Summary

CVE-2026-62635 is a critical, unauthenticated, network-exploitable vulnerability in the Security and Authentication component of Oracle Reports Developer (part of Oracle Fusion Middleware). It is remotely exploitable over HTTP without credentials or user interaction, and Oracle rates it as easily exploitable, with successful exploitation resulting in complete compromise of the host’s confidentiality, integrity, and availability.

Technical details

  • Root cause: Flaw in the Security and Authentication component of Oracle Reports Developer.
  • Trigger conditions: Exploitable by sending crafted requests over HTTP; no authentication or user interaction is required.
  • Attack vector: Network (AV:N), low attack complexity, no privileges required, no user interaction.
  • Impact: Complete takeover of the Oracle Reports Developer host, with high impact to confidentiality, integrity, and availability; scope is unchanged.

Affected software

  • Oracle Reports Developer, version 14.1.2.0.0

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 the Oracle Critical Patch Update for August 2026, which addresses CVE-2026-62635 for Oracle Reports Developer 14.1.2.0.0. Oracle states patches are available for this CVE.
  • If patching cannot be applied immediately: Restrict network access to the Oracle Reports Developer HTTP interface (e.g., the reports servlet) to trusted internal networks only, and monitor for unexpected inbound HTTP requests to Reports Developer endpoints until the patch is 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.
