Summary

CVE-2026-73941 is a vulnerability in the Authentication Engine of Oracle Access Manager, a component of Oracle Fusion Middleware, that allows an unauthenticated, network-based attacker to gain unauthorized access to sensitive data. Oracle rates the flaw as easily exploitable, requiring no authentication or user interaction, and assigns it a CVSS v3.1 base score of 8.6 (High).

Technical details

  • Root cause: A flaw in the Authentication Engine component of Oracle Access Manager.
  • Trigger conditions: No privileges or user interaction are required; the attacker only needs network access to the exposed Oracle Access Manager instance.
  • Attack vector: Network, over HTTP, with low attack complexity (AV:N/AC:L/PR:N/UI:N).
  • Impact: Per Oracle’s own characterization, successful exploitation can result in "unauthorized access to critical data or complete access to all Oracle Access Manager accessible data." The CVSS vector reflects a scope change (S:C) with a high confidentiality impact and no impact to integrity or availability.

Affected software

  • Oracle Access Manager 12.2.1.4.0
  • Oracle Access Manager 14.1.2.1.0

Severity

  • CVSS v3.1 Base Score: 8.6 (High)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Apply the Oracle security patch addressing CVE-2026-73941 for the affected Oracle Access Manager releases (12.2.1.4.0 and 14.1.2.1.0), as published in Oracle’s security alert.
  • If patching cannot be applied immediately: Restrict network exposure of Oracle Access Manager endpoints to trusted networks only, and monitor Oracle Access Manager logs for anomalous authentication activity 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.
