CVE-2025-47088 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, which pertains to 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, indicating that the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary (victim must visit the malicious page). The vulnerability impacts confidentiality and integrity by enabling script execution that could steal session tokens, perform actions on behalf of the user, or manipulate displayed content. Availability is not impacted. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability affects a widely used enterprise content management system, which is often deployed in web-facing environments, increasing the risk of exploitation if not mitigated promptly.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for managing web content and digital assets. Exploitation could lead to theft of sensitive user credentials, session hijacking, unauthorized actions within the web application, and potential spread of malware through injected scripts. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and operational disruptions. Organizations in sectors such as government, finance, healthcare, and media that use AEM to deliver public-facing or internal portals are particularly at risk. The medium severity score reflects that while the attack requires some user interaction and low privileges, the scope of impact can extend to multiple users if the malicious script is widely viewed. Given the persistent nature of stored XSS, the vulnerability could be exploited repeatedly until remediated.

European organizations should implement the following specific mitigations: 1) Immediately audit all AEM instances to identify and restrict access to vulnerable form fields, applying strict input validation and sanitization at the application level. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious script injection attempts targeting AEM forms. 3) Enforce Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers accessing AEM content. 4) Conduct user awareness training to reduce the risk of users clicking on suspicious links or content. 5) Monitor logs for unusual input patterns or repeated failed attempts to inject scripts. 6) Prepare for patch deployment by tracking Adobe’s security advisories and applying updates as soon as they are released. 7) Consider isolating or segmenting AEM environments to limit lateral movement in case of compromise. 8) Review and tighten user privileges within AEM to minimize the number of low-privileged users who can submit data to vulnerable fields.
