CVE-2025-47079 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability allows a low-privileged attacker to inject malicious JavaScript code into vulnerable form fields within the AEM interface. When a victim subsequently accesses the affected page containing the injected script, the malicious code executes in their browser context. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is permanently stored on the server and served to any user who visits the compromised page, increasing the attack surface and potential impact. The vulnerability requires low privileges to exploit but does require user interaction, as the victim must visit the infected page for the script to execute. The CVSS 3.1 score of 5.4 (medium severity) reflects that the attack vector is network-based with low attack complexity, requiring privileges but user interaction, and impacts confidentiality and integrity with no impact on availability. The scope is changed (S:C), indicating the vulnerability can affect resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability is categorized under CWE-79, which is a common and well-understood web application security weakness involving improper neutralization of input leading to script injection.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to the confidentiality and integrity of their web applications and user data. A successful exploit could lead to session hijacking, credential theft, unauthorized actions performed on behalf of users, or distribution of malware via the compromised web interface. Given that AEM is widely used by enterprises, government agencies, and media companies across Europe for content management and digital experience delivery, exploitation could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and financial losses. The stored nature of the XSS means multiple users can be affected once the malicious script is injected, amplifying the potential damage. Additionally, attackers with low privileges can leverage this vulnerability to escalate their access or pivot to other attacks within the affected environment. The requirement for user interaction (visiting the infected page) means social engineering or phishing could be used to increase exploitation success.

European organizations should implement the following specific mitigations: 1) Immediately audit all AEM instances to identify and isolate vulnerable versions (6.5.22 and earlier). 2) Apply the official Adobe patches or security updates as soon as they become available; if patches are not yet released, consider temporary workarounds such as disabling or restricting access to vulnerable form fields or pages. 3) Implement strict input validation and output encoding on all user-supplied data within AEM forms to prevent script injection. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5) Conduct user awareness training to reduce the risk of users visiting maliciously crafted pages. 6) Monitor web server and application logs for unusual input patterns or script injections. 7) Use web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. 8) Regularly review and update security configurations and conduct penetration testing focused on XSS vulnerabilities. These steps go beyond generic advice by focusing on immediate containment, layered defenses, and proactive detection tailored to AEM environments.
