CVE-2026-110075 in Experience Manager
Summary
by MITRE • 10/13/2026
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, commonly referred to as DOM XSS. This type of vulnerability arises when an application processes data from the user's environment in an unsafe manner and writes that data into the HTML document without proper validation or encoding. In this specific instance within Adobe Experience Manager, the underlying code fails to adequately sanitize input before it is utilized by JavaScript functions that manipulate the page structure. Consequently, if a victim interacts with a maliciously crafted webpage designed to trigger this flaw, an attacker can inject arbitrary scripts into the DOM tree. These scripts are then executed in the context of the vulnerable application's domain, effectively bypassing same-origin policy protections and allowing the attacker to access sensitive data or perform actions on behalf of the user.
The operational impact of exploiting a DOM-based XSS vulnerability is significant because it allows for session hijacking, credential theft, defacement, or redirection to malicious sites without requiring server-side compromise. Since the attack vector relies entirely on client-side manipulation, traditional web application firewalls that inspect HTTP request payloads may fail to detect this threat unless they are specifically configured to monitor DOM activity and script execution contexts. The requirement for user interaction means that social engineering tactics such as phishing emails or deceptive links are necessary to initiate the exploit chain. Once triggered, the malicious JavaScript runs with the same privileges as legitimate scripts from Adobe Experience Manager, potentially granting access to administrative functions if an administrator is targeted, thereby escalating the risk from a simple data leak to full system compromise within the content management environment.
From a classification perspective, this vulnerability aligns closely with CWE-79, which covers Improper Neutralization of Input During Web Page Generation known as Cross-site Scripting. More specifically, it falls under the sub-category of DOM-based XSS where the source is often an untrusted JavaScript variable or property and the sink is a function that writes to the document such as innerHTML or document.write. In terms of offensive security frameworks, this exploit maps directly to MITRE ATT&CK technique T1059 which encompasses Command and Scripting Interpreter execution via browser-based mechanisms like JavaScript. Understanding these mappings helps in prioritizing remediation efforts based on established industry standards for web application security testing and mitigation strategies.
To mitigate this vulnerability, developers must implement strict input validation and output encoding practices within the client-side codebase of Adobe Experience Manager. This involves ensuring that any data derived from user-controlled sources is properly encoded before being rendered into HTML elements or executed as JavaScript. Utilizing Content Security Policy headers can also provide a layer of defense by restricting the origins from which scripts can be loaded, thereby limiting the impact if an injection does occur. Additionally, Adobe has released patches and updates to address this specific flaw in their software releases. Administrators should immediately apply these security updates to ensure that the underlying code handles DOM manipulation securely. Regular security audits focusing on client-side scripting practices and automated static analysis tools configured for DOM XSS detection are recommended to prevent similar issues from being introduced during future development cycles or customizations of the platform.
