CVE-2026-70731 in Autonomous Health Framework
Summary
by MITRE • 08/19/2026
Vulnerability in Oracle Autonomous Health Framework (component: Trace File Analyzer). Supported versions that are affected are 26-26.1.0, 26.2.0, 26.3.1, 26.5.0 and 26.5.2. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Autonomous Health Framework executes to compromise Oracle Autonomous Health Framework. While the vulnerability is in Oracle Autonomous Health Framework, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Autonomous Health Framework accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Autonomous Health Framework. CVSS 3.1 Base Score 8.4 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H).

The Oracle Autonomous Health Framework, specifically within its Trace File Analyzer component, contains a critical security flaw that allows for the compromise of system integrity and availability when exploited by an attacker with low privileges. This vulnerability affects several supported versions including 26-26.1.0, 26.2.0, 26.3.1, 26.5.0, and 26.5.2. The core issue stems from insufficient validation or handling of inputs within the Trace File Analyzer module, which is responsible for processing diagnostic trace data generated by Oracle database instances. Because this component operates with elevated privileges to perform health checks and diagnostics, a flaw in its logic can be leveraged to escalate privileges or disrupt critical operations even when the initial attacker has only low-level access credentials on the infrastructure hosting the framework.
From a technical perspective, the vulnerability enables an authenticated user who is not typically granted administrative rights to manipulate how trace files are processed. This could involve injecting malformed data into log streams or triggering specific parsing routines that lead to memory corruption, buffer overflows, or logic errors within the application layer. The presence of such flaws in diagnostic tools is particularly dangerous because these components often run with high-level system permissions to ensure they can access necessary logs and performance metrics. An attacker exploiting this flaw does not need complex user interaction, as indicated by the User Interaction parameter being set to None in the CVSS vector, allowing for automated or scripted exploitation once initial low-privileged access is established on the host machine.
The operational impact of successfully exploiting this vulnerability is severe, characterized primarily by high impacts on both integrity and availability while having no direct effect on confidentiality according to the provided CVSS 3.1 metrics. The attacker gains the ability to create, delete, or modify critical data accessible to Oracle Autonomous Health Framework. This compromises the integrity of diagnostic records and potentially other system configurations managed by the framework. Furthermore, the vulnerability allows for causing a hang or a frequently repeatable crash, leading to a complete denial of service condition. Since the Trace File Analyzer is integral to maintaining the health monitoring capabilities of the environment, its failure can blind administrators to actual underlying database issues, effectively masking further malicious activities or system degradation.
This incident represents a significant scope change risk where compromising one component leads to broader ecosystem instability. Although the vulnerability resides in Oracle Autonomous Health Framework, the resulting denial of service and data manipulation can significantly impact additional products that rely on this framework for operational continuity. The CVSS vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H) highlights an Attack Vector of Local, low Complexity, requiring Low Privileges, with no User Interaction required, and a Scope Change indicating that the vulnerability affects resources beyond its own security scope. This classification underscores the critical nature of securing even auxiliary management tools within enterprise environments.
To mitigate this risk, organizations must apply the latest available patches or updates provided by Oracle for all affected versions of the Autonomous Health Framework. It is imperative to verify which specific version is deployed in each environment and prioritize patching systems where low-privileged accounts have access to the underlying infrastructure. Additionally, implementing strict network segmentation can limit lateral movement opportunities if an attacker gains initial foothold on a host running this component. Monitoring for unusual activity within trace file processing logs or unexpected crashes of health framework services should be integrated into existing security monitoring strategies. Regular audits of user privileges ensuring that diagnostic tools are only accessible to necessary administrative personnel will also reduce the attack surface associated with low-privileged account exploitation.
