CVE-2025-47051 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 the AEM platform, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the maliciously crafted form field, the injected script executes in their browser context. This DOM-based XSS attack leverages the victim's browser to perform unauthorized actions such as session hijacking, credential theft, or unauthorized interactions with the web application. The vulnerability requires the attacker to have low privileges within the system and some level of user interaction (the victim must visit the compromised page). The CVSS v3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, and user interaction needed. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable module. No known exploits are reported in the wild yet, and no official patches have been linked at the time of publication. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation leading to XSS.

For European organizations using Adobe Experience Manager, this vulnerability poses a moderate risk. A successful exploit could lead to the execution of arbitrary scripts in the browsers of users interacting with the affected AEM instance, potentially compromising user sessions, stealing sensitive information, or enabling further attacks such as phishing or privilege escalation. Given that AEM is widely used by enterprises for content management and digital experience delivery, exploitation could impact customer-facing portals, intranet sites, or administrative consoles. This could result in reputational damage, regulatory non-compliance (especially under GDPR if personal data is compromised), and operational disruptions. The medium severity score reflects that while the vulnerability does not directly compromise server integrity or availability, the confidentiality and integrity of user data and sessions are at risk. European organizations with public-facing AEM deployments or those with internal users accessing vulnerable forms are particularly at risk. The lack of known exploits in the wild suggests a window for proactive mitigation before active exploitation occurs.

Organizations should immediately audit their Adobe Experience Manager installations to identify versions 6.5.22 and earlier. Until official patches are released, implement strict input validation and output encoding on all form fields to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Review and restrict user privileges to minimize the ability of low-privileged users to inject content. Monitor web server and application logs for suspicious input patterns or anomalous user behavior indicative of attempted XSS exploitation. Educate users to be cautious when interacting with forms and links on AEM-powered sites. Once Adobe releases a security update, prioritize patching to remediate the vulnerability. Additionally, consider deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. Conduct regular security assessments and penetration tests focusing on XSS vectors within AEM environments.
