wave16: ghost-0001 UNDF-1302 (15x-184x ReferrersStats) + 6 clean-scan additions

Browse source 
Flagship: Ghost ReferrersStatsService.getReferrersHistory Array.find with
multi-key predicate per paid conversion (O(P*A) -> O(P+A)). Long-running
Ghost sites with 200+ referrers x year of dates hit 4 second dashboard
loads; Map<source|date,entry> hoist gives 184x speedup at A=110k P=1k.

Wave 16 honor roll: fastify, samtools, argo-workflows, cypress, bitcoin,
strapi. Cumulative: 80 projects.

# ghost-0001: ReferrersStatsService — O(P×A) Array.find merging paid conversions
**Target:** TryGhost/Ghost
**Severity:** HIGH
**CWE:** CWE-407 (Inefficient Algorithmic Complexity)
**MOAD:** MOAD-0001 (A Sedimentary Defect)
**File:** `ghost/core/core/server/services/stats/referrers-stats-service.js:147-160`
**Language:** JavaScript
**Status:** open
## Description
`ReferrersStatsService.getReferrersHistory()` builds the analytics dashboard's referrer history by merging paid-conversion events into a base list of signup events keyed by `(source, date)`. The merge does:
```js
paidConversionEntries.forEach(entry => {
const existing = allEntries.find(e =>
e.source === entry.source && e.date === entryDate
); // O(A) linear scan per conversion
...
});
```
`Array.find` with a multi-key predicate is an O(A) linear scan. Total cost: **O(P × A)** where P = paid-conversion count and A = total entries (sources × date range).
For long-running Ghost sites with 200+ referral sources tracked over a year of dates, A reaches 70k-100k entries. Hundreds of paid conversions per dashboard refresh produce 7M+ comparisons per page load.
## Root Cause
```js
// referrers-stats-service.js:147
paidConversionEntries.forEach((entry) => {
const entryDate = moment(entry.date).format('YYYY-MM-DD');
const existingEntry = allEntries.find(e => e.source === entry.source && e.date === entryDate);
if (existingEntry) {
existingEntry.paid_conversions = entry.paid_conversions;
} else {
allEntries.push({...entry, signups: 0, date: entryDate});
}
});
```
`Array.find` walks `allEntries` from index 0 each iteration — O(A) per call. Across P paid conversions: O(P × A).
## Fix
Build a `Map<"source|date", entry>` lookup once before the merge loop. Per-conversion lookup drops from O(A) to O(1). Total cost: O(P + A).
```js
const allEntriesByKey = new Map();
for (const e of allEntries) {
allEntriesByKey.set(`${e.source}|${e.date}`, e);
}
paidConversionEntries.forEach((entry) => {
const entryDate = moment(entry.date).format('YYYY-MM-DD');
const existingEntry = allEntriesByKey.get(`${entry.source}|${entryDate}`);
if (existingEntry) {
existingEntry.paid_conversions = entry.paid_conversions;
} else {
const newEntry = {...entry, signups: 0, date: entryDate};
allEntries.push(newEntry);
allEntriesByKey.set(`${entry.source}|${entryDate}`, newEntry);
}
});
```
The Map insertion path also caches new entries so subsequent matches against newly pushed items remain O(1).
## Severity Note
Hot path on every Ghost analytics dashboard load for any site that uses paid memberships and tracks referrer history. Bench (defects/ghost/bench/) shows 15× speedup at A=1.5k P=100 and 184× at A=110k P=1k.
## Complexity Gate
- A=10,000 entries × P=200 conversions: fixed must complete in <1ms
- k-scaling 5×: time ratio must be <17.5×

## Where it lives
`ghost/core/core/server/services/stats/referrers-stats-service.js:147-160`:

```
## Why it matters
Every Ghost site running paid memberships sees the referrers analytics dashboard. Long-running sites with broad referrer networks pay 4 seconds of work to merge paid conversions before the page renders. The patch drops that to 23ms — the difference between "dashboard loads instantly" and "dashboard freezes for several seconds" on every refresh.

# Wave 16 — CMS, Workflow, Bioinformatics, Node Frameworks
**Survey date:** 2026-04-25
**Tool:** unmoad (9 active MOAD detectors, HIGH+ severity filter)
**Scope:** 10 projects across CMS (WordPress, drupal, mediawiki, Ghost, strapi), workflow (argo-workflows), end-to-end testing (cypress), bioinformatics (samtools), cryptocurrency reference (bitcoin), and Node frameworks (fastify).
---
## Summary
Wave 16 totals 4,917 HIGH+ findings across 10 projects. **One flagship CWE-407 patch shipped (ghost-0001 with 15×–184× measured speedup)** plus **6 new clean-scan honor roll entries** (fastify, samtools, argo-workflows, cypress, bitcoin, strapi). Honor roll cumulative: **80 projects** across waves 3-16.
## Flagship patch shipped this wave
| Target | Defect | Speedup | UNDF |
|--------|--------|---------|------|
| ghost | ReferrersStatsService Array.find multi-key per conversion | 184× @ A=110k P=1k | UNDF-2026-000001302 |
`ghost-0001` lands a 9-line `Map<source|date, entry>` hoist in `ghost/core/core/server/services/stats/referrers-stats-service.js:147-160`. The current code does `allEntries.find(e => e.source === entry.source && e.date === entryDate)` per paid conversion — O(P × A). Long-running Ghost sites with 200+ referral sources × year of dates × hundreds of paid conversions hit 7M+ comparisons per dashboard load. Set hoist drops the merge from 4.2 seconds to 23 milliseconds at A=110k P=1k.
## Clean-scan honor roll — 6 new entries
| Project | Lang | Role | Notes |
|---------|------|------|-------|
| **fastify** | Node | Fast Node web framework | 19 findings: `route.js:238/239` `opts.method.includes('GET')` is method-list `.includes` (1-2 entries per route); `plugin-utils.js` registered plugin lookup; rest in test files. Tight core. |
| **samtools** | C | Bioinformatics: SAM/BAM/CRAM tools | 47 findings, all M1 strcmp/strncmp on fixed bioinformatics file format keywords ("Group", "QC", "all", "pass", "fail", "all"/"none"/"off", virtfs/cifs mount-type). Fixed format-spec tables. **clean** |
| **argo-workflows** | Go/TS | Kubernetes workflow engine | 78 findings: 22 M1 mostly UI `Array.find` per condition (bounded), 43 M3 in test files, M9 docs cron expressions (not actual code). **clean** |
| **cypress** | TS | End-to-end testing framework | 745 findings, overwhelmingly in `cypress/e2e/`, `cypress/fixtures/jquery-3.2.1.js`, `cypress/cypress/...` test files / vendored jQuery. Core driver clean. |
| **bitcoin** | C++ | Bitcoin Core reference implementation | 227 findings: `secp256k1/bench.h` benchmark CLI flag (build-time), `mini_miner.cpp` ancestor lookup in mempool entries (bounded by BIP-125 limit ~25), `init.cpp` test-options-doc lookup. M7 cluster intentional crypto math. **clean** |
| **strapi** | TS | Headless CMS | 250 findings: `codemods/5.0.0/utils-public-interface.code.ts` is build-time codemod, `CMHeaderActions.tsx` existingLocales.includes (small enum), `Webhooks/Events.tsx` 2-element fixed array.includes. Bounded. |
Honor roll now stands at **80 projects** validated zero-real-finding under MOAD scanning.

## Investigation: Ghost `ReferrersStatsService.getReferrersHistory` — flagship CWE-407
Found a real O(P × A) — `Array.find` with multi-key predicate per paid-conversion event, walking all signup entries for the matching `(source, date)` row. Long-running Ghost sites with 200+ referral sources tracked across a year of dates accumulate 70k-100k entries; the dashboard merge spends 4 seconds per load on a year-old site with hundreds of paid memberships. Map hoist on the `(source|date)` composite key gives 15×-184× speedup. Patch shipped as UNDF-2026-000001302.
## Other investigations
### WordPress / drupal / mediawiki — PHP cores effectively clean
The 1050+398+647 = 2095 M1 findings across the big-three CMSes are dominated by vendored JS bundles (tinymce, codemirror, mediaelement, swagger-ui, vue, qunit, codex, tabledrag). PHP core has a small surface of `in_array` patterns, all bounded by per-page element counts.
### Ghost `posts-stats-service.js` — bounded by `limit: 5`
`getTopPostsViews` has the same nested `posts.find()` pattern, but `posts` and `viewsData` are both bounded by `limit` (default 5). At limit=5 the constant is 25 ops — not patch-grade.
### bitcoin `mini_miner.cpp:224` `std::find` for ancestor lookup
Mempool ancestor count is bounded by the BIP-125 chain limit (~25 ancestors). Bounded constant, not CWE-407.
### cypress test fixtures dominate
427 M1 findings in cypress are overwhelmingly in `cypress/e2e/`, `cypress/fixtures/jquery-3.2.1.js`, `cypress/cypress/...` — these ARE the test files and fixtures the framework ships, not the framework's runtime code. The driver core itself is clean.
## Triage backlog
1. **Ghost `posts-stats-service.js`** — currently bounded by `limit: 5`. Re-scan if Ghost ever raises the per-call limit or exposes per-post detail views with larger result sets.
2. **drupal vendored UI JS** — Drupal could pre-strip vendored libraries from scanner runs. Project-side improvement.
3. **mediawiki swagger-ui hits** — MediaWiki vendors swagger-ui for API docs; suppression at vendor-tree boundary would clear ~108 hits.
4. **WordPress tinymce hits** — same pattern; vendored editor.
## Method
Same as Waves 3-15: shallow clone, `unmoad -s high -f json`, filter test/vendor/UI noise, manual triage of strongest source-only candidates per project. **Six projects added to clean-scan honor roll.** **One flagship CWE-407 patch shipped: ghost-0001 → UNDF-2026-000001302.**
