CVE-2026-75692 in Experience Manager
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 into the Document Object Model without proper encoding. The attack vector involves manipulating the DOM environment through a crafted webpage designed to trigger the vulnerable script execution when accessed by an authenticated user. Unlike server-side injections, this vulnerability operates entirely within the client's browser session, leveraging the trust relationship between the browser and the Adobe Experience Manager interface to bypass same-origin policy restrictions effectively.
The operational impact of exploiting this vulnerability is significant because it enables attackers to perform actions on behalf of the victim without their knowledge or consent. By executing arbitrary JavaScript in the context of the trusted application, an attacker can steal sensitive session cookies, capture keystrokes, redirect users to malicious sites, or deface the user interface. Since exploitation requires user interaction such as visiting a specific crafted URL, this aligns with ATT&CK technique T1059.007, which covers JavaScript execution in web browsers. The scope change indicates that the vulnerability may allow for broader access than initially anticipated, potentially escalating from simple script injection to more complex attacks like session hijacking or data exfiltration if combined with other vulnerabilities or social engineering tactics.
Mitigation strategies must focus on both immediate remediation and long-term defensive posture improvements. Administrators should apply the latest security patches provided by Adobe for Experience Manager as soon as they become available, ensuring that all instances are updated to versions where this input validation flaw has been corrected. From a development perspective, implementing strict output encoding and context-aware sanitization libraries is essential to prevent raw user input from being interpreted as executable code within the DOM. Additionally, deploying Content Security Policy headers can significantly reduce the impact of successful XSS attacks by restricting the sources from which scripts are allowed to load and execute. Regular security training for developers regarding secure coding practices and automated static analysis tools that detect potential injection points will further strengthen the application's resilience against such client-side threats.
