CVE-2025-47076 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 within AEM, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses a page containing the compromised form field, the malicious script executes in their browser context. This stored XSS vulnerability can lead to a range of attacks including session hijacking, credential theft, unauthorized actions on behalf of the user, and distribution of malware. The vulnerability has a CVSS 3.1 base score of 5.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low privileges, requires user interaction (victim must visit the malicious page), and impacts confidentiality and integrity with a scope change, but does not affect availability. No known exploits are currently reported in the wild, and no patches have been linked yet. Given AEM's role as a widely used enterprise content management system, this vulnerability poses a risk to organizations relying on it for web content delivery and digital asset management.

For European organizations, the impact of this vulnerability can be significant due to the widespread adoption of Adobe Experience Manager in sectors such as government, finance, healthcare, and large enterprises. Exploitation could lead to unauthorized access to sensitive information, compromise of user sessions, and potential defacement or manipulation of public-facing websites. This can damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR violations due to data exposure), and cause operational disruptions. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure users to maliciously crafted pages. The scope change in the CVSS vector indicates that the vulnerability could affect resources beyond the initially vulnerable component, potentially allowing attackers to escalate impact within the application context. Given the medium severity and the nature of stored XSS, the threat is moderate but should not be underestimated, especially in environments with high-value targets or sensitive data.

European organizations using Adobe Experience Manager should immediately audit their AEM instances to identify affected versions (6.5.22 and earlier). Until an official patch is released, organizations should implement strict input validation and output encoding on all user-supplied data within AEM forms to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly monitor web application logs for suspicious input patterns indicative of XSS attempts. Educate users about the risks of clicking unknown links to reduce the likelihood of successful social engineering. Additionally, isolate AEM instances from critical internal networks and enforce least privilege access controls to limit the potential damage of a successful exploit. Once Adobe releases a patch, prioritize timely deployment after testing in staging environments. Consider deploying Web Application Firewalls (WAFs) with updated rules to detect and block XSS payloads targeting AEM.
