Summary

CVE-2026-83299 is a vulnerability in the Analytics Web General component of Oracle Business Intelligence Enterprise Edition (OBIEE) that allows an unauthenticated attacker with network access via HTTP to fully compromise the affected system. Oracle rates the flaw HIGH severity with a CVSS v3.1 base score of 8.1, and while it is classified as difficult to exploit, no authentication or user interaction is required to attempt an attack.

Technical details

  • The flaw resides in the Analytics Web General component of Oracle Business Intelligence Enterprise Edition.
  • It is remotely exploitable over HTTP without any authentication or user interaction.
  • Oracle characterizes the attack complexity as high, indicating exploitation requires specific conditions or attacker capabilities beyond simply reaching the exposed HTTP interface.
  • Successful exploitation can result in complete compromise of the confidentiality, integrity, and availability of Oracle BI Enterprise Edition.
  • The specific technical root cause (e.g., the exact code path or flaw class) has not been disclosed in the public CVE record.

Affected software

  • Oracle Business Intelligence Enterprise Edition, version 12.2.1.4.0

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 Oracle Critical Patch Update that addresses CVE-2026-83299 for Oracle Business Intelligence Enterprise Edition 12.2.1.4.0 as soon as it is available from Oracle’s official security alert channel.
  • If patching cannot be applied immediately: Restrict network exposure of OBIEE Analytics Web interfaces to trusted networks only (e.g., via VPN, firewall ACLs, or reverse proxy access controls), and monitor HTTP access logs for anomalous or unauthorized requests to the Analytics Web endpoints until the patch can be deployed.

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.
