CVE-2025-47063 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. The 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 the affected page containing the maliciously crafted form field, the injected script executes in their browser context. This DOM-based XSS (CWE-79) can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized manipulation of the web application interface. The vulnerability has a CVSS 3.1 base score of 5.4, indicating a medium severity level. The vector details show that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requiring low privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. Confidentiality and integrity impacts are low, while availability is not affected. No known exploits are currently reported in the wild, and no patches have been linked yet. Given AEM's role as a content management system widely used for enterprise web content and digital asset management, exploitation could compromise the integrity of published content and potentially expose sensitive user data through malicious script execution in client browsers.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for public-facing websites, intranet portals, or digital marketing platforms. Successful exploitation could lead to the compromise of user sessions, theft of authentication tokens, or unauthorized actions performed on behalf of legitimate users. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations if personal data is exposed), and potential financial losses due to fraud or remediation costs. Since AEM is often used by government agencies, financial institutions, and large enterprises in Europe, the risk extends to critical sectors where trust and data integrity are paramount. The requirement for low privileges to exploit and the need for user interaction (e.g., a victim visiting a maliciously crafted page) means that social engineering or phishing campaigns could facilitate attacks. The medium severity rating suggests that while the vulnerability is not critical, it still poses a tangible risk that should be addressed promptly to prevent exploitation in targeted attacks.

Organizations should immediately review their Adobe Experience Manager deployments, specifically versions 6.5.22 and earlier, to identify if vulnerable form fields are present. Until an official patch is released, mitigation can include implementing strict input validation and output encoding on all user-supplied data within AEM forms to prevent script injection. Web Application Firewalls (WAFs) should be configured to detect and block common XSS payloads targeting AEM endpoints. Security teams should conduct thorough code reviews and penetration testing focusing on DOM-based XSS vectors. Additionally, user awareness training to recognize phishing attempts can reduce the risk of user interaction leading to exploitation. Monitoring web server and application logs for suspicious input patterns or anomalous user behavior can help detect attempted exploitation. Once Adobe releases a patch, organizations must prioritize timely deployment. Employing Content Security Policy (CSP) headers can also mitigate the impact of injected scripts by restricting the execution of unauthorized JavaScript.
