerable form fields within AEM. When legitimate users access pages containing these fields, the injected script executes in their browsers, potentially allowing the attacker to steal session cookies, perform actions on behalf of the user, or redirect users to malicious sites. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity. The attack vector is network-based, with low attack complexity, requiring privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. No known exploits have been reported in the wild, but the vulnerability is publicly disclosed and should be addressed promptly. Adobe Experience Manager is widely used by enterprises for managing web content and digital experiences, making this vulnerability relevant for organizations relying on AEM for public-facing or internal portals. The lack of a patch link suggests that a fix may be pending or not yet publicly released, emphasizing the need for interim mitigations.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of sensitive information such as session tokens or personal data, undermining confidentiality. Attackers could also manipulate user sessions, leading to integrity violations by performing unauthorized actions within the affected application. Although availability is not directly impacted, successful exploitation could facilitate further attacks or phishing campaigns. Organizations using AEM for customer-facing websites or intranets are at particular risk, as attackers could target employees or customers. This could damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR breaches), and result in financial losses. The medium CVSS score reflects moderate risk, but the widespread use of AEM in Europe and the potential for chained attacks elevate the threat significance. The requirement for user interaction and some privileges limits exploitation ease but does not eliminate risk, especially in environments with many users and complex workflows.

1. Monitor Adobe’s official channels for patches addressing CVE-2025-64619 and apply updates promptly once available. 2. Implement strict server-side input validation and output encoding on all form fields 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 audits and penetration testing focused on web application vulnerabilities, including XSS. 5. Educate users and administrators about phishing and social engineering risks associated with XSS exploitation. 6. Use web application firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting AEM. 7. Limit privileges for users who can submit content to the minimum necessary to reduce the attack surface. 8. Review and harden AEM configurations to disable or restrict vulnerable components or features until patches are applied.
