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 Cross-Site Scripting vulnerability classified under CWE-79, which allows an attacker to inject and execute malicious JavaScript code within the context of the victim's browser. This specific flaw stems from insufficient validation or sanitization of user-supplied input that is subsequently written into the Document Object Model without proper encoding. By manipulating the DOM environment through crafted web content, such as specially designed URLs or forms embedded in a third-party site, an adversary can bypass standard security controls and inject scripts that run with the same privileges as legitimate application code. This type of vulnerability is categorized under MITRE ATT&CK technique T1059.007, which covers JavaScript execution on client-side targets.
The operational impact of this vulnerability is significant because it enables session hijacking, credential theft, and defacement of the user interface. Since the malicious script executes in the context of the trusted Adobe Experience Manager domain, attackers can access sensitive cookies, local storage data, or other authentication tokens that are not marked as HTTP-only. This allows for unauthorized access to administrative functions or personal user data without requiring direct server-side exploitation. The requirement for user interaction means that social engineering tactics, such as phishing emails containing links to the crafted webpage, are often necessary to trigger the exploit successfully.
Mitigation strategies should focus on implementing robust input validation and output encoding mechanisms within the application's client-side logic. Developers must ensure that all dynamic content is properly encoded before being rendered in the DOM to prevent script injection. Additionally, deploying a Content Security Policy can help mitigate the impact by restricting the sources from which scripts are allowed to load and execute. Regular security audits and static code analysis tools should be employed to identify similar patterns of unsafe DOM manipulation across the application's JavaScript files. Keeping Adobe Experience Manager updated with the latest patches provided by the vendor is also critical, as these updates often include fixes for such client-side vulnerabilities that address the underlying input handling flaws.
