Summary
by MITRE • 07/14/2026
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 suffers from a dom-based cross-site scripting vulnerability that represents a critical security flaw in the platform's web application architecture. This vulnerability falls under the CWE-79 category, which specifically addresses cross-site scripting flaws where malicious scripts are injected into web pages viewed by other users. The dom-based nature of this vulnerability means that the attack vector operates entirely within the client-side javascript environment rather than through server-side input processing, making it particularly insidious as it leverages legitimate application functionality to execute malicious code.
The technical implementation of this flaw occurs when the application fails to properly sanitize or validate user-controllable data that is subsequently processed within the document object model. Attackers can craft malicious payloads that manipulate the browser's dom structure through parameters or url fragments that are not adequately filtered before being executed. This creates an environment where javascript code injected through manipulation of the dom can execute with the privileges and context of the authenticated user session, potentially leading to complete account compromise or data exfiltration.
The operational impact of this vulnerability extends beyond simple script execution as it provides attackers with the ability to perform actions that are typically restricted to legitimate users. When a victim visits a crafted webpage containing malicious javascript, the code executes within the victim's browser context and can access session cookies, perform api calls on behalf of the user, or redirect the user to malicious sites. The requirement for user interaction means that social engineering becomes a critical component of exploitation strategies, as attackers must convince users to visit compromised pages. This vulnerability effectively undermines the security model of the application by allowing attackers to exploit the trust relationship between the user and the web application.
Mitigation strategies should focus on implementing robust input validation and output encoding mechanisms throughout the application's dom manipulation processes. The solution requires comprehensive sanitization of all user-controllable data before it is processed or rendered within the browser environment, following the principle of least privilege for javascript execution contexts. Organizations should implement content security policies to restrict script execution, utilize secure coding practices that prevent direct dom manipulation with untrusted data, and conduct regular security testing including dynamic application security testing to identify potential injection points. The vulnerability also highlights the importance of proper session management and the need for multi-factor authentication to limit the impact of successful exploitation attempts, as outlined in the mitre att&ck framework's web application attack patterns.
