CVE-2026-75637 is a DOM-based Cross-Site Scripting (XSS) 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. Exploitation requires the victim to visit a maliciously crafted webpage. The vulnerability affects versions up to 6.5.24 and related versions. The scope of the vulnerability is changed, indicating that the impact crosses security boundaries. The CVSS 3.1 base score is 5.4, reflecting medium severity with network attack vector, low attack complexity, low privileges required, user interaction required, and impact on confidentiality and integrity but not availability.

Successful exploitation can lead to execution of arbitrary JavaScript in the context of the victim's browser, potentially allowing theft of sensitive information or session tokens. The impact is limited to confidentiality and integrity with no direct availability impact. Exploitation requires user interaction (visiting a crafted webpage). No known exploits in the wild have been reported.
