2DescriptionCVE.org
Adobe Experience Manager is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid low-privilege AEM user account (PR:L) - anonymous unauthenticated access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.4 (Medium) accurately captures the constrained attack path: network-reachable (AV:N), low complexity (AC:L), but requiring a low-privilege account (PR:L) and victim interaction (UI:R). … 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. |
