Summary

CVE-2026-71035 is a vulnerability in the Forge component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager that allows an unauthenticated attacker with network access via HTTP to compromise the system. Oracle rates the flaw as difficult to exploit, but a successful attack can result in complete takeover of the affected application, impacting confidentiality, integrity, and availability. The vulnerability affects version 11.4.0 and was disclosed by Oracle in August 2026.

Technical details

  • Root cause: a flaw in the Forge component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager.
  • Trigger conditions: exploitable over HTTP without authentication; Oracle notes attack complexity is high, meaning exploitation requires specific conditions to be met.
  • Attack vector: network, requiring no privileges and no user interaction.
  • Impact: successful exploitation can result in full takeover of Oracle Commerce Guided Search / Oracle Commerce Experience Manager, with high impact to confidentiality, integrity, and availability.

Affected software

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

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Apply the fix provided by Oracle in the August 2026 Critical Security Patch Update (cspuaug2026) for Oracle Commerce Guided Search / Oracle Commerce Experience Manager version 11.4.0.
  • If patching cannot be applied immediately: restrict network access to the Oracle Commerce Guided Search / Experience Manager Forge component to trusted networks only, and monitor HTTP traffic to affected endpoints for anomalous requests until the patch can be applied.

How IONIX identifies potentially affected assets

IONIX matches the following signals against data already collected when it crawled the asset; identifying the technology sends no request beyond that crawl.

  • HTTP response header x-atg-version: value matching an ATGPlatform/ version string
  • Raw response body: presence of a tag attribute containing _dyncharset

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.
