CVE-2026-60780 – Unauthenticated Remote Compromise via SMTP – Oracle Workflow (E-Business Suite 1…

Be the first to know when new zero-days emerge:

Summary

CVE-2026-60780 is a high-severity vulnerability in the Internal Operations component of Oracle Workflow, a core component of Oracle E-Business Suite (EBS), disclosed as part of Oracle’s July 2026 Critical Patch Update. An unauthenticated remote attacker with network access via SMTP can exploit this flaw to fully compromise Oracle Workflow, with no authentication or user interaction required. Successful exploitation results in complete impact to confidentiality, integrity, and availability of the affected system.

Technical details

  • Affected component: Internal Operations within Oracle Workflow (Oracle E-Business Suite)
  • Attack vector: Network-reachable via SMTP; no privileges or user interaction required (PR:N, UI:N)
  • Attack complexity: High (AC:H) — Oracle classifies this as "difficult to exploit," meaning specific conditions must be present; however, this is not a disqualifying factor for organizations with internet-exposed EBS deployments
  • Impact: Successful exploitation can result in full takeover of Oracle Workflow, with high impact to confidentiality, integrity, and availability (C:H/I:H/A:H)
  • Exposure context: Approximately 950 Oracle E-Business Suite instances have been identified as internet-facing, making network-reachable SMTP-based attacks a realistic threat vector for organizations that have not restricted external access

Affected software

  • Oracle Workflow (Oracle E-Business Suite), versions 12.2.3 through 12.2.15

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 Oracle July 2026 Critical Patch Update. Oracle E-Business Suite customers should follow the Oracle EBS Release 12 Critical Patch Update Knowledge Document (My Oracle Support Note KA923) for environment-specific patch instructions.
  • Network mitigation: Where immediate patching is not feasible, restrict SMTP access to the Oracle Workflow Internal Operations component to trusted internal network segments only and block unauthenticated inbound SMTP from external networks.

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.
