Summary

CVE-2026-70997 is a critical, unauthenticated vulnerability in the Experience Manager component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager, version 11.4.0. Oracle describes it as an easily exploitable flaw that allows an attacker with network access via HTTP, and no authentication, to gain unauthorized access to critical data and cause denial-of-service conditions. The flaw carries 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.
  • Trigger conditions: exploitable over HTTP by an unauthenticated, remote attacker; no user interaction or privileges required.
  • Attack vector: Network (AV:N), Attack Complexity: Low (AC:L).
  • Impact: high confidentiality impact (unauthorized access to critical data) and high availability impact (denial-of-service); no integrity impact.

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 fix provided by Oracle in the August 2026 Critical Security Patch Update (CSPU) for Oracle Commerce Guided Search / Oracle Commerce Experience Manager version 11.4.0.
  • If patching cannot be applied immediately, restrict network access to the Experience Manager component to trusted hosts/networks only, and monitor for anomalous unauthenticated HTTP requests against Oracle Commerce Experience Manager endpoints until the patch is applied.

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.
