Summary

CVE-2026-61145 is a critical, unauthenticated vulnerability in the Content Acquisition System component of Oracle Commerce Guided Search / Oracle Commerce Experience Manager version 11.4.0, disclosed as part of Oracle’s July 2026 Critical Patch Update (CPU). The flaw is remotely exploitable over HTTP with no privileges or user interaction required, and Oracle confirms that successful exploitation results in full takeover of the affected platform, earning a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Affected component: Content Acquisition System, an HTTP-accessible service within Oracle Commerce Guided Search / Experience Manager
  • Attack vector: Network-accessible via HTTP; no adjacent network position required
  • Authentication required: None — the vulnerability is exploitable by unauthenticated, remote attackers
  • Attack complexity: Low — no special conditions, configurations, or race conditions needed
  • User interaction: None required
  • Impact: Oracle states that successful exploitation results in complete takeover of Oracle Commerce Guided Search / Oracle Commerce Experience Manager, with high impact to confidentiality, integrity, and availability of the affected system

Affected software

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

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Apply the Oracle July 2026 Critical Patch Update (CPU) patch for Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Oracle’s CPU is the only vendor-confirmed fix for this vulnerability.
  • If immediate patching is not feasible: Restrict network access to the Content Acquisition System component via firewall rules or network segmentation. Limit HTTP exposure of Oracle Commerce Guided Search and Experience Manager services to trusted internal networks only, and block public internet access to these endpoints until the patch can be applied.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
