CVE-2026-75672 in Experience Manager as a Cloud Service
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 critical client-side security flaw classified as a Document Object Model-based Cross-Site Scripting vulnerability, which fundamentally alters the traditional scope of attack by shifting execution context to the end-user's browser environment rather than the server infrastructure. This specific type of vulnerability arises when an application processes untrusted data in a way that allows malicious scripts to be injected into the web page viewed by other users. In this instance, the flaw resides within how Adobe Experience Manager handles input parameters or dynamic content updates without adequate sanitization or encoding before rendering them into the DOM structure. The technical mechanism involves the manipulation of the browser's internal representation of the webpage, where attacker-controlled data is interpreted as executable code rather than inert text, thereby bypassing standard security controls that rely on server-side validation alone.
The operational impact of this vulnerability is significant because it enables an adversary to execute arbitrary JavaScript within the context of the victim's active session with Adobe Experience Manager. This execution occurs under the same origin policy constraints, meaning the malicious script has access to all cookies, local storage entries, and other sensitive data associated with the application domain for that specific user. Consequently, attackers can perform actions such as stealing authentication tokens, hijacking user sessions, performing unauthorized administrative operations on behalf of the victim, or redirecting users to phishing sites designed to harvest credentials. The requirement for user interaction, specifically visiting a crafted webpage, indicates that this is typically an active exploitation scenario where social engineering plays a pivotal role in delivering the malicious payload via links embedded in emails, chat messages, or other web content.
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. More specifically, it falls under the sub-category of DOM-based XSS where the vulnerability is triggered by client-side scripts rather than server-generated HTML. In terms of offensive security frameworks like MITRE ATT&CK, this technique maps to T1059 Command and Scripting Interpreter with a focus on JavaScript execution within web browsers, often utilized in subsequent phases such as Credential Access or Collection depending on the payload's intent. The shift in scope from server-side processing to client-side manipulation highlights the increasing complexity of modern web application security, where traditional perimeter defenses are insufficient against attacks that originate from and operate entirely within the user's browser environment.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. Adobe has released patches for affected versions which should be applied immediately by system administrators to close the specific code path responsible for the DOM manipulation flaw. Beyond patching, developers implementing or customizing Adobe Experience Manager components must adhere to strict input validation protocols, ensuring that all user-supplied data is properly encoded before being inserted into the DOM using methods like innerHTML or document.write. Utilizing Content Security Policy headers can also help mitigate the impact by restricting the sources from which scripts are allowed to load and execute, thereby reducing the effectiveness of injected payloads even if they manage to bypass initial validation checks. Regular security audits focusing on client-side code paths and automated static analysis tools configured to detect DOM-based XSS patterns are essential for maintaining a robust defense posture against this class of vulnerabilities.
