CVE-2025-46913 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields, allowing a high-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When other users visit the affected pages containing these vulnerable fields, the malicious script executes in their browsers within the context of the trusted domain. This can lead to unauthorized actions such as session hijacking, credential theft, or performing actions on behalf of the victim user. The vulnerability requires a high-privileged attacker to inject the payload, and user interaction is necessary for exploitation, as the victim must visit the compromised page. The CVSS 3.1 base score is 4.8 (medium severity), reflecting network attack vector, low attack complexity, required privileges, and user interaction. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. Given AEM's role as a content management system widely used by enterprises for managing web content and digital assets, exploitation could undermine the integrity and confidentiality of web applications and user data.

For European organizations using Adobe Experience Manager, this vulnerability poses a risk to the confidentiality and integrity of their web portals and digital services. Attackers with high privileges (such as administrators or content editors) could inject malicious scripts that compromise end-user sessions, steal sensitive information, or manipulate displayed content. This could lead to reputational damage, regulatory non-compliance (especially under GDPR due to potential data leakage), and operational disruption. Since AEM is often used by government agencies, financial institutions, and large enterprises across Europe, exploitation could affect critical public-facing services and internal portals. The requirement for high privileges limits the attack surface but insider threats or compromised admin accounts could facilitate exploitation. The need for user interaction (visiting the malicious page) means phishing or social engineering could be leveraged to maximize impact. Overall, the vulnerability could enable targeted attacks against European organizations relying on AEM for digital content delivery.

1. Immediately audit and restrict administrative and content editor privileges within Adobe Experience Manager to minimize the risk of malicious script injection. 2. Implement strict input validation and output encoding on all user-supplied data in form fields, especially those accessible to high-privileged users. 3. Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Monitor AEM logs for unusual content changes or injection attempts and establish alerting for suspicious activities. 5. Educate users and administrators about the risks of clicking on untrusted links or visiting unknown pages within the AEM environment. 6. Stay updated with Adobe security advisories and apply patches promptly once available. 7. Consider deploying web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting AEM. 8. Conduct regular security assessments and penetration testing focused on AEM instances to identify and remediate injection points proactively.
