CVE-2025-64592 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. This vulnerability allows an attacker with low privileges to inject malicious JavaScript code into form fields that are stored and later rendered in web pages viewed by other users. When a victim accesses a page containing the injected script, the malicious code executes in their browser context, potentially allowing theft of session cookies, user credentials, or manipulation of the displayed content. The vulnerability arises from insufficient input sanitization and output encoding in the affected form fields. The CVSS 3.1 base score is 5.4, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, requiring privileges, and user interaction. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable module. No known exploits are currently in the wild, but the vulnerability poses a risk to confidentiality and integrity of user data. Adobe has not yet released a patch, so organizations must implement interim mitigations such as strict input validation and content security policies. Given AEM's widespread use in enterprise content management, exploitation could lead to targeted attacks against users of affected web applications.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive information such as session tokens or personal data, enabling account takeover or further exploitation. The integrity of web content could be compromised, damaging organizational reputation and trust. Since AEM is widely used by enterprises, government agencies, and media companies in Europe for managing digital content, exploitation could disrupt business operations and lead to compliance issues under GDPR if personal data is exposed. The requirement for low privileges and user interaction lowers the barrier for attackers, increasing the likelihood of targeted phishing or social engineering campaigns to trigger the vulnerability. Although availability impact is minimal, the confidentiality and integrity risks are significant, especially for organizations hosting customer-facing portals or intranet sites. The absence of known exploits currently provides a window for proactive mitigation, but the threat landscape could evolve rapidly.

Organizations should immediately audit their Adobe Experience Manager deployments to identify affected versions (6.5.23 and earlier). Until Adobe releases an official patch, implement strict input validation and sanitization on all form fields to prevent malicious script injection. Employ output encoding techniques to neutralize any injected scripts before rendering content to users. Deploy Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. Limit user privileges to the minimum necessary to reduce the risk of injection by low-privileged users. Monitor web application logs for suspicious input patterns or unusual user behavior indicative of exploitation attempts. Educate users about phishing risks that could lead to triggering the vulnerability. Plan for rapid deployment of Adobe patches once available and test updates in staging environments before production rollout. Consider web application firewalls (WAF) with rules targeting XSS payloads as an additional protective layer.
