CVE-2025-64841 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM), a widely used enterprise content management system. The vulnerability exists in versions 6.5.23 and earlier, allowing attackers with low privileges to inject malicious JavaScript code into vulnerable form fields within the application. When legitimate users browse pages containing these fields, the injected scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The attack vector is network-based, with low complexity, but requires user interaction (visiting the compromised page). The vulnerability affects confidentiality and integrity but does not impact availability. The CVSS v3.1 score of 5.4 reflects these characteristics, categorizing it as medium severity. No public exploits or patches have been reported at the time of publication, indicating the need for vigilance and proactive mitigation. The vulnerability stems from insufficient input sanitization and output encoding in form fields, a common cause of stored XSS. Organizations using AEM to manage web content must be aware of this risk, as exploitation could compromise user trust and lead to data breaches. The vulnerability’s scope is limited to affected AEM versions, but given AEM’s popularity in Europe, the threat is significant. Monitoring for anomalous script injections and applying strict Content Security Policies (CSP) can help mitigate risk until official patches are released.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of user data and web sessions. Exploitation could allow attackers to steal session cookies, perform unauthorized actions, or deface websites, damaging organizational reputation and trust. Public sector entities, financial institutions, and large enterprises using Adobe Experience Manager for critical web portals are particularly vulnerable. The impact includes potential data breaches, regulatory non-compliance (e.g., GDPR), and operational disruptions due to compromised user accounts. Although availability is not directly affected, the indirect consequences of trust erosion and incident response costs can be substantial. The medium severity rating suggests moderate risk, but the widespread use of AEM in Europe amplifies potential impact. Organizations with high web traffic and sensitive user interactions are at greater risk. The absence of known exploits in the wild currently reduces immediate threat but does not eliminate future exploitation risk, especially if attackers develop automated tools targeting this vulnerability.

Organizations should implement the following specific measures: 1) Apply strict input validation and output encoding on all form fields within Adobe Experience Manager to prevent script injection. 2) Deploy and enforce robust Content Security Policies (CSP) to restrict execution of unauthorized scripts. 3) Monitor web application logs and user activity for signs of injected scripts or anomalous behavior. 4) Conduct regular security assessments and penetration testing focused on XSS vulnerabilities in AEM deployments. 5) Isolate critical web applications and limit privileges of users who can submit content to reduce attack surface. 6) Prepare to apply official Adobe patches immediately upon release and subscribe to Adobe security advisories. 7) Educate web content administrators and developers on secure coding practices related to XSS. 8) Use web application firewalls (WAF) with updated rules to detect and block XSS payloads targeting AEM. These steps go beyond generic advice by focusing on the specific context of AEM’s form fields and the nature of stored XSS attacks.
