CVE-2026-75700 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 vulnerability classified as a Document Object Model based Cross-Site Scripting flaw, which allows for the execution of arbitrary JavaScript code within the security context of the vulnerable application. This type of vulnerability arises when an web application processes user-supplied input without proper validation or encoding before updating the DOM environment dynamically. In this specific instance, the underlying mechanism fails to adequately sanitize data that is subsequently used in a way that permits script injection. The technical nature of this flaw involves the browser interpreting injected malicious scripts as legitimate code belonging to the page's origin, thereby bypassing same-origin policy protections and granting the attacker elevated privileges within the application interface.
The operational impact of exploiting this vulnerability centers on the ability for an adversary to manipulate the victim's browsing session through social engineering tactics. Since exploitation requires user interaction, typically in the form of visiting a crafted webpage or clicking a malicious link, the attack vector is considered remote but interactive. Once triggered, the injected JavaScript can perform various hostile actions such as stealing sensitive cookies and authentication tokens, hijacking active sessions, performing unauthorized actions on behalf of the victim, or redirecting the user to phishing sites designed to harvest credentials. The change in scope indicates that the impact may extend beyond simple data theft to potentially affecting other applications sharing the same domain context if cookie isolation is not strictly enforced by modern browser security features.
From a classification perspective, this vulnerability aligns with CWE-79, which describes Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. Specifically, it falls under the subcategory of DOM-based XSS where the vulnerability exists in client-side code rather than server-side processing. In terms of offensive security frameworks, this activity maps to MITRE ATT&CK technique T1059 which covers Command and Scripting Interpreter execution via browser scripts such as JavaScript or VBScript. Understanding these mappings helps organizations prioritize remediation efforts based on standardized risk assessments and known attack patterns observed in the wild against enterprise content management systems like Adobe Experience Manager.
Mitigation strategies for this vulnerability require a multi-layered approach focusing on both immediate patching and long-term secure coding practices. Administrators should immediately apply the latest security updates provided by Adobe to address the specific code path responsible for the DOM manipulation flaw. Beyond patching, developers must implement strict input validation and output encoding mechanisms that ensure all user-supplied data is treated as plain text rather than executable code when inserted into the DOM. Utilizing Content Security Policy headers can also significantly reduce the impact of successful XSS attacks by restricting the sources from which scripts are allowed to load and execute. Regular security audits and static application security testing should be integrated into the development lifecycle to detect similar patterns before deployment, ensuring that future iterations of Adobe Experience Manager remain resilient against DOM-based injection techniques.
