Oracle AHF EUVD-2026-105893

Attacker must have an authenticated low-privilege local logon (PR:L, AV:L) to the host/infrastructure where Oracle Autonomous Health Framework and its Trace File Analyzer component execute - this is not remotely exploitable and requires no victim interaction (UI:N). The key limiting factors are: (1) local access to the Oracle DB/Grid Infrastructure server is mandatory, so exposure is confined to users who already have accounts or a foothold on that host; (2) the affected AHF versions must be in the 26.3-26.8 range; and (3) risk concentrates on shared or multi-tenant hosts where untrusted low-privilege local principals exist. On single-administrator, tightly controlled hosts the realistic risk is substantially lower.

This is a genuinely high-severity local privilege/compromise issue (CVSS 3.1 7.8) but NOT an internet-facing emergency. The CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) confirms exploitation requires local logon access to the host where Oracle Autonomous Health Framework executes, with low-level privileges already held - this is the single most important risk-limiting factor and sharply reduces the attack surface compared to a remote vulnerability. The high complexity-free (AC:L) and no-interaction (UI:N) profile means that ONCE an attacker has a foothold, escalation to full product takeover (C:H/I:H/A:H) is reliable. On the exploitation-likelihood axis the signals are weak: no EPSS score, no CISA KEV listing, and no public POC were provided, so there is no public exploit identified at time of analysis and no evidence of active exploitation. The practical read: prioritize patching on multi-user or shared Oracle database/Grid Infrastructure hosts where untrusted low-privilege local accounts exist, but treat it below any network-exploitable critical. NOTE A CONFLICT: the input Tags label this 'Information Disclosure,' yet the CVSS vector and description describe full takeover (C/I/A all High) - the tag understates the true impact and should not be relied upon for triage.

A low-privileged local user (or an attacker who has already gained an initial foothold via another vector) on an Oracle database/Grid Infrastructure host that runs Autonomous Health Framework abuses the Trace File Analyzer component to escalate and fully compromise AHF, which typically runs with elevated privileges. No user interaction is required and attack complexity is low, making exploitation reliable once local access exists. No public exploit code was identified at time of analysis.
