Adobe Experience Manager: Code injection enabling arbitrary code execution
Summary
Adobe Experience Manager (AEM) as a Cloud Service and AEM 6.5 / 6.5 LTS contain a code injection flaw (CWE-94). An attacker with network access and a low-privileged account can execute arbitrary code in the context of the current user, without user interaction, and with a changed scope (CVSS 9.9, critical). Adobe fixes the issue in security bulletin APSB26-189, published November 10, 2026.
Affected
- AEM as a Cloud Service: 2026.10.29023 and earlier
- AEM 6.5: Service Pack 25 and earlier
- AEM 6.5 LTS: Service Pack 3 and earlier
Fixed in
- AEM as a Cloud Service: 2026.10.29251
- AEM 6.5: Cumulative Hotfix for GRANITE-75052 (SP23 to SP25)
- AEM 6.5 LTS: Cumulative Hotfix for GRANITE-75052 (SP1 to SP3)
- Note: the CVE record lists GRANITE-75398 for 6.5 and 6.5 LTS SP3; verify the hotfix name in the bulletin before patching.
Workaround
Unknown. No vendor workaround is listed; apply the fix.
Exploitation
- Adobe states it is not aware of any exploits in the wild for the issues in APSB26-189.
- OffSeq (as of November 10, 2026, third-party source) reports no known exploitation.
- No public proof of concept found; CISA KEV status not verified.
Our recommendation
- Identify all AEM instances and versions, and confirm whether they run as Cloud Service or as 6.5 / 6.5 LTS.
- Apply the fixed release or cumulative hotfix from APSB26-189 with priority.
- Keep author instances off the internet; review low-privileged accounts, including self-registration.
- Monitor logs for unusual code execution or unexpected changes on AEM instances until patched.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
