CVE-2026-110081 in Experience Manager
Summary
by MITRE • 10/13/2026
Adobe Experience Manager is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field. Scope is changed.

Adobe Experience Manager contains a stored Cross-Site Scripting vulnerability that allows attackers with low privileges to inject malicious script code directly into application data stores through form fields. Unlike reflected XSS where payloads are delivered via URLs, this flaw persists on the server side because the injected content is saved and subsequently served back to other users without proper sanitization or encoding. This architectural characteristic means that a single successful injection can compromise multiple victims who access the affected pages, significantly expanding the attack surface beyond the initial point of entry. The vulnerability stems from insufficient validation mechanisms within the form processing logic, which fails to neutralize special characters such as angle brackets and quotes before rendering them in HTML contexts.
The operational impact of this flaw is severe because it enables persistent data manipulation and session hijacking scenarios. When a victim with higher privileges or different access levels views the compromised page, their browser executes the injected JavaScript within the security context of the Adobe Experience Manager application. This can lead to unauthorized actions being performed on behalf of the user, such as changing account settings, exfiltrating sensitive content stored in the system, or redirecting users to phishing sites. The ability for low-privileged attackers to achieve this outcome represents a significant escalation of privilege and trust boundary violation within the enterprise environment.
From a classification perspective, this vulnerability aligns with CWE-79 Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. Specifically it falls under the stored variant where malicious scripts are permanently stored in target servers via database calls or other input mechanisms. In terms of adversary tactics and techniques this behavior maps to ATT&CK technique T1059 Command and Control Execution which involves using scripting interpreters like JavaScript for lateral movement or data exfiltration, as well as T1189 Drive-by Client Compromise where users are tricked into visiting maliciously crafted pages. The persistence aspect also relates to T1505 Server Software Component which indicates the attacker is leveraging existing software components to maintain access and execute commands within the trusted environment.
Mitigation strategies must focus on both immediate remediation and long-term defensive posture improvements. Administrators should apply vendor-provided security patches immediately to address the specific input validation gaps in form handling modules. Beyond patching, implementing a Content Security Policy can help mitigate the impact by restricting the sources from which scripts are allowed to execute, thereby preventing many common XSS payloads even if they manage to bypass other controls. Additionally developers must enforce strict output encoding and context-aware escaping for all user-supplied data before it is rendered in HTML attributes or body content. Input validation should be implemented on both client and server sides with the server-side checks serving as the definitive security boundary since client-side protections can easily be circumvented by attackers using custom tools or browser extensions.
