CVE-2025-46922 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 enables organizations to create, manage, and deliver personalized content across multiple channels. The platform serves as a central hub for digital asset management, content creation, and customer engagement workflows. This particular vulnerability affects the core content management capabilities of AEM, specifically targeting the form processing mechanisms that handle user input data. The stored XSS flaw exists within the form field validation and rendering components that process user-submitted data, creating a persistent security weakness that can be exploited across multiple user sessions.
The technical implementation of this vulnerability stems from inadequate input sanitization within the AEM form handling subsystem. When users submit data through web forms, the system fails to properly validate and escape special characters in the input fields before storing and rendering the content. This allows attackers to inject malicious JavaScript code directly into form fields that are later displayed to other users. The vulnerability specifically impacts the rendering pipeline where form data is processed and presented in web interfaces, creating a persistent XSS attack vector that remains active until the malicious content is manually removed from the database. The flaw operates at the application layer and requires no special privileges beyond normal user access to exploit effectively.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable sophisticated attack chains that compromise user sessions and data integrity. Low privilege attackers can leverage this weakness to perform session hijacking, steal sensitive cookies, redirect users to malicious domains, or execute malicious payloads that persist across multiple user interactions. The stored nature of the vulnerability means that once injected, malicious scripts will execute automatically for any user who views the affected content, potentially affecting hundreds or thousands of users depending on the scope of the compromised forms. This creates a significant risk for organizations relying on AEM for customer-facing applications where user data is frequently collected through forms.
Organizations should immediately implement input validation and output encoding measures to prevent malicious script injection into form fields. The recommended mitigation strategy includes implementing comprehensive content security policies that sanitize all user inputs before storage and properly escape all dynamic content during rendering. Security teams should conduct thorough audits of all form fields and user input mechanisms within the AEM environment to identify and remediate similar vulnerabilities. The vulnerability aligns with CWE-79 which categorizes cross-site scripting flaws as a fundamental web application security weakness, and corresponds to ATT&CK technique T1566 which covers social engineering through malicious content injection. Regular security assessments and vulnerability scanning should be implemented to detect similar weaknesses in the application's input handling mechanisms, while also ensuring that all AEM instances are updated to versions that address this specific vulnerability through proper code validation and sanitization routines.
