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.

05.26 101 locked dependencies have published vulnerabilities, 116 high or critical in what ships

Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.

4 findings from checks Borehole's calibration found wrong more often than right are no longer published.

client/static/fancytree/jquery.fancytree-all.js is 9,227 lines, 139× this codebase's median file

adequate

The median source file here is 66 lines. 8 files exceed 1,000 lines, the largest being 9,227. 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. Measured against its own codebase's median, it is larger than 85% of 382 surveyed projects' largest files.

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.

01.15

55 errors caught and discarded in product code

adequate

55 places catch an error and do nothing with it, across 7 files (0.7 per thousand lines). Each is a failure the system will not report. They surface later as problems nobody can explain, and they are cheap to fix now.

02.3

Tests cover a thin slice of the codebase

adequate

16 test files against 346 source files (4.6%). This does not measure whether the tests are good, only whether enough of them exist for the codebase to be changed safely by someone who did not write it — which is exactly the situation after an acquisition.

1 committed .only switches other tests off

adequate

1 test file commits a focused `.only`, which runs that test and silently skips the rest of its suite. 1 skip markers across 1 of 22 test files. Each is a failure somebody chose to stop seeing; the question is whether anyone is tracking them.

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 — none are present. 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.

03.5

The contributor who wrote a quarter or more of this has not committed here for more than three years

adequate

One person authored a quarter or more of 1,133 commits and has not committed here for more than three years, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

Node.js 10 is past end of life

adequate

The code is pinned to Node.js 10 (end of life 2021-04-30). None of these receives security fixes any more; the first stopped on 2021-04-30. 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.

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

Security & Reliability Posture

05 · adequate · ratings ↑

05.2

None of the standard security guard rails are configured

adequate

There is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.

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

101 locked dependencies have published vulnerabilities, 116 high or critical in what ships

adequate worth checking first

101 of 1,580 locked dependencies match 208 published advisories in OSV, 116 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 server/package-lock.json settles it. If it holds when someone checks it, this finding is significant.

Evidence

server/package-lock.json	`server/package-lock.json` — babel-traverse 6.26.0: GHSA-67hx-6x53-jw92 (critical)

34 places insert HTML from a variable without sanitising it

adequate

34 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.

Relicensed: GPL-3.0 → MIT (2016-09-15) → EUPL-1.1 (2017-02-17) → GPL-3.0 (2017-03-02)

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.

A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

05.65

1 advisory against this project in the last 24 months, 1 high or critical

adequate

The newest was published on 2021-02-19. 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 2.20210609.0. Answer lives in: the release you run, set against each fixed version.

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.

06.2

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.

1 of 4 deployed images carry no version, or `latest`

adequate

1 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.

07 · not assessable · ratings ↑

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

Check it on the running system

10 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.

Could not conclude, or did not apply — 28

Not a clean result. Each says why it could not answer here.

Signal	Why
04.fixes_with_tests	too few fixes in 24 months to judge
04.fix_share_trend	fewer than six busy quarters to compare
04.schema_churn	columns, once added, stay
06.telemetry_depth	none at all is 06.1
06.print_logging	a frontend: console output is the browser's, not the server's
06.alert_rules	no alert rules in the repository; they may live in a console
06.probes_identical	no Kubernetes probes
06.single_replica	no Kubernetes deployments
06.release_markers	fewer than 100 commits in the last year
06.feature_flags	no feature-flag service; flags may live elsewhere
03.second_contributor_attrition	the repository itself is quiet
03.bus_factor_trend	fewer than three active years to compare
02.ci_runs_tests	no CI configuration to read
02.ci_test_gating	no CI configuration to read
02.revert_share	too few recent commits to judge how often change is undone
02.lint_in_build	too small, or no CI to wire a linter into (02.2)
02.commit_size	too few recent commits
01.notebook_outputs	not a data or machine-learning repository
05.supply_chain_pinning	no CI actions or pipe-to-shell installs to check
05.outbound_timeouts	not assessed for JavaScript, the language the product is written in: this check's patterns read other languages only
05.resource_limits	no Kubernetes workload manifests
05.cleartext_traffic	not a mobile app
05.dataset_provenance	not a data or machine-learning repository
05.license_manifest_conflict	no packaging manifest states a licence
04.flags_accumulating	few or no feature flags in the history
04.api_versions_coexisting	one API version is served, or none
04.ci_platforms_dropped	no platform was dropped from CI in the last two years
05.project_advisories	could not tell whether 1 published advisory affects the surveyed code: its version could not be placed

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).
