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 (AEM) allows an authenticated attacker to execute arbitrary JavaScript within a victim's browser by enticing them to visit a crafted URL, affecting AEM 6.5 through 6.5.24, AEM 6.5 LTS through SP2, and AEM as a Cloud Service through the July 2026 release. The CVSS scope change (S:C) signals that the injected script escapes AEM's own browser origin boundary, enabling session hijacking or unauthorized CMS operations under the victim's identity. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: (1) the attacker holds at least a low-privileged Adobe Experience Manager account (CVSS PR:L - purely external, unauthenticated actors cannot exploit this directly); and (2) an authenticated AEM user with a meaningful privilege level must actively follow a crafted AEM URL or visit an attacker-controlled page that triggers the DOM manipulation payload (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium rating is proportionate for this class of vulnerability: the PR:L prerequisite (attacker needs a valid AEM account) and UI:R (victim must follow a crafted link) are meaningful friction points that reduce realistic exploitation probability compared to an unauthenticated, no-interaction vector. … 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 advisory APSB26-98 (https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
