Summary

CVE-2026-70997 is a critical, unauthenticated remotely exploitable vulnerability in the Experience Manager component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager version 11.4.0. The flaw allows an attacker with network access via HTTP and no credentials to gain unauthorized access to critical data and to cause the affected service to hang or crash repeatedly. Oracle disclosed the issue in its August 2026 Critical Security Patch Update (CSPU) with a CVSS v3.1 base score of 9.1 (Critical).

Technical details

  • Root cause: A flaw in the Experience Manager component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager that fails to properly restrict access to sensitive functionality/data.
  • Attack vector: Remote, over HTTP, against the Experience Manager component — no authentication or user interaction required.
  • Attack complexity: Low — Oracle rates the flaw as easily exploitable.
  • Impact: Successful exploitation grants unauthorized access to all data accessible to Oracle Commerce Guided Search / Oracle Commerce Experience Manager (high confidentiality impact) and can cause a hang or frequently repeatable crash of the component (high availability impact). There is no integrity impact, and the vulnerability scope is "Unchanged" (impact is confined to the vulnerable component).
  • Exploitability: Oracle’s CPU table marks this CVE as remotely exploitable without authentication.

Affected software

  • Oracle Commerce Guided Search / Oracle Commerce Experience Manager — version 11.4.0

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

Mitigation and recommended actions

  • Immediate: Apply the Oracle Critical Security Patch Update (CSPU) for August 2026, which addresses CVE-2026-70997 in Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0. Oracle strongly recommends applying the fixes as soon as possible.
  • If immediate patching is not possible: Restrict network access to the Experience Manager component/HTTP interfaces to trusted internal networks only, and monitor for unusual or unauthenticated requests to Oracle Commerce Guided Search / Experience Manager endpoints until the patch can be applied. Oracle notes that in some cases protection can also come from restricting network access, though patching remains the primary remediation.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
