CVE-2026-75652 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 application's domain. This specific flaw stems from insufficient validation or sanitization of user-supplied input that is subsequently used to update the Document Object Model without proper encoding. The vulnerability operates at the DOM level, meaning the script execution occurs directly in the victim's web browser rather than on the server side, which distinguishes it from reflected or stored XSS variants by relying entirely on client-side processing logic for its exploitation vector.
The operational impact of this vulnerability is significant because successful exploitation enables an attacker to bypass same-origin policy restrictions and access sensitive data protected by standard browser security models. An adversary can manipulate the DOM environment to steal session cookies, hijack user sessions, perform actions on behalf of the victim, or redirect users to malicious phishing sites. Since Adobe Experience Manager often handles critical content management tasks and administrative functions, compromising a valid user's session could lead to unauthorized modification of website content, defacement, or further lateral movement within an organization's digital infrastructure if privileged accounts are targeted.
Exploitation requires active user interaction as the victim must visit a crafted webpage controlled by the attacker. This typically involves social engineering tactics where the victim is lured into clicking a malicious link that contains exploit code in the URL parameters or form fields, which then triggers the DOM manipulation logic within Adobe Experience Manager's interface. The requirement for user interaction does not diminish the severity of the risk but rather defines the attack vector as an active exploitation scenario dependent on human error or deception to initiate the compromise sequence.
Mitigation strategies should focus on implementing robust input validation and output encoding mechanisms that strictly adhere to security best practices defined by industry standards such as OWASP guidelines for preventing XSS attacks. Developers must ensure that all dynamic content is properly encoded before being rendered in the DOM, utilizing context-aware escaping techniques appropriate for HTML attributes, JavaScript strings, or CSS properties. Additionally, deploying Content Security Policy headers can provide a defense-in-depth layer by restricting the sources from which scripts are allowed to execute, thereby mitigating the impact even if an injection attempt succeeds. Regular security assessments and code reviews targeting client-side logic are essential to identify and remediate such DOM-based vulnerabilities before they can be leveraged in production environments.
