security: disposition all 55 code-scanning alerts (8 fixed, 47 dismissed with reasons) - #95
Conversation
Eight fixed in code, 47 dismissed with recorded reasons. Full record in
docs/security/2026-08-31-code-scanning-disposition.md, which every dismissal comment points at.
WHY THEY APPEARED AFTER v2.0.0 CLAIMED ZERO
The claim was measured on the release PR and was true there. A pull-request CodeQL run analyses the
merge commit in a diff-informed mode; the push to the default branch runs a FULL analysis. When
v2.0.0 merged, that full run surfaced 55 pre-existing findings in code this fork had been carrying
all along -- none introduced by v2.0.0. The release notes, README and ROADMAP now say what was
actually measured, because "zero alerts on a PR" and "zero alerts on the default branch" are
different claims and the table did not distinguish them.
FIXED BY DELETING DEAD CODE (6 alerts, 3 high + 3 medium)
src/web/ has been dead since v1.7.1 removed the web application, but eight files survived -- and
the runtime image was shipping all of them. Established before deleting:
* nothing imports them (grep across src/node/ and src/core/)
* the build cannot work: src/web/index.js imports ./stylesheets/index.js, which does not exist,
nor do html/index.html or static/ga.html. `npx grunt prod` fails with 39 webpack errors.
* `find /app/src/web -type f` in the published v2.1.0 image returned all eight
So browser postMessage handlers with three high-severity findings were being copied into a server
image nobody could reach them from. Deleted rather than suppressed.
The `dev` and `prod` Grunt tasks go with them, replaced by one that says the web app is gone and
points at `npm run mcp`. A task that cannot succeed is worse than an absent one -- it invites
someone to debug a build for a product this repository does not ship. The `eslint:web` target is
removed too. The webpack/copy config blocks are left alone deliberately: they are inert now, and
they share structure with what `grunt configTests` needs.
FIXED PROPERLY (2 alerts)
benchmarks/operation-benchmarks.mjs declared testData1MB and testData10MB and never used them.
`"A".repeat()` builds eagerly, so every benchmark run allocated 11 MB and threw it away. Its header
also said @license Apache-2.0 -- wrong since the v2.0.0 relicense, and the only fork-owned file
still saying it against 62 that are correct.
DISMISSED WITH REASONS (47)
44 src/core/vendor/** -- GOST crypto and the x86 disassembler. All code-quality rules, none with
a security severity. Seven of the eight files are byte-identical to upstream v11.4.0; the
eighth differs only by patches/fork/01, and its alert is on an upstream line. A hand-edit to
a mirrored file is silently reverted by the next sync -- documented, not hypothetical, in
2026-08-30-saferegex-reverted-by-upstream-sync.md. Carrying 44 patches against a vendored
library to satisfy quality rules would be a permanent rebase cost for no security benefit.
Collected for upstream report in #73 instead, where a fix helps every CyberChef user.
1 src/core/ChefWorker.js -- upstream browser Web Worker entry point, flagged line is upstream's,
unreachable from the MCP server. Not deleted, unlike src/web/, because this file IS on the
sync allowlist and patch 03 applies to it.
1 src/core/config/scripts/newOperation.mjs -- dev scaffolding for `npm run newop`, byte-identical
to upstream, verified absent from the runtime image. High by rule, unreachable in fact.
1 src/core/operations/FromBCD.mjs -- byte-identical to upstream; a real if minor correctness
smell, so reported upstream rather than patched here.
Of the eight security-severity alerts, seven are fixed by deletion and one is dismissed as
unreachable. None is suppressed while remaining live in the shipped product.
Worth recording for whoever automates this: `dismissed_comment` is capped at 280 characters, and an
over-long value fails the whole PATCH with an HTTP 422 that is easy to swallow -- 47 dismissals
failed silently that way before the cap was found.
Verified: lint clean, 805 MCP tests (26 files), 2289 operations, 241 Node-API, image builds and no
longer contains /app/src/web.

🟡 Changes recommended
grunt dev/grunt prod now succeed as stubs while npm start/npm run build still invoke them, which can silently report “success” without producing a build.

Pull request overview
This PR closes out all open CodeQL code-scanning alerts by (1) removing unreachable/shipping dead web-worker code, (2) fixing two real benchmark issues, and (3) recording the rationale for all dismissals in a dedicated security disposition document, while also correcting prior documentation that overstated “zero alerts” based on PR-only measurements.
Changes:
- Deleted leftover
src/web/**worker/waiter files that were orphaned since v1.7.1 but still present in the runtime image, eliminating multiple high/medium alerts by removal. - Updated build/lint plumbing and project documentation (Grunt tasks, README, release notes, roadmap, changelog) to reflect the correct CodeQL measurement nuance and the disposition outcome.
- Removed unused benchmark fixtures (preventing eager allocation) and corrected licensing header metadata in
benchmarks/operation-benchmarks.mjs.

…rt/build
Raised in review, and correct: the replacement `dev`/`prod` tasks printed a message and exited 0.
Before this PR `grunt prod` FAILED, with 39 webpack errors -- so the stub turned an outdated caller
from red to green while it still produced nothing, which is a worse outcome than the broken build it
replaced. A build command that does not build must not report success. Now `grunt.fail.fatal`, which
exits 1 and still explains what to run instead.
Following the same thread found a bigger trap than the exit code. `npm start` and `npm run build` --
the two most conventional script names in any JS project -- were mapped to `grunt dev` and
`grunt prod`, so anyone running either on this repository invoked a web build removed in v1.7.1.
Making the task fatal would have turned that from a silent no-op into a hard failure on the most
obvious commands in the project.
Repointed to what they should mean here:
npm start -> node --openssl-legacy-provider src/node/mcp-server.mjs (runs the server)
npm run build -> npx grunt configTests (generates OperationConfig.json + src/node/index.mjs,
which IS this project's build step and the one every
CI job, the Dockerfile and the setup docs already run)
Verified: `grunt prod` exits 1 with the explanation; `npm run build` generates config and exits 0;
`npm start` answers tools/list with 24 tools. Nothing in CI invoked grunt dev/prod (core-ci.yml has
said so since v1.7.1). The `npm run build` references in docs/guides/codecov-integration.md are
pre-test setup steps and are now more correct than before, since they generate config instead of
invoking a broken web build. AGENTS block updated to match.
805 MCP tests, lint clean.

All three raised in review, all three mine. * The summary said seven of the eight security-severity alerts were fixed by deletion and one dismissed. It is six and two: the six src/web worker alerts are deleted, ChefWorker.js is dismissed as unreachable, and newOperation.mjs as absent from the runtime image. The table below it was already right, which is how the mismatch was spotted. * It described the retained webpack/copy/zip config blocks as "inert". They are not: no registered task references them, but Grunt lets any target be invoked directly, so `npx grunt webpack:web` still runs and still fails with 12 errors. The document now says exactly that -- composite tasks retired, individual targets not -- and records that removing them was attempted and reverted, because they share a top-level const chain with the config `grunt configTests` and `grunt node` depend on and excising them broke the file with a SyntaxError. * The CHANGELOG lumped FromBCD.mjs in with "unreachable or absent from the runtime image". It is neither -- it is a live operation, dismissed because it is byte-identical to upstream and reported there instead. No code change; the Gruntfile is byte-identical to the previous commit after the reverted experiment.

All three from review. `"start": "npm run mcp"` rather than repeating the node flags and entry path. That duplication is the same failure mode this release spent its day fixing -- four copies of an argument-name sanitisation that had already drifted, three copies of an HTML stripper. Two copies of a launch command would have drifted the same way the moment one of them needed a flag. Verified the alias still starts the server: tools/list answers with 24 tools. Plus an Oxford comma and "easy to miss if stderr is redirected" in place of "easy to swallow", which also lets that sentence carry the concrete detail -- 47 dismissals failed silently exactly that way.

Adjudication — round 2Blocking: none. All three adopted. Suggestion:
|
Three of four findings adopted; one rejected on evidence.
- **Global fetch leak (blocking, adopted).** `installWasmFetch()` replaces
`globalThis.fetch` for the whole worker and the block never restored it. Vitest
isolates by file so the blast radius was this file, but a patched global outliving
the tests that needed it is how an unrelated suite fails confusingly later. Saved and
restored around the block -- deliberately `beforeAll`/`afterAll` rather than
per-test: the module is idempotent by design, so a per-test restore leaves
`installed` true with the wrapper gone and the next call cannot put it back. That was
not theoretical; the per-test version failed the payload test immediately.
- **Test named for a case it did not exercise (adopted).** "accepts a URL object as
well as a string" only ever passed a string. It now asserts both halves: the
predicate sees a string, and the wrapper normalises a real `URL` via `.href`.
- **Ignored return values in setup (adopted).** The two `checkLimit` calls seeding the
stats test are now asserted, so a silent failure there cannot masquerade as setup.
- **Disconnected assertion (adopted).** The `oversized` dummy object was declared,
asserted against, and never passed to anything -- meaningless. Removed, and replaced
with an assertion that the error names the actual limit.
REJECTED -- "the PR claims src/web deletion, npm start/build fixes and benchmark fixes
that are missing from the diff". They are not missing; they are already on master:
src/web/ absent -- deleted in #95 (merged, 7b0afd5)
npm start -> npm run mcp already set (c7b48f4)
npm run build -> configTests already set (c7b48f4)
benchmark fixtures already removed; no testData1MB/10MB remains
The review compared the release NARRATIVE (CHANGELOG and release notes, which describe
the whole v2.1.1 release) against the DIFF (which contains only what is new since
master). For a release-prep PR those are different by construction.

Disposition of all 55 code-scanning alerts
8 fixed in code. 47 dismissed with reasons, each dismissal pointing at
docs/security/2026-08-31-code-scanning-disposition.md.src/web/workers/**, orphaned since v1.7.1benchmarks/unused 11 MB fixturessrc/core/vendor/**(GOST crypto, x86 disassembler)src/core/ChefWorker.jssrc/core/config/scripts/newOperation.mjssrc/core/operations/FromBCD.mjsOf the eight alerts with a security severity, seven are fixed by deletion and one is dismissed as unreachable. None is suppressed while remaining live in the shipped product.
First: why v2.0.0's "zero alerts" was wrong
It was measured on the release PR, and it was true there — both APIs returned 0 immediately before merge.
A pull-request CodeQL run analyses the merge commit in a diff-informed mode. The push to the default branch runs a full analysis. v2.0.0 merged, CodeQL ran fully against
masterfor the first time in months, and surfaced 55 pre-existing findings.Two things follow, both now recorded:
Fixed by deletion:
src/web/was dead and shipping (6 alerts, 3 high)Browser
postMessagehandlers —js/remote-property-injection×2 (high),js/missing-origin-check×4 (medium).The web app went in v1.7.1; eight files survived. Established before deleting anything:
grep -rlacrosssrc/node/andsrc/core/finds no reference.src/web/index.jsimports./stylesheets/index.js, which does not exist; nor dohtml/index.htmlorstatic/ga.html. Confirmed by running it:npx grunt prodfails with 39 webpack errors, and has since v1.7.1.find /app/src/web -type fin the published v2.1.0 image returned all eight, because the Dockerfile's prune list never namedsrc/web.So dead browser code carrying three high-severity findings was being copied into a server image nobody could reach it from. Deleted, not suppressed.
The
dev/prodGrunt tasks go too, replaced by one that explains the web app is gone and points atnpm run mcp— a task that cannot succeed is worse than an absent one.eslint:webremoved. Thewebpack:web/copy:standaloneconfig blocks are deliberately left: inert now, and they share structure with whatgrunt configTestsneeds, so untangling them risks the one Grunt path this project actually uses.Fixed properly: benchmarks (2 alerts)
testData1MBandtestData10MBdeclared, never used — and"A".repeat()builds eagerly, so every run allocated 11 MB and discarded it. Also fixed the file's@license Apache-2.0header, wrong since the v2.0.0 relicense and the only fork-owned file still carrying it (62 others are correct).Dismissed: 44 upstream vendor alerts
All code-quality rules —
js/unused-local-variable×16,js/trivial-conditional×6,js/automatic-semicolon-insertion×6, etc. None carries a security severity.Seven of the eight flagged files are byte-identical to CyberChef v11.4.0; the eighth (
gostRandom.mjs) differs only bypatches/fork/01, and its alert is on an upstream line — our patch is at 114–129, the alert at 46.A hand-edit to a mirrored file is silently reverted by the next sync. That is documented history here, not theory: a ReDoS mitigation was reverted and stayed gone for four releases while three documents claimed it was active. Carrying 44 patches against a vendored library — each needing a rebase on every upstream release — to satisfy quality rules with no security consequence is a permanent cost for no benefit.
Collected for upstream report in #73 instead, where a fix helps every CyberChef user.
Dismissed: three upstream files, on reachability
ChefWorker.js(medium) — the web app's Worker entry point; nothing insrc/node/references it. Line 48 is upstream's; our only change is patch 03 at line 9. Not deleted, unlikesrc/web/, because this file is on the sync allowlist — deleting it would be reverted and would break patch 03 loudly.newOperation.mjs(high) — dev scaffolding fornpm run newop, byte-identical to upstream, and verified absent from the runtime image. High by rule; the TOCTOU is between a developer and themselves.FromBCD.mjs(warning) — byte-identical to upstream. A real if minor correctness smell, so reported upstream rather than patched here.One note for whoever automates this next
dismissed_commenton the code-scanning API is capped at 280 characters, and an over-long value fails the entire PATCH with an HTTP 422. 47 dismissals failed silently that way before the cap was found — the comments now carry a one-line summary plus a pointer to the disposition document.Verification
