usebruno/bruno: technical due diligence, read from its repository
What Borehole read in usebruno/bruno's code and history at b13fe92: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongpackages/bruno-app/src/providers/ReduxStore/slices/collections/index.js is 4,532 lines, 50× this codebase's median file
adequateThe median source file here is 89 lines. 30 files exceed 1,000 lines, the largest being 4,532. 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.
packages/bruno-app/src/providers/ReduxStore/slices/collections/index.js:1 — 4,532 lines (50× median) |
packages/bruno-app/src/providers/ReduxStore/slices/collections/actions.js:1 — 3,864 lines (43× median) |
packages/bruno-app/public/static/diff2Html.js:1 — 3,214 lines (36× median) |

Engineering Process & SDLC Maturity
strongTests are retried until they pass
adequateThe suite is configured to retry failing tests (packages/bruno-cli/tests/integration/run-typed-persistence.spec.js). 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.
packages/bruno-cli/tests/integration/run-typed-persistence.spec.js:33 — test retry |
Product & Engineering Maturity
adequate103 direct dependencies in a single manifest
adequatepackages/bruno-app/package.json declares 103 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.
packages/bruno-app/package.json — 103 declared |
packages/bruno-electron/package.json — 56 declared |
packages/bruno-cli/package.json — 26 declared |
packages/bruno-js/package.json — 25 declared |
Releases are cut from another branch than the one surveyed
adequateThe newest release, v4.3.0, is not on the branch this survey read; the newest release on it is v3.0.1. The shipped product may differ from what this report describes. Survey the release branch too.
| tag v4.3.0 |
Security & Reliability Posture
adequate9 credential-shaped strings in the tree sit in tests, examples, documentation or local development settings
adequateStrings shaped like credentials appear only where fakes are usual: test fixtures, examples, documentation, placeholders and local stacks. They are almost always fakes. Ask someone to confirm that none of them works anywhere, because a real key in a development file is still a real key.
| 2 cited: GitHub token, where fakes are usual |
| 3 cited: private key block, where fakes are usual |
1 environment file is committed
adequatepackages/bruno-app/.env.production 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.
packages/bruno-app/.env.production — committed environment file |
The build runs third-party code it does not pin
adequate4 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. 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.
.github/workflows/npm-bru-cli.yml:47 — action pinned by tag |
.github/workflows/tests-linux.yml:50 — action pinned by tag |
44 locked dependencies have published vulnerabilities, 72 high or critical in what ships
adequate44 of 1,221 locked dependencies match 121 published advisories in OSV, 72 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.
package-lock.json — dompurify 3.4.14: GHSA-cg2g-xh64-v4q7 (critical), fixed in 3.4.17 |
package-lock.json — proxy-addr 2.0.7: GHSA-jqcg-44mw-7w3h (critical), fixed in 2.0.8 |
package-lock.json — shell-quote 1.10.0: GHSA-pqg4-j6r4-53mv (critical), fixed in 1.11.0 |
16 places insert HTML from a variable without sanitising it
adequate16 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.
packages/bruno-app/src/components/AiChatSidebar/index.js:765 — HTML from a variable |
packages/bruno-app/src/components/OpenAPISyncTab/SpecDiffModal/DiffRow.js:27 — HTML from a variable |
packages/bruno-app/src/components/SetAsVariablePopover/index.js:38 — HTML from a variable |
The production build publishes source maps
adequateThe build configuration emits source maps for production, so the original source, with its comments and structure, is downloadable by every visitor. Upload them to an error tracker and keep them off the public server instead.
packages/bruno-common/rollup.config.js:19 — source maps in a production build |
packages/bruno-converters/rollup.config.js:42 — source maps in a production build |
packages/bruno-filestore/rollup.config.js:53 — source maps in a production build |
Relicensed: MIT → BUSL-1.1 (2022-01-01) → MIT (2022-01-05)
adequateThe root licence changed 2 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, 5 high or critical
adequateThe newest was published on 2026-09-04. 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 5 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 3.0.1. Answer lives in: the release you run, set against each fixed version. GHSA-658g-p7jg-wx5g (critical) is fixed in the surveyed commit; which release carries it 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: 2 records name bruno with nothing tying them to this repository (CVE-2017-5589, CVE-2025-23988).
| 2026-09-04: CVE-2026-85665 (high): Bruno versions through 4.1.0 fail to validate file paths in request body declarations, allowing attackers to read arbitrary local files by using parent-director |
| 2026-08-21: GHSA-g747-7v24-2w4v (moderate), fixed in 4.0.0: OAuth2 state parameter is not validated on callback, allowing authorization code injection |
| 2026-03-31: GHSA-658g-p7jg-wx5g (critical), fixed in 3.2.1: Axios npm Supply Chain Incident Impacting @usebruno/cli |
| 2025-11-28: GHSA-246j-fv2m-6jhx (critical), fixed in 2.14.4: SHA1-Hulud supply-chain compromise (transitive @postman/tunnel-agent) — Upgrade @usebruno/cli to 2.14.4 |
| 2025-04-01: GHSA-hffg-7v8v-79j3 (high), fixed in 1.39.1: Safe-Mode ignored in Asserts expressions |
Observability & Operations
adequateNo telemetry or error reporting is wired in anywhere
adequateNone of 4,172 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.
| searched 4,172 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched |
No structured logging library is in use
adequateNothing 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.
| searched 4,172 files for 10 structured logging libraries; 0 matched |
No error reporter is wired in
adequateNothing 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.
| no error reporter initialised |
