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

Stored Cross-Site Scripting in Adobe Experience Manager (AEM) allows a low-privileged authenticated attacker to inject persistent malicious JavaScript into vulnerable form fields, which executes in any victim's browser that renders the affected page. The vulnerability affects AEM 6.5 LTS through SP2, AEM 6.5 through 6.5.24, and AEM as a Cloud Service through 2026.7.0. …

Vulnerability AssessmentAI

Exploitation The attacker must hold a low-privileged AEM account with sufficient permissions to submit content to vulnerable form fields (PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 5.4 (Medium) reflects realistic constraints: PR:L requires the attacker to hold a low-privileged AEM account, and UI:R requires a separate victim to browse the injected page - these two prerequisites meaningfully reduce real-world exploitability compared to unauthenticated or no-interaction XSS. … 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 fixes detailed in Adobe Security Bulletin APSB26-98 at https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html. … Detailed patch versions, workarounds, and compensating controls in full report.
