Lifecycle Timeline
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 require human interaction from a person other than the attacker and while the vulnerability is in Helidon, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Helidon accessible data as well as unauthorized read access to a subset of Helidon accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
AnalysisAI
Unauthorized read and write access to Helidon-accessible data is possible through the Imperative Web Server component in Oracle Helidon 3.2.19 via a network-deliverable HTTP attack that requires victim interaction. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) with scope change is characteristic of a client-side injection vulnerability such as Cross-Site Scripting or CSRF, where the attack crosses a scope boundary to impact resources or systems beyond the Helidon process itself. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires Oracle Helidon 3.2.19 with the Imperative Web Server component exposed over HTTP and reachable by the attacker over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.1 (Medium) is consistent with a bounded-impact client-side vulnerability: low complexity and no privilege requirement lower the exploitation barrier, but mandatory user interaction (UI:R) prevents fully automated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Oracle has addressed this vulnerability as part of its Critical Patch Update for August 2026; consult the advisory at https://www.oracle.com/security-alerts/cspuaug2026.html for the exact patched release of Helidon - a precise fixed version number is not available in the current data and should not be assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
