Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations.

102 checks ran across 6 assessable dimensions. None found a significant problem; 3 raised something worth a question. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer.

plugins/ingestion-hive/src/main/java/org/opensearch/plugin/hive/metastore/ThriftHiveMetastore.java is 8,687 lines, 84× this codebase's median file

adequate

The median source file here is 103 lines. 101 files exceed 1,030 lines, the largest being 8,687. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

A note that does not affect this rating: measured against its own codebase's median, it is below the 85th percentile of 382 surveyed projects' largest files, where this check begins to count.

Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.

An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.

adequate

151 of 2119 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

87 files still carry code deprecated more than two years ago

adequate

87 files were marked deprecated over two years ago and still are, the oldest since Mar 2021. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Releases are cut from another branch than the one surveyed

adequate

The newest release, 3.9.0, is not on the branch this survey read; the newest pre-release on it is 3.0.0-alpha1. The shipped product may differ from what this report describes. Survey the release branch too. This was read from the most recent 50,000 commits (20 Nov 2014 to 23 Oct 2026) only; older history was not read.

Security & Reliability Posture

05.6

1 Dockerfile runs the application as root

adequate

No USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.

Evidence

05.27

The build runs third-party code it does not pin

adequate

4 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

05.21

3 shell commands built from strings

adequate

3 places run a command through a shell (`shell=True`, `os.system`, `exec` with a template) rather than passing arguments. Where any part comes from outside, it is command injection. Ask where each one's input comes from.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

11 advisories against this project in the last 24 months, 6 high or critical

adequate

The newest was published on 2026-10-22. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 11 of them are fixed in the code you ship could not be told from this history. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 12 records name OpenSearch with nothing tying them to this repository (CVE-2025-23671, CVE-2026-107335, CVE-2026-111906, …).

A note that does not affect this rating: it describes the project's advisory record, and no advisory in it is known to affect the surveyed commit.

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

06.9

No error reporter is wired in

adequate

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

5 checks against the running system follow from the findings above: what a buyer's engineer will try, how to run it first, and what to have ready. A paid survey of this repository includes them. See the tiers.

A paid survey of a public repository is also reviewed: a language model reads each finding against the code and withdraws only findings it judges the code contradicts, each listed with its reason. The review is a language model's reading of the findings against the code, and it can be wrong. It never adds a finding, never raises a band, and never removes a finding from a proven check or an advisory that affects the surveyed version.

What a person adds

The survey reads what the repository can show. The code cannot settle these questions, and on them this report states nothing. Each says where its answer lives: your own engineer, the company, or an assessor you choose can settle it. Questions marked measured open with something this repository shows.

  2. The bulk of this system sits in server/, modules/, plugins/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (distribution/docker/docker-compose.yml and 5 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2

A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.

Anyone can check this report against the authoritative record — click the stamp, or enter QVF4-J7E0-1XVF at borehole.dev/verify.

The code commits to the 106 checks this run performed, the bands they produced, and the commit they were read at. It does not cover checks written since.

Where this scan ran

This scan ran on ordinary cloud infrastructure (cloud-run), not in a hardware-isolated confidential VM. Nothing about it is attested by Google.

What an attested survey proves, and what it does not.

What this scan did with the repository — 7 steps

Written by the steps themselves as they ran, not described afterwards. A hand-written account of a data flow drifts the first time somebody changes the flow and not the account.

An automated reading of a repository's code and its history up to one commit, with public advisory records. It may be wrong, it is not legal, financial, investment or security advice, and it does not replace diligence by a qualified person. It is provided for information: nobody may rely on it (Borehole's terms, section 3).
