CVE-2025-47011 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 vulnerabilities are particularly dangerous because the malicious payload is saved on the server and served to multiple users, increasing the attack surface and potential impact. The vulnerability requires low privileges to exploit but does require user interaction, as the victim must visit the compromised page for the script to execute. The CVSS 3.1 base score is 5.4 (medium severity), reflecting the network attack vector, low attack complexity, low privileges required, and user interaction needed. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable module, potentially impacting confidentiality and integrity but not availability. The vulnerability could be leveraged to steal session tokens, perform actions on behalf of users, or conduct phishing attacks within the trusted domain of the AEM instance. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that organizations should prioritize monitoring and mitigation efforts proactively.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to the confidentiality and integrity of their web applications and user data. A successful exploit could lead to unauthorized access to sensitive information, session hijacking, and manipulation of content or user interactions within the affected AEM portals. Given that AEM is widely used by enterprises, government agencies, and media companies across Europe for content management and digital experience delivery, exploitation could disrupt business operations and damage reputation. The stored nature of the XSS means multiple users could be affected once malicious scripts are injected, amplifying the impact. Additionally, attackers could use this vulnerability as a foothold for further attacks within the corporate network or to spread malware. The medium severity rating suggests that while the vulnerability is not critical, it still requires timely attention to prevent exploitation, especially in environments with sensitive data or high-value targets.

Organizations should implement the following specific mitigations: 1) Immediately review and restrict user permissions within AEM to minimize the number of users who can submit data to vulnerable form fields. 2) Employ rigorous input validation and output encoding on all user-supplied data in AEM forms to prevent script injection. 3) Monitor web application logs and user activity for unusual input patterns or repeated form submissions that could indicate exploitation attempts. 4) Deploy Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers accessing AEM content. 5) Isolate AEM instances from critical internal networks to reduce lateral movement risk if exploitation occurs. 6) Stay alert for official Adobe patches or security advisories and apply updates promptly once available. 7) Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including stored XSS, to identify and remediate weaknesses proactively.
