CVE-2025-47015 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 interface. When a victim user accesses a page containing the injected malicious script, the script executes in their browser context. Stored XSS differs from reflected XSS in that the malicious payload is permanently stored on the target server, making it more persistent and potentially affecting multiple users over time. The vulnerability arises due to insufficient input validation or output encoding on form fields, enabling attackers to embed executable scripts. The CVSS 3.1 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), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). The scope change indicates that the vulnerability affects components beyond the initially vulnerable component, potentially increasing the impact. Although no known exploits are currently reported in the wild, the vulnerability poses a risk to organizations using affected AEM versions, especially since AEM is widely used for enterprise content management and web experience delivery. Attackers exploiting this vulnerability could steal session tokens, perform actions on behalf of users, or deliver further malware payloads, leading to data breaches or reputational damage.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of Adobe Experience Manager in government, financial, healthcare, and large enterprise sectors. Exploitation could lead to unauthorized access to sensitive information, session hijacking, and manipulation of web content, undermining user trust and compliance with data protection regulations such as GDPR. The persistent nature of stored XSS means multiple users could be affected over time, increasing the risk of data leakage or unauthorized actions. Additionally, compromised AEM instances could serve as a foothold for further attacks within the network. Given the medium severity and the requirement for user interaction, the threat is moderate but should not be underestimated, especially in environments with high-value targets or sensitive data. The confidentiality and integrity impacts could lead to regulatory penalties and financial losses if exploited.

To mitigate this vulnerability, European organizations should prioritize upgrading Adobe Experience Manager to a version where this vulnerability is patched once Adobe releases an official fix. In the interim, organizations should implement strict input validation and output encoding on all form fields to prevent script injection. Employing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts in browsers. Regularly auditing and sanitizing user-generated content stored in AEM can reduce the risk of stored malicious scripts. Additionally, organizations should enforce the principle of least privilege for users interacting with AEM, monitor logs for suspicious activities related to form submissions, and educate users about the risks of interacting with untrusted content. Deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM can provide an additional layer of defense. Finally, organizations should prepare incident response plans to quickly address any exploitation attempts.
