CVE-2025-46906 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 provides robust features for creating, managing, and delivering digital content across multiple channels while maintaining security standards for sensitive business data. This particular vulnerability affects the core functionality of form handling within the application's user interface, specifically targeting the validation and sanitization processes for user inputs. The affected versions include all releases up to and including 6.5.22, indicating a widespread exposure across multiple product iterations. The vulnerability resides in the processing of user-submitted data within form fields that are subsequently displayed to other users, creating a persistent attack vector that can be exploited across multiple sessions and user interactions.
The technical flaw manifests as a stored cross-site scripting vulnerability that occurs when the application fails to properly sanitize user input before storing and rendering it within the web interface. This weakness allows an attacker to inject malicious javascript code into form fields that are then persisted in the application's database or storage mechanisms. When other users navigate to pages containing these vulnerable form fields, the malicious code executes within their browser context, potentially leading to unauthorized actions, data theft, or further exploitation. The vulnerability specifically affects form fields that are designed to accept user-generated content, where the application does not adequately filter or escape special characters that could be interpreted as executable code by web browsers. This represents a classic stored XSS flaw that aligns with CWE-79, which defines the weakness as the failure to sanitize user-controllable input before including it in output that is used as a web page.
The operational impact of this vulnerability extends beyond simple script execution, as it creates a persistent threat vector that can be leveraged for various malicious activities. Low privileged attackers can exploit this vulnerability to gain unauthorized access to user sessions, steal sensitive information, or manipulate content displayed to other users. The stored nature of the vulnerability means that the malicious payload remains active even after the initial injection, potentially affecting multiple users over extended periods. This type of vulnerability can be particularly damaging in enterprise environments where Adobe Experience Manager is used for customer-facing applications, internal portals, or any system handling sensitive user data. The attack surface includes any form field within the application that processes user input without proper sanitization, making it a significant concern for organizations that rely on the platform for business-critical applications. The vulnerability can be exploited through various means including web forms, comment sections, or any user-editable content areas that are subsequently rendered to other users.
Organizations should implement immediate mitigations including applying the latest security patches provided by Adobe, which typically address the input sanitization issues by implementing proper escaping and validation mechanisms. Network segmentation and monitoring should be enhanced to detect unusual script injection patterns in form submissions, while web application firewalls can provide additional layers of protection by filtering suspicious payloads. Input validation should be strengthened at multiple levels including client-side and server-side processing, with special attention to encoding user data before storage and rendering. Security teams should conduct comprehensive audits of all form fields and user-editable content areas to identify potential additional vulnerabilities, while implementing proper access controls to limit the impact of compromised accounts. The mitigation strategy should align with defensive techniques outlined in the attack phase of the kill chain, particularly focusing on preventing initial compromise and limiting the attack surface through proper input validation and output encoding. Organizations should also consider implementing automated security scanning tools that can detect stored XSS vulnerabilities in web applications, as these tools can help identify similar issues in custom implementations or third-party integrations that may be affected by similar security flaws.
