CVE-2025-47033 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 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 injected script, the malicious code executes within their browser context. The vulnerability is classified as DOM-based XSS (CWE-79), meaning the attack payload manipulates the Document Object Model on the client side, potentially bypassing some traditional server-side filtering mechanisms. The CVSS v3.1 base score is 5.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), indicating the vulnerability affects components beyond the initially vulnerable component. The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N). No known exploits are currently reported in the wild, and no official patches or mitigation links have been published yet. Given AEM’s role as a content management system widely used by enterprises for web content delivery, exploitation could lead to session hijacking, defacement, or unauthorized actions performed in the context of authenticated users.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user trust. Exploitation could lead to theft of sensitive information such as session tokens, personal data, or corporate credentials, violating GDPR and other data protection regulations. The integrity of web content could be compromised, leading to misinformation or reputational damage. Since AEM is often used by large enterprises, government agencies, and public sector entities in Europe, successful attacks could disrupt critical communication channels or lead to targeted phishing campaigns leveraging the compromised web assets. The requirement for user interaction means social engineering could be used to increase attack success. Although the vulnerability does not affect availability directly, the broader impact on confidentiality and integrity could have cascading effects on business operations and regulatory compliance.

European organizations should prioritize the following mitigations: 1) Immediate review and sanitization of all user input fields in AEM forms, employing strict input validation and output encoding to prevent script injection. 2) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3) Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 4) Educate users and administrators about the risks of XSS and the importance of cautious interaction with web content. 5) Apply any forthcoming official patches from Adobe promptly once released. 6) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting AEM. 7) Conduct regular security assessments and penetration testing focused on client-side vulnerabilities. These steps go beyond generic advice by focusing on both immediate protective controls and long-term security hygiene tailored to AEM deployments.
