CVE-2025-46891 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 cornerstone for enterprise content management and digital marketing operations. This platform enables organizations to create, manage, and deliver digital experiences across multiple channels while providing robust content authoring capabilities. The vulnerability under analysis affects versions 6.5.22 and earlier, which have been widely deployed across enterprise environments, making this issue particularly concerning given the platform's critical role in digital infrastructure. The affected system operates as a web-based content management solution that processes user inputs through various form fields and content editing interfaces, creating multiple potential attack vectors for malicious actors seeking to exploit weaknesses in input validation and output encoding mechanisms.
The stored cross-site scripting vulnerability stems from insufficient validation of user-supplied data within form fields and content management interfaces. Attackers with low privileged access can inject malicious javascript code into vulnerable input fields that are subsequently stored within the system's database or content repository. This stored payload remains persistent within the application environment and executes whenever users browse to pages containing the compromised form fields. The technical flaw manifests in the platform's failure to properly sanitize and encode user input before rendering it in web responses, creating a direct pathway for malicious scripts to be executed in the context of authenticated user sessions. This vulnerability specifically impacts the content rendering pipeline where user-generated content flows through the system without adequate security controls to prevent script injection attacks.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to potentially escalate privileges, steal session cookies, perform actions on behalf of users, and access sensitive content or system resources. Low privilege attackers who can submit content through forms or editing interfaces gain the ability to compromise other users who view the malicious content, creating a significant risk for enterprise environments where multiple users interact with shared content management systems. The persistent nature of stored XSS means that the malicious payload remains active until manually removed, allowing attackers to maintain access and continue exploiting the vulnerability over extended periods. This threat is particularly dangerous in enterprise settings where Adobe Experience Manager serves as a central hub for digital content and where users may have varying levels of access and privilege within the system.
Security mitigations for this vulnerability should focus on implementing comprehensive input validation and output encoding controls throughout the application's content processing pipeline. Organizations must ensure that all user-supplied data undergoes strict sanitization before being stored or rendered in web responses, with particular attention to form fields, content editors, and any user-contributed content areas. The implementation of content security policies and proper encoding mechanisms for HTML, javascript, and other potentially dangerous content types forms a critical defense layer. Regular security updates and patches should be deployed immediately upon availability, with organizations maintaining strict version control and vulnerability management processes. System administrators should also implement monitoring and logging controls to detect unusual content submission patterns and potential exploitation attempts, while security teams should conduct regular penetration testing and code reviews to identify similar vulnerabilities within the application's architecture. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and represents a clear violation of ATT&CK technique T1566 related to credential access through malicious content delivery.
