Summary

CVE-2026-46930 is a critical unauthenticated remote access vulnerability affecting Oracle In-Memory Cost Management for Discrete Industries (versions 12.2.12 through 12.2.15), a web-based module of Oracle E-Business Suite. Disclosed as part of Oracle’s June 2026 Critical Security Patch Update, the flaw allows unauthenticated network attackers to gain unauthorized read access to sensitive data as well as unauthorized creation, deletion, or modification of critical data within the affected application, earning a CVSS v3.1 base score of 9.1.

Technical details

  • Root cause: Oracle has not publicly disclosed the precise root cause; the vulnerability resides in the Internal Operations component of the module and requires no authentication to trigger.
  • Trigger conditions: An attacker with network access to the target system can exploit this vulnerability over HTTPS with low attack complexity and no user interaction required.
  • Attack vector: Remote, unauthenticated, via HTTPS (AV:N/AC:L/PR:N/UI:N). No local access, credentials, or victim interaction are necessary.
  • Impact: High confidentiality impact — unauthorized read access to all application-accessible data; high integrity impact — unauthorized creation, deletion, or modification of critical data. No availability impact.

Affected software

  • Oracle In-Memory Cost Management for Discrete Industries 12.2.12
  • Oracle In-Memory Cost Management for Discrete Industries 12.2.13
  • Oracle In-Memory Cost Management for Discrete Industries 12.2.14
  • Oracle In-Memory Cost Management for Discrete Industries 12.2.15

(All affected versions are components of Oracle E-Business Suite 12.2.x.)

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Mitigation and recommended actions

  • Immediate action: Apply the patches provided in the Oracle June 2026 Critical Security Patch Update (CSPU June 2026). Patch availability and installation instructions are documented in My Oracle Support Note KA923 (Oracle E-Business Suite Release 12 Critical Security Patch Update Knowledge Document, June 2026).
  • If patching cannot be applied immediately: Restrict network access to Oracle E-Business Suite interfaces at the perimeter. Ensure that Oracle EBS login pages and application endpoints are not exposed directly to the public internet. Apply strict firewall rules to limit access to trusted IP ranges only.
  • Oracle strongly recommends customers apply Critical Security Patch Update patches without delay.

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.
