Nothing significant. Questions worth asking about Security & Reliability Posture, Architecture & Codebase — including AI provenance.

67 checks ran across 6 assessable dimensions. 2 findings are worth checking first. 13 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.

  • 05.20 5 SQL statements built from strings
  • 05.26 4 locked dependencies have published vulnerabilities, 5 high or critical
Degraded run. apache/superset is about 1,154 MB, over the 500 MB free-tier limit, so only the most recent 5,000 commits were read. Signals needing full history are reported as inconclusive rather than clean. Full depth is available on the Report tier.
An earlier reading. A newer reading of this repository exists. This one is kept because its verification code attests to it. Read the newest.
Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
  • 1 finding that needed more history than this survey read is no longer published.
  • 2 findings rated significant by a check that has not yet held up in Borehole's calibration are now worth checking first.
  • 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.

confidence: moderate
  • 75% of non-merge commits carry any trailer at all
  • no widespread author/committer date divergence
  • the declared share is neither decisive nor negligible, so the true figure is more sensitive to undeclared work
325,009 lines excluded as lockfiles, vendored or generated.
This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

superset/security/manager.py is 6,398 lines, 60× this codebase's median file

adequate

The median source file here is 105 lines. 70 files exceed 1,050 lines, the largest being 6,398. 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.

Tests are retried until they pass

adequate

The suite is configured to retry failing tests (superset-frontend/playwright.config.ts). A retry turns a flaky test green without saying why it failed, so a green build means the tests passed eventually. Ask how many retries a typical run needs, and which tests need them.

Evidence

140 direct dependencies in a single manifest

adequate

superset-frontend/package.json declares 140 direct dependencies. Each one is a maintenance obligation, a supply-chain surface and a potential licence question that transfers with the asset. The count says nothing about whether any given dependency was a good choice; it says how many such choices a buyer inherits.

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
no-USER-instruction .devcontainer/Dockerfile — runs as root

05.25

1 environment file is committed

adequate

docker/.env 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.

Evidence
docker/.env docker/.env — committed environment file

05.27

The build runs third-party code it does not pin

adequate

4 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.

Evidence
.devcontainer/Dockerfile .devcontainer/Dockerfile:16 — download piped into a shell

05.17

99 of 400 migrations cannot be rolled back

adequate

99 schema migrations (25%) have no working way back: an empty `downgrade`, a `down` that does nothing, or a data migration with no reverse. A bad deploy that includes one is recovered from a backup, not reverted. Ask when a restore was last rehearsed.

5 SQL statements built from strings

adequate worth checking first

5 places in product code build SQL by formatting or joining strings rather than passing parameters. Where any part of the string comes from a request, it is an injection point. Each site needs a look; the fix, parameters, is small.

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 superset/db_engine_specs/snowflake.py:548 and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence
superset/db_engine_specs/snowflake.py superset/db_engine_specs/snowflake.py:548 — SQL built from a string
superset/utils/encrypt.py superset/utils/encrypt.py:369 — SQL built from a string

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.

Evidence
RELEASING/changelog.py RELEASING/changelog.py:274 — command run through a shell

05.22

3 deserialisers that can run code

adequate

3 places read data with a deserialiser that executes what it reads (pickle, `yaml.load` without a safe loader, object streams, `unserialize`). That is safe on data the system wrote itself and remote code execution on anything else. Ask where each one's input comes from.

05.26

4 locked dependencies have published vulnerabilities, 5 high or critical

adequate worth checking first

4 of 1,859 locked dependencies match 6 published advisories in OSV, 5 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 superset-frontend/cypress-base/package-lock.json and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

2 vendored components with no licence

adequate

Third-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

Evidence

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

7 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.

Anyone can check this report against the authoritative record — click the stamp, or enter YNQ4-H28Z-ZYTH at borehole.dev/verify.

The code commits to the 68 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 — 6 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.
