Vulnerability in the Helidon product of Oracle Fusion Middleware (component: Imperative Web Server). The supported version that is affected is 4.5.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Helidon. 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 and unauthorized ability to cause a partial denial of service (partial DOS) of Helidon. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L).
AnalysisAI
Unauthenticated remote exploitation of Oracle Helidon 4.5.3's Imperative Web Server component allows network attackers over HTTP to achieve partial confidentiality disclosure, data manipulation, and denial of service - with a confirmed scope change indicating the impact can extend to components beyond Helidon's own security boundary. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C) places this among the most easily reachable vulnerability classes: no credentials, no user interaction, and no elevated complexity required. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level HTTP access to a Helidon 4.5.3 instance running the Imperative Web Server component. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.3 score reflects a compound risk profile: while the individual CIA impacts are all Low (C:L/I:L/A:L), the fully unauthenticated network vector (AV:N/AC:L/PR:N/UI:N) combined with a scope change (S:C) materially elevates real-world risk beyond what partial-impact scores typically suggest. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker identifies a Helidon 4.5.3 Imperative Web Server exposed over HTTP - potentially via service discovery, Shodan-style scanning, or known deployment patterns in Oracle Fusion Middleware environments. The attacker sends a specially crafted HTTP request that triggers the underlying flaw, resulting in partial read access to application data, limited data manipulation, partial service disruption, and potential cascading impact on adjacent components due to the scope change. … |
| Remediation | Apply the patch or version upgrade specified in the Oracle Critical Security Patch Update for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html; Oracle CPUs include specific patch identifiers and minimum fix versions - the exact patched build must be confirmed from that advisory, as no fix version number was present in the available intelligence. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
