Adobe Experience Manager: Stored Cross-Site Scripting in form fields
Summary
Adobe Experience Manager (Cloud Service, 6.5 and 6.5 LTS) contains a stored Cross-Site Scripting vulnerability in form fields. An attacker with a low-privileged account can store malicious JavaScript that runs in the browser of a user who opens the affected page. User interaction is required and the scope is changed. Adobe reports no known exploits in the wild.
Affected
- AEM Cloud Service: 2026.10.29023 and earlier
- AEM 6.5: Service Pack 25 (6.5.25) and earlier
- AEM 6.5 LTS: Service Pack 3 and earlier
Fixed in
- AEM Cloud Service: 2026.10.29251 (applied by Adobe)
- AEM 6.5: Cumulative Hotfix for GRANITE-75398 according to the CVE record; the Adobe bulletin names GRANITE-75052. Confirm the correct ID with Adobe.
- AEM 6.5 LTS: Fixed version unverified. Confirm with Adobe.
Workaround
- No vendor workaround known.
- Interim measure (own suggestion, not from Adobe): restrict who can write to the affected form fields.
Exploitation
- Adobe is not aware of any exploits in the wild.
- Not listed in the CISA KEV catalog. EPSS score 0.00371.
- No public proof of concept found; this does not rule out that one exists.
Our recommendation
- Check whether AEM 6.5 or 6.5 LTS is in use, and whether public forms or many content authors exist.
- Apply the matching hotfix or update on-premise instances once the correct hotfix ID is confirmed with Adobe.
- For Cloud Service, verify that the instance runs 2026.10.29251 or later.
- Limit write access to forms and monitor content changes for suspicious scripts.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
