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

103 checks ran across 6 assessable dimensions. None found a significant problem; 4 raised something worth a question. 13 findings, each with evidence. One dimension cannot be assessed without an acquirer.

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

adequate

6 of 18 `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/custom-tokenizers.dockerfile docker/custom-tokenizers.dockerfile:1 — base image without a version

src/transformers/modeling_utils.py is 5,215 lines, 27× this codebase's median file

adequate

The median source file here is 193 lines. 78 files exceed 1,930 lines, the largest being 5,215. 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.

11 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.

19 advisories against this project in the last 24 months, 11 high or critical

adequate

The newest was published on 2026-09-01. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. CVE-2026-1839 (high), CVE-2025-3933 (moderate), CVE-2025-2099 (high) and 2 more 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: 12 records name transformers with nothing tying them to this repository (CVE-2024-21799, CVE-2025-14920, CVE-2025-14921, …).

05.3

9 dependencies float, and no lockfile is committed

adequate

Dependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.

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

The build runs third-party code it does not pin

adequate

8 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; 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.

18 outbound calls can wait forever

adequate

18 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.

17 deserialisers that can run code

adequate

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

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.

No error reporter is wired in

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

8 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.

  3. The repository carries deployment configuration (docker/transformers-all-latest-gpu/Dockerfile and 10 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?

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.

BOREHOLE READING NOT A CERTIFICATION 8T8P-P9EC-H5FA 2026-10-22 · 6B6792F BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter 8T8P-P9EC-H5FA 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.

[![Borehole reading, not a certification](https://borehole.dev/badge/huggingface/transformers/6b6792f.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/8T8PP9ECH5FA?via=badge)

Borehole reading 8T8P-P9EC-H5FA, not a certification

Quoted evidence

5 pieces of evidence on this report quote the repository directly. Four checks quote text: up to five TODO-style comments, up to four commit subjects, up to five unpinned dependency lines and one status line from the README's first screen, such as “no longer maintained”. In each case the text is the evidence, which is why it is kept by default.

This rewrites every stored reading of this repository, and every later reading, including a re-read, is stored without the quoted text. The facts we keep to re-read it still hold the lines, as the privacy notice says. The pointers stay.

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).
