1DescriptionCVE.org
Vulnerability in the Helidon product of Oracle Fusion Middleware (component: Imperative Web Server). The supported version that is affected is 3.2.19. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Helidon. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Helidon accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
AnalysisAI
Unauthorized data read in Oracle Helidon 3.2.19's Imperative Web Server component allows unauthenticated remote attackers to access a subset of protected application data via HTTP. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivial network-level exploitation with no credentials or user interaction required, consistent with the intelligence tag of Authentication Bypass. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level HTTP access to a deployment of Oracle Helidon 3.2.19 using the Imperative Web Server (Helidon SE) component - not Helidon MP. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 Medium score captures a real but bounded risk: network-reachable, zero-prerequisite exploitation lowers the barrier to attempt considerably, but C:L impact limits the damage to a partial data exposure rather than full system compromise or availability loss. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker with HTTP access to a Helidon 3.2.19 Imperative Web Server sends a crafted or standard HTTP request to an endpoint that should require authorization, exploiting the authentication bypass to receive a response containing protected data. Because the CVSS vector indicates AC:L with no user interaction, the attacker requires no special tooling beyond a basic HTTP client. … |
| Remediation | Apply Oracle's August 2026 Critical Patch Update as documented at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
