Adobe Experience Manager is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this issue by manipulating the DOM environment to execute malicious JavaScript within the context of the victim's browser. Exploitation of this issue requires user interaction in that a victim must visit a crafted webpage. Scope is changed.
AnalysisAI
DOM-based Cross-Site Scripting in Adobe Experience Manager allows a low-privileged network attacker to execute arbitrary JavaScript in a victim's browser by luring them to a crafted webpage that manipulates the client-side DOM environment. The scope-changed CVSS vector (S:C) confirms the malicious script executes in the victim's browser security context rather than the server, enabling session hijacking, credential theft, or UI redress against AEM users. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a low-privilege authenticated account on the AEM instance (PR:L per CVSS), sufficient to craft or control a URL or link that will be processed by vulnerable client-side DOM manipulation code. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.4 (Medium) reflects the balanced risk profile: network-reachable (AV:N), low complexity (AC:L), but requiring low privileges (PR:L) and mandatory user 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. |
| Remediation | Apply the patches documented in Adobe Security Bulletin APSB26-98 (https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
