DescriptionCVE.org

Adobe Experience Manager is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-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. Scope is changed.

AnalysisAI

Affected deployments include AEM 6.5 through version 6.5.24, AEM 6.5 LTS through SP2, and AEM as a Cloud Service through the 2026.7.0 release. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold a valid low-privileged AEM account with permission to author or edit content in forms or page components - this is a standard content contributor role in most AEM deployments. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 5.4 score reflects a meaningful but bounded risk profile: network-reachable (AV:N), low complexity (AC:L), low-privilege attacker (PR:L), user interaction required (UI:R), scope change (S:C), with limited confidentiality and integrity impact (C:L/I:L/A:N). … 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 Consult Adobe Security Bulletin APSB26-98 (https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html) for the specific patched builds. … Detailed patch versions, workarounds, and compensating controls in full report.
