Trace File Analyzer CVE-2026-70715

The mandatory prerequisite is physical or logical network adjacency to the host running Oracle Autonomous Health Framework - the attacker must be on the same LAN segment, VLAN, or cluster interconnect network as the AHF host; internet-based or fully remote exploitation is not possible per the AV:A CVSS metric. The Trace File Analyzer sub-component must be running, which is typical by default in AHF deployments. No authentication is required and no special non-default configuration is needed for the vulnerable versions (26-26.1.0, 26.2.0, 26.3.1, 26.5.0, 26.5.2). The primary limiting factor beyond adjacency is deployment context: AHF is primarily deployed on Oracle Engineered Systems (Exadata, Oracle Database Appliance) and similar enterprise database infrastructure, meaning the adjacent network segments are typically enterprise-managed and not directly accessible to external parties without a prior compromise.

The CVSS 3.1 score of 8.8 (High) is appropriately driven by the full CIA:H impact and absence of required authentication, but the AV:A vector meaningfully constrains the attacker pool to those with physical or logical adjacency - a significant real-world limiter compared to AV:N vulnerabilities. In typical AHF deployments on Exadata or ODA, the management and cluster-interconnect networks may be accessible to multiple privileged users and infrastructure components, making the adjacent-network bar achievable for insiders, compromised infrastructure hosts, or attackers who have already pivoted into an internal segment. No EPSS score was provided in the input data, preventing a probabilistic exploitation estimate. The absence of a CISA KEV listing and no identified POC code suggests exploitation has not been observed at mass scale; however, the AC:L rating means no special conditions are needed once adjacency is achieved, so exploitation difficulty is low for a positioned attacker. The 'Information Disclosure' tag in the source data understates the actual CVSS-confirmed impact of full system takeover - this discrepancy should be noted but the CVSS vector from Oracle's own advisory is the authoritative signal. The missing CWE assignment is a data gap that limits root-cause confidence and patch verification.

An attacker with a foothold on the same management LAN or cluster interconnect VLAN as an Oracle AHF host - achieved via a compromised admin workstation, a rogue device plugged into the segment, or prior lateral movement - sends a crafted unauthenticated request to the Trace File Analyzer service. Because attack complexity is rated low, no race condition or environmental preparation is required beyond network adjacency, and the attacker achieves full control of the AHF instance. No public proof-of-concept has been identified at time of analysis.
