CVE-2026-27227: Cross-site Scripting (Stored XSS) (CWE-79) in Adobe Adobe Experience Manager as a Cloud Service

CVE-2026-27227 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager as a Cloud Service. It allows attackers with low privileges to inject malicious JavaScript into form fields that are stored and later executed in the browsers of users who visit the affected pages. The vulnerability affects versions up to 2026.7.0, SP2, and 6.5.24. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, changed scope, and impacts confidentiality and integrity with no impact on availability.

Successful exploitation could lead to execution of arbitrary JavaScript in the context of the victim's browser, potentially allowing theft of sensitive information or session tokens, or other malicious actions within the scope of the affected web application. The vulnerability affects confidentiality and integrity but not availability. The scope change indicates that the vulnerability allows an attacker to affect resources beyond their initial privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since this is a cloud service, verify with Adobe if the service has been patched server-side. Until a fix is confirmed, restrict access to vulnerable forms and apply input validation or sanitization where possible to mitigate injection of malicious scripts.
