Nothing significant. Questions worth asking about Security & Reliability Posture, Engineering Process & SDLC Maturity.

102 checks ran across 6 assessable dimensions. 2 findings are worth checking first. 12 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.

  • 02.1 Change lands on the trunk with no trace of review
What this survey read. This commit may not be the product users run: the product's code is in submodules this survey did not read (test-e2e/features/, connectors/cache/redis/, connectors/cache/memcached/), beside 100 source files of its own. No dimension is rated strong: most of the product was not read. Survey the submodules' repositories 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.
  • 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.
  • 3 findings about one contributor are withheld: one author wrote nearly all of this repository's commits; a buyer of this report reads them.

02.1

Change lands on the trunk with no trace of review

adequate worth checking first

In the last 24 months, 1 of 51 commits (2.0%) carry any trace of review: a merge, a pull-request reference, a Reviewed-by or Reviewed-on trailer, a Closes/Fixes reference, a maintainer's sign-off on someone else's change, or a change applied by someone other than its author. Every common review workflow leaves at least one of those, so either review happens somewhere this history cannot see, or it is not happening. A buyer should establish which before relying on the review story they are told.

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. If it holds when someone checks it, this finding is significant.

Evidence

02.6

Almost no process scaffolding exists in the repository

adequate

Of five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: CI workflows. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.

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

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

05.26

12 locked dependencies have published vulnerabilities, 8 high or critical in what ships

adequate worth checking first

12 of 194 locked dependencies match 23 published advisories in OSV, 8 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 telemetry-server/package-lock.json and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Notes that do not affect this rating
05.27

The build runs third-party code it does not pin

adequate

7 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; 2 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.

05.20

1 SQL statement built from strings

adequate

1 places in product code build SQL by formatting or joining strings rather than passing parameters. In each, what the code shows going in is a table or column name, a constant, or something the line does not show, not a request's value. Ask whether any value reaches these strings, rather than a parameter.

4 shell commands built from strings

adequate

4 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.

Relicensed: MIT → Apache-2.0 (2016-06-30) → AGPL-3.0 (2016-07-09) → MIT (2019-10-26)

adequate

The root licence changed 3 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.

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

No telemetry or error reporting is wired in anywhere

adequate

None of 247 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

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

9 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.

Not rated: structurally not assessable from a repository.

  1. This is primarily a TypeScript codebase. Does your engineering organisation already run TypeScript in production, or would this be the first? 07.1
  2. The bulk of this system sits in src/, bin/, conf/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (Dockerfile and 1 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?

Anyone can check this report against the authoritative record — click the stamp, or enter 8Y7V-GDPC-NH96 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).
