Summary
CVE-2026-70980 is a critical vulnerability in Oracle Commerce Guided Search / Oracle Commerce Experience Manager, residing in the Content Acquisition System component. It allows an unauthenticated attacker with network access via HTTP to compromise and ultimately take over the affected system, with impact potentially extending to additional products due to a scope change. Oracle rates this as a CVSS v3.1 9.0 (Critical) issue, disclosed as part of the August 2026 Critical Security Patch Update.
Technical details
- Root cause: a flaw in the Content Acquisition System component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager that Oracle describes as "difficult to exploit."
- Trigger conditions: exploitation requires no authentication and no user interaction, but has high attack complexity, meaning specific conditions or attacker-controlled circumstances must exist for exploitation to succeed.
- Attack vector: network, via HTTP, with no privileges required.
- Impact: successful exploitation can result in complete takeover of Oracle Commerce Guided Search / Oracle Commerce Experience Manager; the CVSS scope is "Changed," indicating the vulnerability can affect resources beyond the vulnerable component itself, with high impact to confidentiality, integrity, and availability.
Affected software
- Oracle Commerce Guided Search / Oracle Commerce Experience Manager, version 11.4.0 (Content Acquisition System component)
Severity
- CVSS v3.1 Base Score: 9.0 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the Oracle Critical Security Patch Update for August 2026, which contains the fix for CVE-2026-70980 for the affected version (11.4.0) of Oracle Commerce Guided Search / Oracle Commerce Experience Manager.
- If patching cannot be performed immediately: Oracle states that in some cases it is possible to mitigate this vulnerability by blocking network protocol access needed to exploit the issue; review Oracle’s advisory for any component-specific network restriction guidance and restrict HTTP access to the Content Acquisition System interface to trusted networks until the patch is applied.
