CVE-2025-47082 is a stored Cross-Site Scripting (XSS) vulnerability identified in 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 platform. When a victim accesses a page containing the compromised form field, the malicious script executes in their browser context. Stored XSS differs from reflected XSS in that the malicious payload is permanently stored on the server, making it more persistent and potentially affecting multiple users over time. The vulnerability arises due to insufficient input validation or output encoding on user-supplied data in form fields, enabling script injection. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based (AV:N), requires low privileges (PR:L), and user interaction (UI:R) is necessary for exploitation. The scope is changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable component, potentially impacting other parts of the system. The impact affects confidentiality and integrity (C:L, I:L) but not availability (A:N). There are no known exploits in the wild at the time of publication, and no patch links have been provided yet. Given the widespread use of Adobe Experience Manager in enterprise content management and digital experience delivery, this vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed in the context of affected users.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for managing customer-facing websites, intranets, or digital services. Exploitation could lead to unauthorized access to sensitive information, such as user credentials or personal data, violating GDPR requirements and potentially resulting in regulatory fines. The integrity of web content could be compromised, damaging brand reputation and user trust. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure victims to vulnerable pages. The persistence of stored XSS increases the risk of widespread impact across multiple users and sessions. Organizations in sectors such as finance, healthcare, government, and e-commerce, which often use AEM for digital content management, may face increased risk of data breaches or service manipulation. Additionally, the cross-site scripting could be leveraged to deliver further malware or conduct lateral movement within internal networks if internal users are targeted.

European organizations should prioritize the following mitigation steps: 1) Immediately assess the version of Adobe Experience Manager in use and plan for an upgrade to a patched version once available. 2) In the interim, implement strict input validation and output encoding on all form fields to neutralize malicious scripts. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Conduct thorough code reviews and security testing focusing on user input handling in AEM components. 5) Educate users and administrators about the risks of phishing and social engineering that could facilitate exploitation. 6) Monitor web application logs for unusual input patterns or script injection attempts. 7) Use web application firewalls (WAFs) with rules targeting XSS payloads to provide an additional layer of defense. 8) Limit user privileges to the minimum necessary to reduce the attack surface. 9) Prepare incident response plans to quickly address any exploitation attempts. These steps go beyond generic advice by focusing on immediate protective measures and organizational readiness until official patches are released.
