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

101 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 16 findings, each with evidence. One dimension cannot be assessed without an acquirer.

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.

  • 05.26 91 locked dependencies have published vulnerabilities, 4 high or critical in what ships
What this survey read. This commit may not be the product users run: The newest release, v1.6.0, is not on the branch this survey read; the newest pre-release on it is v1.2.0-rc.1. Read this report as describing that commit, not the release users run. Survey the release branch or tag as well.
Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 5 findings from checks Borehole's calibration found wrong more often than right are no longer published.

front/lib/internal_api/billing.pb.ex is 1,960 lines, 32× this codebase's median file

adequate

The median source file here is 61 lines. 45 files exceed 1,000 lines, the largest being 1,960. 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.

Node.js 16 is past end of life

adequate

The code is pinned to Node.js 16 (end of life 2023-09-11). None of these receives security fixes any more; the first stopped on 2023-09-11. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

05.1

1 credential-shaped string in the tree sit in tests, examples, documentation or local development settings

adequate

Strings shaped like credentials appear only where fakes are usual: test fixtures, examples, documentation, placeholders and local stacks. They are almost always fakes. Ask someone to confirm that none of them works anywhere, because a real key in a development file is still a real key. 4 other matchs set aside: expired tokens, licence tokens a vendor verifies with a public key, or placeholder text where a key would go. None grants access to anything.

05.6

7 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

05.26

91 locked dependencies have published vulnerabilities, 4 high or critical in what ships

adequate worth checking first

91 of 1,206 locked dependencies match 202 published advisories in OSV, 90 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. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

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 auth/mix.lock and the 2 other files it cites settles it. If it holds when someone checks it, this finding is significant.

05.25

2 environment files are committed

adequate

front/env/.env.internal-apis, github_hooks/.env are 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.

05.13

3 outbound calls can wait forever

adequate

3 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.

32 places insert HTML from a variable without sanitising it

adequate

32 places set HTML from a value that is neither a literal nor passed through a sanitiser. Where the value can come from a user, that is stored cross-site scripting, and it is the first thing a buyer's security review looks for in a frontend.

Has a reporting host, telemetry.semaphore.io; its default could not be read

adequate

bootstrapper/pkg/installation/installation.go names telemetry.semaphore.io as a place to report to, and no setting read here shows whether reporting is on as shipped. For a buyer running it inside their own product, ask whether copies report by default, what is sent, how often, and whether the buyer's customers were told.

06.14

Readiness and liveness probes are identical in 9 of 40 workloads

adequate

Both probes call the same endpoint. When a dependency slows down, the liveness probe fails with the readiness probe, so the platform restarts pods that only needed taking out of rotation, and a partial outage becomes a full one. Liveness should ask whether the process is alive; readiness whether it can serve.

An error reporter is installed but never initialised

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.

36 of 36 deployed images carry no version, or `latest`

adequate

36 images in the deployment configuration are named without a version or as `latest`. A redeploy can change the software without a commit, a rollback has nothing to roll back to, and nobody can say from the repository what is running.

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

Check it on the running system

12 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.

BOREHOLE READING NOT A CERTIFICATION VD5W-ZC8K-BPY1 2026-11-07 · A5B3F7F BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter VD5W-ZC8K-BPY1 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.

Put the mark in your README

The image is wrapped in a link to the verification page, so a reader can check it rather than take it on trust. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

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).
