Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. Versions prior to both 4.10.16 and 3.10.5 do not correctly handle descending array index order during form-urlencoded body binding in theJsonBeanPropertyBinder::expandArrayToThreshold, which allows remote attackers to cause a DoS (non-terminating loop, CPU exhaustion, and OutOfMemoryError) via crafted indexed form parameters (e.g., authors[1].name followed by authors[0].name). This issue has been fixed in versions 4.10.16 and 3.10.5.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

  - Security-in-Depth issue in the Spatial and Graph (SQLite) component of Oracle Database Server. This     vulnerability cannot be exploited in the context of this product. (CVE-2025-6965)

  - Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are     19.3-19.30 and 21.3-21.21. Easily exploitable vulnerability allows unauthenticated attacker with network     access via Oracle Net to compromise Java VM. Successful attacks of this vulnerability can result in     unauthorized access to critical data or complete access to all Java VM accessible data. (CVE-2026-35229)

  - Vulnerability in the Clusterware (Micronaut) component of Oracle Database Server. Supported versions that     are affected are 19.3-19.30 and 23.4.0-23.26.1. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTP to compromise Clusterware (Micronaut). Successful attacks of this     vulnerability can result in unauthorized creation, deletion or modification access to critical data or all     Clusterware (Micronaut) accessible data. (CVE-2026-33013, CVE-2026-33870)

  - Vulnerability in the RDBMS (OpenSSL) component of Oracle Database Server. Supported versions that are     affected are 19.3-19.30 and 23.4.0-23.26.1. Easily exploitable vulnerability allows high privileged     attacker having None privilege with network access via multiple protocols to compromise RDBMS (OpenSSL).
    Successful attacks of this vulnerability can result in takeover of RDBMS (OpenSSL). (CVE-2026-31790)

  - Vulnerability in the RDBMS (Python) component of Oracle Database Server. Supported versions that are     affected are 21.3-21.21 and 23.4.0-23.26.1. Easily exploitable vulnerability allows unauthenticated     attacker with network access via multiple protocols to compromise RDBMS (Python). Successful attacks     require human interaction from a person other than the attacker. Successful attacks of this vulnerability     can result in unauthorized access to critical data or complete access to all RDBMS (Python) accessible     data. (CVE-2026-26007)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
