Summary

CVE-2026-70998 is a critical, unauthenticated vulnerability in the Endeca Application Controller (EAC) component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0. It allows a remote attacker with no credentials to gain unauthorized access to critical data over HTTP, and Oracle rates it 9.3 (Critical) on the CVSS v3.1 scale. It was disclosed as part of Oracle’s August 2026 Critical Security Patch Update.

Technical details

  • Root cause: an easily exploitable flaw in the Endeca Application Controller component that fails to properly restrict access to accessible data.
  • Trigger conditions: no authentication or user interaction is required; the attacker only needs network access to the exposed HTTP interface.
  • Attack vector: network-based exploitation over HTTP (AV:N, AC:L, PR:N, UI:N).
  • Impact: successful exploitation can result in unauthorized access to critical data, or complete access to all data accessible by Oracle Commerce Guided Search / Oracle Commerce Experience Manager. The vulnerability has a "Scope: Changed" rating, meaning impact can extend beyond the vulnerable component itself; confidentiality impact is High and integrity impact is Low, with no availability impact.

Affected software

  • Oracle Commerce Guided Search / Oracle Commerce Experience Manager, version 11.4.0 (Endeca Application Controller component)

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N

Mitigation and recommended actions

  • Immediate: apply the fix provided in Oracle’s August 2026 Critical Security Patch Update for Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0.
  • If immediate patching is not possible: restrict network access to the Endeca Application Controller and Oracle Commerce Guided Search / Experience Manager HTTP interfaces to trusted internal networks only, and monitor for anomalous unauthenticated requests to these services until the patch can be 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.
