Executive Summary
ArcadeDB versions before 26.8.1 fail to sanitize database names in the POST /api/v1/server endpoint's create database and drop database commands, allowing authenticated root users to write and delete arbitrary files outside the configured database directory. Attackers can supply database names containing ../ sequences to create databases at arbitrary filesystem paths or recursively delete directories the server process can access. CVSS Score: 8.7 CWE: CWE-22
Decision: Validate relevance and exposure using the cited source and internal evidence before treating this record as an incident, confirmed compromise, or customer-specific finding.

KEV catalog check: Not present in the successfully retrieved catalog snapshot; this does not prove absence of exploitation.
Technical Analysis
Vulnerability class: Path Traversal. Assessment: Active exploitation is not confirmed by the available evidence. Prioritization must combine technical severity, exposure, asset criticality, and compensating controls.
Exposure and Remediation Decisions
P0 — Inventory: Confirm the affected product and version against authoritative vendor/NVD data; prioritize internet-facing and business-critical assets.
P0 — Remediation: Availability not established in the source record — verify vendor guidance
P1 — Compensating controls: Restrict exposure, enforce least privilege, and apply vendor-supported mitigations when immediate remediation is not possible.
P1 — Retrospective review: Search only the telemetry relevant to the affected component and validated vulnerability class; absence of alerts does not prove absence of exploitation.

MITRE ATT&CK Mapping
Initial Access → Exploit Public-Facing Application (T1190), conditional on an exposed web application.
Mappings are conditional analytical aids, not claims that the technique occurred. Promote a mapping to observed only after telemetry confirms the behavior.
Detection Engineering
DETECTION STATUS: SYNTAX_VALIDATED_EXPERIMENTAL
The source identifies a request-oriented vulnerability class with testable class-level request indicators.
Collect decoded request target, destination/upstream address, response status, and application error telemetry.
Treat matches as investigation leads; confirm product route and affected version before escalation.

Role-Based Decisions
Vulnerability Manager: Track against cve vulnerability advisory intake at severity commensurate with not confirmed by available evidence; not in verified kev snapshot. — Prioritization reflects this record's own exploitation/patch evidence, not a fixed severity template.
Soc Manager: Review the detection guidance below before enabling any blocking action on it. — Detection maturity for this record is stated explicitly, not assumed production-ready.
Source Reliability & Corroboration
nvd: A/B — Reliable (completely or usually reliable source)
Whether an independent second source corroborates this record has not been assessed (see the evidence ledger). This report does not wait on that assessment to publish, and does not overstate certainty in the meantime.
