Impact
The Oracle Helidon product contains a vulnerability in the LRA component that permits an unauthenticated network attacker with HTTP access to read a subset of data exposed by Helidon. No privileges or additional authentication are required, and the flaw can expose confidential information without altering Helidon functionality or creating denial of service.
Affected Systems
Affected hosts run Oracle Helidon versions 4.0.0 through 4.5.5. These versions are supported by Oracle Fusion Middleware and are listed as vulnerable in the Oracle security alert for October 2026.
Risk and Exploitability
The CVSS v3.1 base score is 3.7, indicating a low severity attack mainly impacting confidentiality. The EPSS score is unavailable, and the vulnerability is not in the CISA KEV catalog, suggesting limited known exploitation. The attack vector is remote over HTTP, requiring no authentication or elevated privileges, so any host exposed to the public or lateral network can be compromised to read Helidon data.
