CVE-2026-75687 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 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 implementation flaw stems from insufficient validation or sanitization of user-supplied input that is subsequently written directly into the Document Object Model without proper encoding. By manipulating the DOM environment through crafted web pages, an adversary can bypass standard security controls such as Content Security Policy if not strictly configured to prevent script execution in untrusted contexts. The vulnerability aligns with MITRE ATT&CK technique T1059.007, which covers JavaScript-based attacks, highlighting how attackers leverage native browser functionality to achieve arbitrary code execution on the client side.
The operational impact of this vulnerability is significant because it enables session hijacking, credential theft, and defacement of the user interface by executing scripts in a privileged context. Since exploitation requires user interaction, such as visiting a specially crafted webpage or clicking a malicious link, social engineering tactics are often employed to lure victims into triggering the exploit. Once executed, the injected script can access sensitive data stored in local storage or cookies, potentially leading to unauthorized access to Adobe Experience Manager administrative functions if the victim holds elevated privileges. This changes the scope of the attack from a simple information leak to a potential compromise of user sessions and application integrity, as the malicious code runs with the same permissions as legitimate scripts loaded by the platform.
Mitigation strategies should focus on implementing robust input validation and output encoding mechanisms within the Adobe Experience Manager configuration. Developers must ensure that all dynamic content is properly encoded before being rendered in the DOM to prevent script injection. Additionally, enforcing a strict Content Security Policy can significantly reduce the risk of successful exploitation by restricting the sources from which scripts are allowed to load and execute. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities across the application surface area. Keeping Adobe Experience Manager updated with the latest patches provided by the vendor is critical, as these updates often include fixes for known DOM-based XSS flaws that could otherwise be leveraged in targeted attacks against enterprise environments.
