CVE-2026-75712 in Experience Manager as a Cloud Service
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 client-side vulnerability classified as a Document Object Model based Cross-Site Scripting flaw, which allows an attacker to inject and execute malicious JavaScript code within the context of a victim's web browser session. This type of vulnerability arises when an application processes user-supplied input without adequate validation or sanitization before writing it back into the DOM structure that is subsequently rendered by the browser engine. In this specific instance, the flaw resides in how Adobe Experience Manager handles certain inputs on its client-side interface, creating a pathway where untrusted data influences the execution environment of the web application directly through dynamic manipulation of page elements rather than server-side rendering errors.
The technical mechanism behind this exploitation involves an attacker crafting a malicious webpage or link that contains specially constructed JavaScript payloads designed to trigger the vulnerability when accessed by a user interacting with Adobe Experience Manager. When the victim visits the crafted resource, their browser parses the injected script and executes it within the security context of the trusted domain hosting Adobe Experience Manager. This effectively bypasses same-origin policy protections because the malicious code runs as if it were part of the legitimate application itself. The scope change noted in the vulnerability description indicates that the impact extends beyond simple data theft to potentially include full control over the user's session and interaction with the administrative interface, depending on the privileges held by the compromised account.
From an operational perspective, this vulnerability poses a significant risk because it relies on social engineering tactics requiring direct user interaction. An attacker must entice or trick a target into visiting the malicious webpage, often through phishing emails, compromised websites, or other deceptive means that leverage trust in familiar interfaces. Once executed, the malicious script can perform various harmful actions such as stealing session cookies and authentication tokens, performing unauthorized administrative actions on behalf of the user, redirecting the victim to further malware distribution sites, or defacing the application interface. The severity is amplified by the fact that Adobe Experience Manager is often used for managing critical digital assets and enterprise content where trust in the platform's integrity is paramount.
This vulnerability aligns with Common Weakness Enumeration identifier CWE-79, which describes Improper Neutralization of Input During Web Page Generation known as Cross-site Scripting. Specifically, it falls under DOM-based XSS rather than stored or reflected variants because the payload execution occurs entirely within the client-side environment without necessarily being sent to and echoed back by a server in the traditional sense. In terms of threat modeling and adversary behavior mapping according to MITRE ATT&CK framework, this exploitation technique corresponds to techniques involving Client-Side Scripting Injection and potentially Credential Access via Browser Session Hijacking if session tokens are exfiltrated. The attack vector is classified as Network with User Interaction required, indicating that while the vulnerability exists in a network-accessible application, successful exploitation depends on human behavior rather than automated remote code execution flaws.
Mitigation strategies for this issue primarily involve applying vendor-provided security patches and updates to Adobe Experience Manager instances immediately upon release. Administrators should ensure that all components of the platform are updated to versions where the input validation logic has been hardened against DOM manipulation attacks. Additionally, implementing Content Security Policy headers can help mitigate the impact by restricting the sources from which scripts can be loaded and executed, thereby preventing many types of injected code from running even if they reach the browser environment. Input sanitization at both the client-side JavaScript level and server-side validation layers should also be reviewed to ensure that any dynamic data written into DOM elements is properly encoded or escaped before rendering. Regular security audits focusing on cross-site scripting vulnerabilities are recommended to identify similar patterns in custom code integrated with Adobe Experience Manager, ensuring a defense-in-depth approach against this class of web application attacks.
