Worth checking first

Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.

What this survey read. This commit may not be the product users run: The newest release, ray-2.59.0, is not on the branch this survey read; the newest release on it is ray-0.7.0. Read this report as describing that commit, not the release users run. Survey the release branch or tag as well.

2 base images float: no version, or `latest`

adequate

2 of 9 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence
docker/ray-llm/Dockerfile docker/ray-llm/Dockerfile:57 — base image without a version
docker/ray-llm/Dockerfile docker/ray-llm/Dockerfile:112 — base image without a version

python/ray/data/dataset.py is 8,940 lines, 70× this codebase's median file

adequate

The median source file here is 127 lines. 88 files exceed 1,270 lines, the largest being 8,940. 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.

38 files still carry code deprecated more than two years ago

adequate

38 files were marked deprecated over two years ago and still are, the oldest since Apr 2022. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

5 Dockerfiles run 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

44 locked dependencies have published vulnerabilities, 70 high or critical in what ships

adequate worth checking first

44 of 908 locked dependencies match 121 published advisories in OSV, 70 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version.

The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. Opening python/ray/dashboard/client/package-lock.json settles it. If it holds when someone checks it, this finding is significant.

Evidence

1 environment file is committed

adequate

python/ray/dashboard/client/.env.production.local is tracked in git. Environment files are where credentials usually live, and committing one usually means nobody decided how secrets reach the running application. Whatever is in it is in the history for good. Check 05.1 says whether it holds anything credential-shaped.

The build runs third-party code it does not pin

adequate

7 steps pipe a download straight into a shell. 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.

28 outbound calls can wait forever

adequate

28 HTTP calls use a client with no timeout (Python `requests` without `timeout=`, or Go's default client). When a dependency slows down, each one holds a worker until the connection gives up, and enough of them take the service down with the dependency.

6 advisories against this project in the last 24 months, 4 high or critical, 1 on CISA's known-exploited list

adequate

1 of them is on CISA's known-exploited list: check first whether the release you run has the fix. The newest was published on 2026-07-01. 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 1 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 0.7.0. Answer lives in: the release you run, set against each fixed version. GHSA-q279-jhrf-cc6v (critical), GHSA-hhrp-gw25-jr43 (high), GHSA-q5fh-2hc8-f6rq (moderate) are fixed in the surveyed commit; which release carries them cannot be told from this history, which does not place the release users run. Answer lives in: the version you run. The record is incomplete: NVD: 30 records name ray with nothing tying them to this repository (CVE-2002-2036, CVE-2004-0701, CVE-2006-4049, …).

Sends usage data to usage-stats.ray.io by default

Every installation reports to the vendor unless its operator turns this off. For a buyer running it inside their own product, that is an outbound data flow to a third party: ask what is sent, how often, and whether the buyer's customers were told.

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

Check it on the running system

11 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 python/, src/, release/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (docker/base-deps/Dockerfile and 8 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2
  4. What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

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.

Embed the badge

Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.

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.
