AI Analysis

Impact

Easily exploitable vulnerability within Oracle JDeveloper’s Security Framework component permits an unauthenticated attacker with network access to send requests that bypass normal authentication checks. The flaw requires the attacker to trigger a request that involves user interaction, such as opening a malicious link or interface. If successfully exploited, the attacker could view or download confidential data or obtain full access to all JDeveloper‑accessible information. This weakness corresponds to open redirect (CWE‑601) issues.

Affected Systems

The affected vendor is Oracle Corporation; the product is Oracle JDeveloper. Affected variants are versions 12.2.1.4.0 and 14.1.2.0.0. No other variants or earlier releases are listed in the CNA data.

Risk and Exploitability

The CVSS v3.1 Base score of 6.5 indicates moderate severity with confidentiality as the primary impact. The vector shows an attack available over the Internet via HTTP, requiring no special privileges but needing user interaction. The EPSS score of <1% suggests a very low probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog, meaning no known active exploits exist. Despite this low exploitation likelihood, the potential for unauthorized data exposure warrants timely mitigation.

OpenCVE Recommended Actions

  • Apply the latest Oracle patch or upgrade Oracle JDeveloper to a version that addresses the Security Framework flaw identified in CVE-2026-91318
  • Limit external HTTP access to the JDeveloper environment by configuring firewall rules or placing the application behind a VPN, ensuring only trusted networks can reach it
  • Review and tighten access control policies on the JDeveloper services, guaranteeing that only authorized users can access confidential data and that authentication is enforced for all endpoints
  • Monitor user activity for suspicious HTTP requests linked to the JDeveloper application and maintain logs to detect possible exploitation attempts
