CVE-2025-64614 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. This vulnerability arises from insufficient sanitization of user-supplied input in form fields, allowing an attacker with low privileges to inject malicious JavaScript code that is persistently stored on the server. When other users access the affected page containing the injected script, the malicious code executes in their browsers within the security context of the vulnerable web application. This can lead to unauthorized actions such as session hijacking, cookie theft, defacement, or redirection to malicious sites. The vulnerability has a CVSS 3.1 base score of 5.4, reflecting a medium severity level, with an attack vector of network (remote), low attack complexity, requiring privileges, and user interaction. The scope is changed, indicating that the vulnerability can affect resources beyond the initially vulnerable component. No patches are currently linked, and no known exploits have been reported in the wild, but the risk remains significant due to the widespread use of AEM in enterprise content management. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. Attackers exploiting this flaw could compromise confidentiality and integrity of user data but not availability. The vulnerability was reserved in early November 2025 and published in December 2025, indicating recent discovery.

For European organizations, the impact of CVE-2025-64614 can be substantial, particularly for those relying on Adobe Experience Manager for managing web content and digital experiences. Exploitation could lead to unauthorized disclosure of sensitive information such as session tokens, user credentials, or internal data, undermining confidentiality. Integrity could be compromised by altering web page content or injecting misleading information, potentially damaging organizational reputation and trust. Although availability is not directly affected, successful exploitation could facilitate further attacks or phishing campaigns targeting employees or customers. Given the medium severity and the requirement for some privileges and user interaction, the threat is moderate but should not be underestimated. Organizations in sectors such as finance, government, healthcare, and media, which often use AEM for critical web services, could face regulatory and compliance repercussions under GDPR if personal data is exposed. The risk is amplified in environments where multiple users access the vulnerable pages, increasing the attack surface.

To mitigate CVE-2025-64614, European organizations should implement a multi-layered approach: 1) Monitor Adobe's official channels for patches or security updates and apply them promptly once available. 2) Until patches are released, restrict access to vulnerable form fields to trusted users only and limit privileges to reduce exploitation risk. 3) Implement rigorous input validation and output encoding on all user-supplied data to prevent script injection. 4) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 5) Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including stored XSS. 6) Educate users and administrators about the risks of XSS and encourage cautious behavior when interacting with web content. 7) Utilize web application firewalls (WAFs) with updated rulesets to detect and block malicious payloads targeting known AEM vulnerabilities. 8) Review and harden AEM configurations to minimize exposure of vulnerable components and disable unnecessary features that accept user input.
