CVE-2026-48253 is a DOM-based Cross-Site Scripting (CWE-79) vulnerability in Adobe Experience Manager as a Cloud Service. An attacker can exploit this by manipulating the DOM environment, causing malicious JavaScript to execute within the victim's browser context. The attack requires user interaction, meaning the victim must visit a specially crafted webpage. The vulnerability affects the confidentiality and integrity of data but does not impact availability. The scope of the vulnerability is changed, indicating that the vulnerability affects components beyond the initially vulnerable component.

Successful exploitation could lead to the execution of arbitrary JavaScript in the context of the victim's browser, potentially allowing the attacker to steal sensitive information or perform actions on behalf of the user. The confidentiality and integrity of data may be compromised, but availability is not affected. The attack requires user interaction, limiting the ease of exploitation.
