Summary
CVE-2026-70953 is a critical, unauthenticated remote code execution vulnerability in the Dynamo Application Framework component of Oracle Commerce Platform. Oracle rates it 9.8 (Critical) on CVSS v3.1, and it can be exploited over the network with no authentication or user interaction, potentially resulting in complete compromise of the affected system. The vulnerability was disclosed by Oracle in its August 2026 Critical Security Patch Update.
Technical details
- Root cause: A flaw in the Dynamo Application Framework component of the Oracle Commerce Platform product.
- Trigger conditions: No authentication or prior access is required; the flaw is exploitable purely via network access to the affected service.
- Attack vector: Network (TCP), as designated in the CVSS vector (AV:N), with low attack complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N) required.
- Impact: Successful exploitation can result in full takeover of the Oracle Commerce Platform, with high impact to confidentiality, integrity, and availability.
Affected software
- Oracle Commerce Platform, version 11.4.0 (Dynamo Application Framework component)
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the fix provided by Oracle in the August 2026 Critical Security Patch Update for Oracle Commerce Platform 11.4.0. Oracle strongly recommends applying the patch as soon as possible, as the update addresses multiple remotely exploitable vulnerabilities.
- If immediate patching is not possible: Restrict network access to Oracle Commerce Platform instances (e.g., via firewall rules or network segmentation) to trusted hosts only, and monitor exposed instances for unusual TCP traffic or exploitation attempts until the patch can be applied.
