Executive Summary

CVE-2026-48261 is a DOM-based Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager. DOM-based XSS occurs when a web application writes user-provided data to the Document Object Model (DOM) without proper sanitization, allowing attackers to manipulate the DOM environment.

In this case, an attacker could craft a malicious webpage or input that alters the DOM in a way that executes arbitrary JavaScript code in the victim's browser. The exploitation requires user interaction, meaning the victim must visit the attacker's crafted webpage or interact with a malicious link.

The scope of this vulnerability is marked as changed, indicating that the impact extends beyond the vulnerable component itself, potentially affecting other parts of the application or system.
