Summary

CVE-2026-70905 is a critical vulnerability in Oracle Access Manager (Oracle Fusion Middleware) that allows an unauthenticated, remote attacker to compromise and fully take over the product via SAML. Oracle rates it CVSS 3.1 base score 9.8 (Critical), and it was published as part of the Oracle Critical Security Patch Update for August 2026.

Technical details

  • Root cause lies in the Agent infrastructure component of Oracle Access Manager.
  • The flaw is exploited over the network via SAML, with no authentication or user interaction required.
  • Oracle describes it as "easily exploitable."
  • Successful exploitation can result in full takeover of Oracle Access Manager, with high impact to confidentiality, integrity, and 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: 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 the patches for Oracle Access Manager provided in Oracle’s August 2026 Critical Security Patch Update (advisory cspuaug2026) for the affected 12.2.1.4.0 and 14.1.2.1.0 releases.
  • If patching cannot be performed immediately, restrict and monitor network access to SAML-related endpoints on internet-exposed Oracle Access Manager deployments until the patch is applied, and review Oracle’s advisory for any documented interim guidance.

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.
