CVE-2025-47007 is a stored Cross-Site Scripting (XSS) vulnerability affecting 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 environment. When a victim user subsequently visits the affected page containing the injected script, the malicious code executes in their browser context. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.4 (medium severity), with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges, and user interaction (victim must visit the malicious page). The scope is changed, meaning the vulnerability can affect components beyond the initially vulnerable module. The impact affects confidentiality and integrity but not availability, as the malicious script could steal sensitive data or perform unauthorized actions on behalf of the victim user. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability arises from insufficient input validation and output encoding in form fields, allowing persistent script injection that is stored on the server and delivered to other users. This can lead to session hijacking, credential theft, or unauthorized actions within the context of the victim's session in AEM-based applications.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user data confidentiality. A successful exploit could allow attackers to compromise user sessions, steal authentication tokens, or manipulate content displayed to users, potentially leading to data breaches or unauthorized administrative actions. Given AEM's widespread use in enterprise content management and digital experience platforms across Europe, especially in sectors like government, finance, and media, exploitation could disrupt business operations and damage reputation. The vulnerability's requirement for user interaction means phishing or social engineering could be used to lure victims to malicious pages. Additionally, the scope change indicates that the impact could extend beyond a single component, potentially affecting integrated services or modules within AEM deployments. Although no active exploits are known, the medium severity score and ease of injection by low-privileged attackers make timely remediation critical to prevent targeted attacks against European entities.

European organizations should immediately audit their Adobe Experience Manager deployments to identify affected versions (6.5.22 and earlier). Until an official patch is released, implement strict input validation and output encoding on all form fields to prevent script injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting AEM form inputs. Enable Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Conduct user awareness training to reduce the risk of social engineering attacks that could lead users to malicious pages. Regularly monitor logs for unusual input patterns or user behavior indicative of exploitation attempts. Once Adobe releases a patch, prioritize its deployment in all environments. Additionally, consider isolating AEM instances and limiting user privileges to reduce the attack surface. Implement multi-factor authentication for administrative access to mitigate the impact of session hijacking.
