AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:N
PR:H because injection needs a high-privileged account, UI:R because a victim must browse the page, S:C as script runs in the victim's browser scope; no availability impact.

Adobe Experience Manager Forms JEE is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a high-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, potentially gaining elevated access or control over the victim's account or session. Scope is changed.

AnalysisAI
Stored cross-site scripting in Adobe Experience Manager 6.5 Forms JEE and 6.5 LTS Forms JEE lets a high-privileged, authenticated attacker plant malicious JavaScript inside form fields that executes in a victim's browser when the poisoned form page is rendered, with a scope change that can extend impact to the victim's session or account. The CVSS vector confirms the prerequisites: PR:H means the attacker must already hold an elevated AEM account able to write form content, and UI:R means a victim must actively browse to the affected page, so realistic exposure is limited to malicious insiders or attackers who have already compromised high-privilege AEM credentials. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a HIGH-privileged authenticated account in Adobe Experience Manager Forms JEE (6.5 or 6.5 LTS) capable of writing to form fields - this is not an unauthenticated flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but constrained-priority issue, not a drop-everything emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch status: patch available per vendor advisory - apply the fixed build for Adobe Experience Manager 6.5 Forms JEE and 6.5 LTS Forms JEE identified in Adobe security bulletin APSB26-151 (https://helpx.adobe.com/security/products/aem-forms/apsb26-151.html); the exact fixed version number is not specified in the available input data, so confirm the target build against that advisory before upgrading rather than assuming a version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, confirm which AEM 6.5 Forms JEE and 6.5 LTS Forms JEE instances are internet- or partner-facing, inventory the accounts holding form authoring privileges, and reduce that group to the minimum set of trusted administrators; review recent form content and publish history for unexpected changes, and enable or tighten audit logging on those authoring actions. …
