Lifecycle Timeline
2DescriptionCVE.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 XSS in Adobe Experience Manager allows low-privileged authenticated attackers to inject malicious JavaScript into vulnerable form fields, where it persists server-side and executes in any victim's browser upon visiting the affected page. Three release tracks are affected: AEM as a Cloud Service through 2026.7.0, AEM 6.5 through 6.5.24, and AEM 6.5 LTS through SP2. The scope-changed impact means attacker-controlled scripts run in victim browser contexts - including those of administrators - enabling session hijacking, credential theft, or unauthorized actions on behalf of higher-privileged users. No public exploit or CISA KEV listing identified at time of analysis.
Technical ContextAI
Adobe Experience Manager (AEM) is a Java-based enterprise content management platform used broadly for web publishing, digital asset management, and multi-channel content delivery. CWE-79 (Improper Neutralization of Input During Web Page Generation) identifies the root cause: user-supplied input in one or more AEM form fields is stored without sufficient sanitization and later rendered in the browser without proper output encoding. This is a classic persistent/stored XSS pattern - distinct from reflected XSS in that the payload survives page reloads and affects every user who browses to the affected content, not just the originating attacker. The scope change metric (S:C) in the CVSS vector is consistent with this cross-user impact: the vulnerable component is the AEM authoring backend, while the impact materializes in a different security principal's browser session.
RemediationAI
Apply the fixes documented in Adobe Security Advisory APSB26-98 (https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html). For AEM as a Cloud Service, update to the release succeeding 2026.7.0 via Adobe's cloud pipeline; cloud customers may receive this automatically. For AEM 6.5, apply the patch bringing the instance beyond 6.5.24. For AEM 6.5 LTS, upgrade beyond SP2. Exact fix build numbers should be confirmed directly against APSB26-98, as these were not enumerated in the available intelligence. Where patching is delayed, restrict form-field editing permissions to fully trusted internal accounts only - removing contributor access for agencies or external users eliminates the low-privilege attacker path. Deploying a strict Content Security Policy (CSP) header that limits JavaScript execution to known origins reduces exfiltration impact but does not remediate the underlying injection flaw. Enabling AEM's built-in XSS Protection API (AntiSamy/XSSAPI) for all custom form components, if not already enforced site-wide, is a compensating development control.
