CVE-2026-75702 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 application processes user-supplied input and writes it to the DOM without proper validation or encoding, thereby enabling malicious scripts to run in the victim's browser environment rather than on the server itself. The vulnerability stems from a failure to adequately sanitize dynamic content that is rendered into the page structure, creating a pathway for attackers to inject executable payloads directly into the client-side execution flow.
The operational impact of this vulnerability centers on the potential compromise of user sessions and sensitive data residing within the Adobe Experience Manager interface. By executing malicious JavaScript in the context of the victim's browser, an attacker can perform actions such as stealing session cookies, hijacking active administrative or authoring sessions, performing unauthorized actions on behalf of the user, or redirecting the user to phishing sites designed to harvest credentials. Since Adobe Experience Manager is often used for managing critical digital assets and content workflows, a successful exploitation could lead to significant business disruption, data leakage, or further lateral movement within an organization's network if session tokens are compromised.
Exploitation of this flaw requires active user interaction, specifically necessitating that the victim visits a specially crafted webpage controlled by the attacker. This dependency on social engineering or drive-by techniques means that while the vulnerability is serious, it does not allow for fully automated remote code execution without some form of诱骗ing the target to interact with malicious content. The scope change noted in the description indicates that the impact may extend beyond simple data theft to potentially affecting other applications sharing the same domain cookies if proper isolation mechanisms are not enforced by the browser or application configuration, thereby increasing the blast radius of a successful attack.
To mitigate this risk, organizations should ensure they have applied the latest security patches and updates provided by Adobe for their specific version of Experience Manager. From an architectural perspective, implementing strict Content Security Policy headers can significantly reduce the impact of DOM-based XSS by restricting the sources from which scripts are allowed to execute. Additionally, developers must enforce rigorous input validation and output encoding practices on all client-side code that handles dynamic data, ensuring that any user-supplied values are properly escaped before being inserted into the DOM. Regular security assessments and penetration testing focused on cross-site scripting vectors should also be conducted to identify similar weaknesses in custom components or integrations within the platform. This vulnerability aligns with CWE-79, which covers Improper Neutralization of Input During Web Page Generation, and is associated with MITRE ATT&CK technique T1059, specifically Command and Scripting Interpretation via JavaScript execution on client-side systems.
