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 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 involves manipulating the DOM environment through a crafted webpage designed to trigger the vulnerable script execution when accessed by an authenticated user interacting with the Adobe Experience Manager interface.
The operational impact of this vulnerability centers on the potential for session hijacking, credential theft, and unauthorized actions performed under the victim's identity. By executing arbitrary JavaScript in the context of the trusted domain, an attacker can bypass same-origin policy restrictions to access sensitive data stored in cookies or local storage, redirect users to phishing sites, or deface the application interface. The requirement for user interaction indicates that this is not a remote code execution vulnerability but rather relies on social engineering tactics where the victim must visit a maliciously crafted URL or webpage while logged into Adobe Experience Manager.
From an offensive security perspective, this exploitation technique aligns with MITRE ATT&CK techniques related to Client-side Injection and Web Session Manipulation. The attacker leverages the trust that users place in the application's domain to escalate privileges or exfiltrate data without needing direct server-side access. This changes the scope of impact from a simple input validation error to a broader security compromise affecting user sessions and potentially sensitive enterprise content managed within the platform.
Mitigation strategies should focus on implementing robust output encoding for all dynamic content rendered in the browser, ensuring that special characters are escaped before being inserted into the DOM. Developers must also enforce strict Content Security Policy headers to restrict the sources from which scripts can be loaded and executed. Additionally, Adobe has released patches addressing this vulnerability, so administrators should apply the latest updates immediately. User awareness training is also recommended to help identify suspicious links or pages that might attempt to exploit such client-side flaws through social engineering campaigns targeting authenticated users of the platform.
