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 low-privileged attackers to execute arbitrary JavaScript within a victim's browser by inducing them to visit a specially crafted AEM webpage, with the scope crossing the AEM origin boundary into the browser's security context. All three supported deployment tracks are affected: AEM as a Cloud Service through the 2026.7.0 release cycle, AEM 6.5 through 6.5.24, and AEM 6.5 LTS through SP2. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a low-privileged AEM account (content author, contributor, or reviewer role) sufficient to craft or deliver a DOM-injecting payload - this is confirmed by the PR:L metric in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium score accurately reflects constrained individual impact (C:L/I:L per vector) but understates aggregate risk in environments with large AEM author populations, where the social-engineering step is easier to execute. … 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 | Vendor-released patch per Adobe advisory APSB26-98 (https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html); AEM 6.5 customers should upgrade beyond version 6.5.24 by applying the remediation fix pack referenced in the advisory, AEM 6.5 LTS customers should apply beyond SP2, and Cloud Service customers should confirm their managed environment has been advanced past the 2026.7.0 release cycle (Adobe typically rolls Cloud Service updates automatically, but tenants should verify via the Adobe Cloud Manager console). … Detailed patch versions, workarounds, and compensating controls in full report. |
