CVE-2026-75694 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 relies on manipulating the DOM environment, where untrusted data influences how a web page renders its content. By crafting a malicious webpage containing specially constructed scripts, an attacker can trigger this vulnerability when a victim interacts with the site or visits the crafted link.
The operational impact of this vulnerability is significant because it enables session hijacking, credential theft, and defacement of the application interface. Since the script executes in the context of the trusted Adobe Experience Manager domain, it inherits all privileges associated with that origin, including access to cookies, local storage, and authenticated sessions. This effectively bypasses same-origin policy protections, allowing the malicious code to perform actions on behalf of the victim user without their knowledge or consent. The requirement for user interaction means that social engineering tactics are often necessary to lure victims into visiting the exploit site, but once triggered, the attack proceeds automatically within the browser environment.
From a threat intelligence perspective, this vulnerability aligns with ATT&CK technique T1059, specifically sub-technique 007 which covers JavaScript execution. The exploitation chain typically involves delivering the malicious payload through phishing emails or compromised websites that redirect users to the crafted page containing the DOM manipulation script. Once executed, the attacker can exfiltrate sensitive data such as authentication tokens or personally identifiable information stored in browser storage mechanisms. This represents a critical risk for organizations relying on Adobe Experience Manager for content management and digital experience delivery, as it compromises the integrity of user sessions and potentially exposes backend systems if further lateral movement is attempted using stolen credentials.
Mitigation strategies should focus on both immediate remediation and long-term defensive posture improvements. The primary technical fix involves implementing strict input validation and output encoding to ensure that any data rendered into the DOM is properly escaped, preventing script injection. Developers must adopt secure coding practices such as Content Security Policy (CSP) headers to restrict the sources from which scripts can be loaded and executed. Additionally, enabling HTTP-only flags on cookies prevents client-side scripts from accessing session identifiers, thereby reducing the impact of successful XSS attacks. Regular security audits and static code analysis tools should be employed to detect similar DOM-based vulnerabilities before deployment. Users are advised to keep their browsers updated to leverage built-in protections against known exploitation techniques and to exercise caution when clicking links from untrusted sources.
