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

103 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
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.

1 base image floats: no version, or `latest`

adequate

1 of 36 `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/mini/Dockerfile docker/mini/Dockerfile:15 — base image without a version

go/mysql/collations/charset/simplifiedchinese/tables.go is 43,998 lines, 354× this codebase's median file

adequate

The median source file here is 124 lines. 70 files exceed 1,240 lines, the largest being 43,998. 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 97% of 382 surveyed projects' largest files.

94 direct dependencies in a single manifest

adequate

go.mod declares 94 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.

5 files still carry code deprecated more than two years ago

adequate

5 files were marked deprecated over two years ago and still are, the oldest since Nov 2022. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

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

13 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
no-USER-instruction docker/binaries/logrotate/Dockerfile — runs as root
no-USER-instruction docker/binaries/logtail/Dockerfile — runs as root

10 SQL statements built from strings

adequate worth checking first

10 places in product code build SQL by formatting or joining strings rather than passing parameters, and in 5 of them a value, not a table or column name, goes into the string. Where any of those values 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 go/vt/vtctl/workflow/stream_migrator.go:474 and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence
go/vt/vtctl/workflow/stream_migrator.go go/vt/vtctl/workflow/stream_migrator.go:474 — SQL built from a string
go/vt/vtctl/workflow/stream_migrator.go go/vt/vtctl/workflow/stream_migrator.go:579 — SQL built from a string

The build runs third-party code it does not pin

adequate

1 step pipes 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.

A note that does not affect this rating: notes like it are common in well-run projects.

05.13

11 outbound calls can wait forever

adequate

11 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.

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

Evidence

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

adequate

The newest was published on 2026-10-13. 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 2 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 10.0.2. Answer lives in: the release you run, set against each fixed version. GHSA-m282-7w35-g77m (high), GHSA-9248-hccp-qf8f (high), GHSA-9rx3-8pwm-c228 (high) and 12 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.

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.

Evidence
GHSA-92cc-q2h6-m2vr 2026-10-13: GHSA-92cc-q2h6-m2vr (high), fixed in 23.0.8: Vitess is vulnerable to SQL injection via convert_tz() arguments in a VStream filter written into the copy-phase snapshot query
GHSA-m282-7w35-g77m 2026-10-13: GHSA-m282-7w35-g77m (high), fixed in 23.0.8: Vitess is vulnerable to SQL injection via an unvalidated global SET variable name re-emitted into a VTTablet validation query
GHSA-9248-hccp-qf8f 2026-10-13: GHSA-9248-hccp-qf8f (high), fixed in 23.0.8: Vitess is vulnerable to SQL injection via AST re-serialization of DATE, TIME and TIMESTAMP literals in SET system-variable statements
GHSA-9rx3-8pwm-c228 2026-10-13: GHSA-9rx3-8pwm-c228 (high), fixed in 23.0.8: Vitess is vulnerable to SQL injection via a session system variable value that breaks out of the SET_VAR optimizer-hint comment
GHSA-pfg5-ppc7-ff45 2026-10-13: GHSA-pfg5-ppc7-ff45 (high), fixed in 23.0.8: Vitess is vulnerable to SQL injection via trailing-comment splitting that hides SQL from parsing, planning and ACL checks

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

Check it on the running system

3 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 KB5M-QE88-0GHZ 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.

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).
