DescriptionCVE.org

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.

AnalysisAI

Stored Cross-Site Scripting in Adobe Experience Manager allows a low-privileged authenticated attacker to inject persistent malicious JavaScript into vulnerable form fields. When any user - including higher-privileged administrators - browses to the page containing the injected payload, the script executes in their browser context, crossing scope boundaries into the victim's session. Affected versions span AEM 6.5 through 6.5.24, AEM as a Cloud Service through 2026.7.0, and AEM 6.5 LTS through SP2, as confirmed by APSB26-98. No public exploit code or active exploitation has been identified at time of analysis.

Technical ContextAI

Adobe Experience Manager (AEM) is an enterprise-grade content management system used for building and managing web properties. CWE-79 (Improper Neutralization of Input During Web Page Generation) applies here: user-supplied content submitted to form fields is stored in AEM's content repository (JCR/Oak) without adequate sanitization or output encoding, and is subsequently rendered back to other users' browsers unescaped. The CVSS scope-changed (S:C) flag reflects the canonical stored-XSS model: the vulnerability exists in AEM's form rendering layer, but the impact escapes into the victim's browser execution environment, a separate security principal. Affected CPE coverage spans AEM 6.5 on-premise (≤6.5.24), AEM 6.5 LTS (≤SP2), and AEM as a Cloud Service (≤2026.7.0).

RemediationAI

Apply the patches documented in Adobe security bulletin APSB26-98 at https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html. Based on the affected version ranges provided (≤6.5.24 for AEM 6.5, ≤2026.7.0 for Cloud Service, ≤SP2 for AEM 6.5 LTS), the expected fix targets are AEM 6.5.25+, AEM as a Cloud Service 2026.8.0+, and AEM 6.5 LTS SP3+, but these specific versions are inferred from the boundary data and not independently confirmed from the provided input - consult the APSB26-98 advisory directly for authoritative fix version numbers. As a compensating control prior to patching, restrict AEM author-tier access to trusted users only and review content contributor permissions to remove unnecessary accounts. AEM's built-in XSS protection filters (AntiSamy/OWASP ESAPI integration) should be verified as enabled and up to date in the AEM Security Checklist configuration.
