CVE-2025-46934 in Experience Manager
Summary
by MITRE • 06/11/2025
Adobe Experience Manager versions 6.5.22 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.

Adobe Experience Manager represents a comprehensive digital experience platform that serves as a content management system for enterprise organizations. The platform facilitates the creation and management of web content while providing robust features for digital marketing automation and user experience optimization. Given its widespread adoption across corporate environments, vulnerabilities within AEM pose significant security risks to organizations relying on its functionality for their digital presence. The platform's architecture includes various form handling mechanisms that process user input through web interfaces, making it susceptible to injection attacks when proper validation and sanitization measures are absent.
The stored cross-site scripting vulnerability identified in CVE-2025-46934 specifically targets form field processing capabilities within AEM versions 6.5.22 and earlier. This flaw occurs when user-supplied data entered into form fields is not adequately sanitized before being stored in the system's database or content repository. The vulnerability manifests when malicious JavaScript code is submitted through these form fields and subsequently rendered without proper HTML encoding or output filtering. Attackers can exploit this weakness by crafting malicious payloads that, when stored in the application's content management system, execute automatically in the browsers of unsuspecting users who view the affected pages. This type of vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws in web applications.
The operational impact of this vulnerability extends beyond simple script execution as it provides attackers with a persistent vector for malicious activities. Low privilege attackers can leverage this weakness to establish a foothold within the application environment, potentially escalating their access through additional attacks or using the stored script as a delivery mechanism for more sophisticated exploits. The stored nature of the vulnerability means that the malicious payload remains active indefinitely until manually removed, creating a persistent threat that can affect multiple users over extended periods. This characteristic makes the vulnerability particularly dangerous in enterprise environments where content management systems are frequently accessed by numerous users, and where the affected pages may be publicly accessible or widely shared within organizational networks.
Organizations should immediately implement mitigations including comprehensive input validation and output encoding for all form fields within AEM installations. The platform's configuration should enforce strict sanitization of user inputs before storage, utilizing established libraries and frameworks designed to prevent XSS attacks. Security teams must conduct thorough audits of all form handling components to identify and remediate similar vulnerabilities across the application. Additionally, implementing content security policies and regular security scanning of the AEM environment can help detect and prevent exploitation attempts. The vulnerability demonstrates the critical importance of maintaining up-to-date security practices within content management systems, as outlined in the ATT&CK framework's web application exploitation techniques. Organizations should also consider implementing web application firewalls and monitoring systems to detect anomalous input patterns that may indicate attempted exploitation of similar vulnerabilities. Regular security training for developers and administrators regarding secure coding practices and proper input validation techniques remains essential for preventing such vulnerabilities from emerging in future releases.
