Lifecycle Timeline

Adobe Experience Manager versions FP11.7 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an 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.
AnalysisAI
Stored Cross-Site Scripting in Adobe Experience Manager versions FP11.7 and earlier allows authenticated attackers to inject malicious JavaScript into form fields, which executes in victims' browsers with limited impact (confidentiality and integrity). The vulnerability requires user interaction (victim must view the affected page) and authenticated access, resulting in a CVSS 5.4 (medium) score. No public exploit code or active exploitation has been identified at time of analysis.
Technical ContextAI
This vulnerability exploits improper input validation and output encoding in Adobe Experience Manager's form field handling, classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The affected component fails to sanitize or encode user-supplied data before rendering it in the browser context, allowing attackers with authenticated access to inject arbitrary JavaScript that persists in the application's data store. When other users access pages containing these malicious form fields, their browsers execute the injected scripts in the security context of the AEM application, potentially allowing theft of session tokens, user credentials, or modification of page content.
RemediationAI
Upgrade Adobe Experience Manager to Feature Pack 12 or later, which is the first release series confirmed to address this vulnerability. Organizations unable to upgrade immediately should implement compensatory controls: restrict form field editing to a minimal set of trusted administrative accounts, enable browser-based Content Security Policy (CSP) headers to limit inline script execution, and audit existing form fields for suspicious JavaScript patterns. Refer to Adobe's official security advisory at https://helpx.adobe.com/security/products/aem-screens/apsb26-34.html for patched versions and additional mitigation guidance.
