CVE-2025-47094 is a reflected Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises when an attacker crafts a malicious URL referencing a vulnerable page within AEM. When a victim clicks on this URL, the malicious JavaScript payload is executed in the context of the victim's browser session. Reflected XSS occurs because the application improperly sanitizes or encodes user-supplied input that is reflected immediately in the HTTP response. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 base score is 6.1, reflecting a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be performed remotely over the network without privileges and with low attack complexity, but requires user interaction (clicking a malicious link). The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact includes limited confidentiality and integrity loss, with no impact on availability. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability could allow attackers to steal session tokens, perform actions on behalf of the user, or conduct phishing attacks by injecting malicious scripts into trusted web pages served by AEM. Given that AEM is widely used for content management and digital experience delivery, exploitation could lead to significant reputational damage and potential data leakage.

For European organizations using Adobe Experience Manager, this vulnerability poses a risk primarily to web application security and user trust. Exploitation could lead to session hijacking, unauthorized actions performed in the victim's context, and exposure of sensitive information through malicious script execution. This is particularly critical for organizations handling personal data under GDPR, as any data leakage or unauthorized access could result in regulatory penalties. Additionally, compromised user sessions could facilitate further lateral attacks or phishing campaigns targeting employees or customers. The impact is heightened for sectors relying heavily on AEM for customer-facing portals, such as finance, healthcare, government, and e-commerce. The reflected XSS vulnerability could also be leveraged to bypass security controls or inject malware, increasing the attack surface. While the vulnerability does not affect system availability, the integrity and confidentiality risks are significant enough to warrant prompt attention, especially given the low complexity of exploitation and the lack of required privileges.

European organizations should implement the following specific mitigation measures: 1) Immediately review and apply any available security updates or patches from Adobe for AEM versions 6.5.22 and earlier. If patches are not yet available, consider temporary workarounds such as disabling or restricting access to vulnerable pages or components. 2) Implement rigorous input validation and output encoding on all user-supplied data reflected in web pages, using context-aware encoding libraries to prevent script injection. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4) Conduct thorough security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities in AEM deployments. 5) Educate users and administrators about the risks of clicking on suspicious links and encourage the use of multi-factor authentication to mitigate session hijacking risks. 6) Monitor web server and application logs for unusual activity or repeated attempts to exploit reflected XSS vectors. 7) Consider deploying Web Application Firewalls (WAFs) with rules specifically tuned to detect and block reflected XSS payloads targeting AEM. These measures, combined with prompt patching, will reduce the risk and potential impact of this vulnerability.
