CVE-2026-75715 in Experience Manager as a Cloud Service
Summary
by MITRE • 09/09/2026
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 specific type of injection occurs when an web application processes user-supplied data without proper validation or encoding before updating the DOM environment dynamically. In this instance, the vulnerability stems from insufficient sanitization of input sources that are reflected into the HTML document structure, enabling a malicious actor to inject executable scripts rather than harmless text content. The presence of such a flaw indicates a failure in implementing robust output encoding strategies for dynamic content insertion points within the application interface.
The operational impact of this vulnerability is significant because it compromises the integrity and confidentiality of user sessions associated with Adobe Experience Manager. By successfully exploiting this weakness, an attacker can bypass same-origin policy restrictions to access sensitive data stored locally by the browser, such as session cookies, authentication tokens, or personally identifiable information entered into forms. Furthermore, the ability to execute arbitrary JavaScript allows for more sophisticated attacks including keylogging, credential harvesting through fake login prompts, and redirection of users to malicious phishing sites designed to steal credentials. The scope change noted in the description suggests that the impact may extend beyond simple data theft to potentially affecting other parts of the application or even adjacent systems if combined with additional vectors like cross-site request forgery.
Exploitation of this vulnerability requires active user interaction, specifically necessitating that a victim visits a webpage crafted by an attacker containing malicious payloads designed to trigger the DOM manipulation flaw. This dependency on social engineering means that direct remote exploitation without any prior engagement from the target is not feasible through this vector alone. However, if Adobe Experience Manager instances are accessible via public URLs or embedded within trusted third-party sites, attackers can leverage phishing campaigns, compromised websites, or malicious advertisements to deliver the exploit code. The requirement for user interaction does not mitigate the severity of the issue but rather defines the attack surface and necessitates awareness-based defenses alongside technical controls.
To mitigate this risk, developers must implement strict input validation and output encoding practices that adhere to industry standards such as CWE-79, which covers improper neutralization of input during web page generation. It is critical to ensure that all dynamic content inserted into the DOM is properly encoded according to the context in which it appears, whether HTML entity encoding for text nodes or URL encoding for attribute values. Additionally, adopting Content Security Policy headers can significantly reduce the impact by restricting the sources from which scripts are allowed to load and execute. Regular security audits focusing on client-side code paths and automated static analysis tools configured to detect DOM-based XSS patterns should be integrated into the development lifecycle to prevent similar vulnerabilities in future releases of Adobe Experience Manager.
