Summary

CVE-2026-60199 is a critical vulnerability in the Core component of Oracle WebLogic Server, disclosed on July 21, 2026 as part of Oracle’s July 2026 Critical Patch Update. The flaw allows unauthenticated attackers with network access to fully compromise affected WebLogic Server instances over HTTP, with no privileges or user interaction required, earning a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Affected component: Core component of Oracle WebLogic Server
  • Attack vector: Network (HTTP) — remotely exploitable from the internet with no authentication and no user interaction required
  • Exploitation complexity: Low; Oracle’s advisory describes the vulnerability as "easily exploitable"
  • Impact: Full compromise of confidentiality, integrity, and availability of the affected server (CVSS C:H / I:H / A:H), consistent with complete system takeover
  • Root cause: The specific technical root cause has not yet been publicly disclosed; no CWE identifier has been assigned in the CVE record

Affected software

  • Oracle WebLogic Server 12.2.1.4.0
  • Oracle WebLogic Server 14.1.1.0.0
  • Oracle WebLogic Server 14.1.2.0.0
  • Oracle WebLogic Server 15.1.1.0.0

Severity

CVSS v3.1 Base Score: 9.8 (Critical)
Vector: 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 Oracle’s July 2026 Critical Patch Update, which addresses this vulnerability across all four affected versions. Patches are distributed through Oracle’s Fusion Middleware patch availability documentation linked from the official CPU advisory.
  • If immediate patching is not feasible: Restrict network-level access to WebLogic listener ports (typically TCP 7001 and 7002) to trusted IP ranges only. Disable or block external access to the WebLogic Administration Console and T3/IIOP endpoints at the perimeter firewall until patching can be completed.

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.
