Summary

CVE-2026-70978 is a critical, unauthenticated vulnerability in the Content Acquisition System component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager, version 11.4.0. The flaw allows an attacker with only network access over HTTP to compromise the system without any credentials or user interaction, resulting in unauthorized creation, deletion, and modification of critical data as well as unauthorized data exposure. Oracle rates the issue CRITICAL with a CVSS v3.1 base score of 9.1.

Technical details

  • Root cause: an exploitable weakness in the Content Acquisition System component of Oracle Commerce Guided Search / Experience Manager.
  • Trigger conditions: no authentication or user interaction is required; the vulnerability is described by Oracle as easily exploitable.
  • Attack vector: remote exploitation over HTTP/network access (AV:N).
  • Impact: high confidentiality impact (unauthorized access to data) and high integrity impact (unauthorized creation, deletion, or modification of critical data); no availability 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:H/A:N

Mitigation and recommended actions

  • Immediate: Apply the fix provided in Oracle’s Critical Security Patch Update for August 2026, which addresses CVE-2026-70978 for Oracle Commerce Guided Search / Experience Manager 11.4.0. Organizations should apply the corresponding patch as soon as possible.
  • If a patch cannot be applied immediately: restrict network access to the Content Acquisition System component to trusted internal networks only, and monitor exposed Oracle Commerce endpoints for unusual creation/modification/deletion activity until patched.

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.
