Summary
by MITRE • 09/09/2026
Adobe Experience Manager is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this issue by manipulating the DOM environment to execute malicious JavaScript within the context of the victim's browser. Exploitation of this issue requires user interaction in that a victim must visit a crafted webpage. Scope is changed.

Adobe Experience Manager contains a Document Object Model based Cross-Site Scripting vulnerability, commonly referred to as DOM-based XSS. This specific class of web security flaw differs from traditional reflected or stored XSS because the malicious script execution originates not from server-side input directly rendered into HTML, but rather from client-side JavaScript that processes untrusted data and writes it back into the Document Object Model in a way that allows code execution. In this instance, the vulnerability exists within Adobe Experience Manager such that an attacker can manipulate the DOM environment to inject or alter elements in a manner that triggers the execution of malicious JavaScript payloads. The root cause typically involves unsafe methods like innerHTML, outerHTML, or document.write being used with data derived from sources such as URL parameters, fragment identifiers, or other dynamic inputs without adequate sanitization or validation against script injection patterns.
The operational impact of this vulnerability is significant because it allows an attacker to execute arbitrary JavaScript code within the security context of the victim's browser. This means that any scripts executed have access to cookies, session tokens, local storage data, and potentially sensitive content displayed on the page associated with Adobe Experience Manager. An adversary could leverage this capability to steal user credentials, hijack active sessions, perform actions on behalf of the authenticated user, or redirect the victim to phishing sites designed to harvest additional information. The scope change noted in the vulnerability description indicates that the impact may extend beyond a single isolated context, potentially affecting broader application functionality or allowing lateral movement within the web application environment if other components are similarly vulnerable or share session contexts.
Exploitation of this flaw requires user interaction, specifically necessitating that a victim visits a crafted webpage controlled by the attacker. This page would contain links or embedded content designed to trigger the vulnerability when loaded in a browser running Adobe Experience Manager interfaces. While the requirement for user interaction provides some mitigation against fully automated remote attacks, it does not eliminate risk, particularly if social engineering techniques are employed to deceive users into clicking malicious links. The effectiveness of such an attack is often heightened by the fact that victims may trust the domain or interface they are interacting with, leading them to overlook subtle indicators of compromise in crafted URLs or embedded scripts.
To mitigate this vulnerability, developers and administrators should implement strict input validation and output encoding strategies for all data used in DOM manipulation operations. Utilizing context-aware escaping techniques ensures that special characters are rendered as harmless text rather than executable code. Furthermore, adopting Content Security Policy headers can significantly reduce the impact of successful XSS attacks by restricting the sources from which scripts can be loaded or executed. Regular security audits and static application security testing focused on client-side JavaScript logic are essential for identifying such flaws early in the development lifecycle. For end-users, maintaining up-to-date versions of Adobe Experience Manager is critical as patches often address these underlying code defects directly.
From a classification perspective, this vulnerability aligns with CWE-79, which covers Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. Specifically, the DOM-based nature places it within subcategories dealing with client-side script injection via dynamic content modification. In terms of adversary tactics and techniques, this exploit maps to MITRE ATT&CK technique T1059, Command and Scripting Interpreter, specifically through JavaScript execution in a browser context. Understanding these mappings helps security teams prioritize remediation efforts based on standardized frameworks that reflect both the technical nature of the flaw and its potential use in broader attack campaigns targeting enterprise web applications like Adobe Experience Manager.
