CVE-2025-47013 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 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 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 vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction (visiting the page) is necessary. The scope is changed (S:C), indicating the vulnerability affects components beyond the vulnerable component itself. The impact affects confidentiality and integrity to a limited extent but does not affect availability. No known exploits are currently in the wild, and no patches have been linked yet. Stored XSS in AEM is particularly concerning because AEM is widely used by enterprises for content management and digital experience delivery, making it a valuable target for attackers to perform session hijacking, credential theft, or deliver further malware via trusted sites.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user trust. Exploitation could lead to unauthorized access to sensitive user data, session tokens, or internal systems if attackers leverage the XSS to escalate privileges or pivot within the network. Given AEM’s role in managing corporate websites, intranets, and customer portals, successful attacks could result in data breaches, reputational damage, and regulatory non-compliance under GDPR due to exposure of personal data. The requirement for low privileges to exploit increases the risk from insider threats or compromised accounts. Additionally, the cross-site scripting could be used to conduct phishing campaigns or deliver malware to users browsing affected sites. The medium CVSS score reflects moderate impact, but the real-world consequences could be more severe depending on the deployment context and the sensitivity of data handled by the affected AEM instance.

Organizations should prioritize the following actions: 1) Immediately audit all AEM instances to identify versions at or below 6.5.22 and plan for urgent upgrades once Adobe releases a patch. 2) Implement strict input validation and output encoding on all user-supplied data in AEM forms to prevent script injection, using context-aware encoding libraries. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce the impact of XSS. 4) Monitor web application logs and user activity for unusual behavior indicative of XSS exploitation attempts. 5) Educate developers and administrators on secure coding practices specific to AEM and XSS prevention. 6) Consider deploying Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting AEM. 7) Limit privileges of users who can submit data to vulnerable forms to reduce attack surface. 8) Regularly review and update incident response plans to include XSS attack scenarios relevant to AEM environments.
