Summary
by MITRE • 09/08/2026
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 client-side vulnerability classified as a Document Object Model based Cross-Site Scripting flaw, which allows for the execution of arbitrary JavaScript code within the security context of the vulnerable application. This type of vulnerability arises when an web application processes user-supplied input without proper validation or encoding before updating the DOM environment dynamically. In this specific instance, the underlying mechanism fails to adequately sanitize data that is subsequently written back into the page structure, creating a pathway for malicious scripts to be injected and executed by the victim's browser. The technical nature of this flaw aligns with CWE-79, which defines Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting.
The operational impact of exploiting this vulnerability is significant because it enables an attacker to bypass same-origin policy restrictions inherent in modern web browsers. By manipulating the DOM environment, a malicious actor can inject scripts that perform actions on behalf of the authenticated user. These actions may include stealing session cookies or authentication tokens, capturing keystrokes entered into forms, redirecting the victim to phishing sites, or defacing the application interface. Since Adobe Experience Manager is often used for managing digital content and customer experiences, compromising its integrity could lead to unauthorized modification of published assets or exposure of sensitive enterprise data stored within the platform's context.
Exploitation of this vulnerability requires active user interaction, specifically that a victim must visit a crafted webpage controlled by the attacker. This characteristic places the attack vector firmly in the realm of social engineering or drive-by attacks where trust is established through deceptive links or embedded content. The requirement for user initiation means that while automated remote exploitation without contact is not possible, the risk remains high due to the potential for targeted spear-phishing campaigns or compromised legitimate websites hosting malicious payloads. This scenario corresponds to ATT&CK technique T1059, Command and Scripting Interpreter, specifically focusing on browser-based execution vectors such as JavaScript within a web browser context.
To mitigate this vulnerability, developers must implement strict input validation and output encoding strategies for all data that is rendered into the DOM. Utilizing Content Security Policy headers can further restrict the sources from which scripts are allowed to execute, thereby limiting the impact of any successful injection attempt. Additionally, employing modern JavaScript frameworks with built-in escaping mechanisms or explicitly sanitizing inputs using libraries designed for this purpose can prevent malicious code execution. Regular security audits and static application security testing should be conducted to identify similar patterns in other parts of the Adobe Experience Manager interface where dynamic content updates occur based on user input.
