Fix GitHub Security reports

Run the following 2 commands to get security advisiories and dependabot alerts respectively for this repo and create a plan to fix them.

Security advisories

gh api -H "Accept: application/vnd.github+json" -H "X-GitHub-Api-Version: 2022-11-28" /repos/{owner}/{repo}/security-advisories

Dependabot alerts

gh api -H "Accept: application/vnd.github+json" -H "X-GitHub-Api-Version: 2022-11-28" /repos/{owner}/{repo}/dependabot/alerts

I'll start by fetching both the security advisories and dependabot alerts for this repo.

Now let me check the dependency chain: eslint → file-entry-cache → flat-cache → flatted:

bash

bash

{ flatted: '^3.4.1', hookified: '^1.15.0', cacheable: '^2.3.3' }

{ keyv: '^4.5.4', flatted: '^3.2.9' }

claude-opus-4-6 · 2026-03-20 12:07:54 · ~17 tokens

Good. The flat-cache@4.0.1 depends on flatted@^3.2.9, which resolves to the vulnerable 3.3.4. Since the fix is in 3.4.0, ^3.2.9 is compatible with 3.4.0+. Let me check if we can just update the lockfile:

Security Report & Fix Plan

Summary

| Category | Count | |---|---| | Security Advisories | 0 (none) | | Dependabot Alerts (Open) | 1 | | Dependabot Alerts (Fixed) | 29 |

The One Open Alert

| # | Package | Severity | CVE | Vulnerable | Patched | Manifest | Scope | |---|---------|----------|-----|------------|---------|----------|-------| | 78 | flatted | 🔴 HIGH (CVSS 7.5) | CVE-2026-32141 | < 3.4.0 | 3.4.0 | pnpm-lock.yaml | runtime (transitive) |

Vulnerability: Unbounded recursion DoS in flatted.parse() revive phase. A crafted payload with deeply nested $ indices causes a stack overflow, crashing the Node.js process. Any application passing untrusted input to flatted.parse() can be crashed by a single request.

Dependency chain:

eslint@9.28.0
  └── file-entry-cache@8.0.0
        └── flat-cache@4.0.1
              └── flatted@3.3.4  ← VULNERABLE (needs ≥ 3.4.0)

Fix Plan

The fix is straightforward. flat-cache@4.0.1 declares flatted: ^3.2.9, which is semver-compatible with 3.4.0+. A pnpm override will force resolution to the patched version.

Step 1: Add flatted override to package.json

In the pnpm.overrides section, add:

"flatted": ">=3.4.0"

So it becomes:

"pnpm": {
  "overrides": {
    "serialize-javascript": ">=7.0.3",
    "diff": ">=8.0.3",
    "flatted": ">=3.4.0"
  }
}

Step 2: Regenerate the lockfile

pnpm install

Step 3: Verify the fix

grep "flatted@" pnpm-lock.yaml
# Should show flatted@3.4.x, no more 3.3.4

Step 4: Run tests to confirm no regressions

pnpm test

Risk Assessment

| Factor | Assessment | |---|---| | Breaking change risk | ⬇️ Very low — 3.3.4 → 3.4.0 is a minor bump; the fix converts recursive revive() to an iterative stack-based loop (no API changes) | | Runtime impact | This is a runtime transitive dep (used by eslint's caching layer for ...

Now create a draft PR from these changes. Follow the repo conventions for your branch name and commit title. The PR (commit) description should be based on the implementation plan and the changes summary but not be overly long or detailed.

Add the plan as a commit note using git note feature.

Check if you are already on a relevant branch before creating a new branch.

 ### Gotcha

-* **AGENTS.md must be excluded from markdown linters**: AGENTS.md is auto-managed by lore and uses \`\*\` list markers and long lines that violate typical remark-lint rules (unordered-list-marker-style, maximum-line-length). When a project uses remark with \`--frail\` (warnings become errors), AGENTS.md will fail CI. Fix: add \`AGENTS.md\` to \`.remarkignore\`. This applies to any lore-managed project with markdown linting.

-* **Consola prompt cancel returns truthy Symbol, not false**: When a user cancels a \`consola\` / \`@clack/prompts\` confirmation prompt (Ctrl+C), the return value is \`Symbol(clack:cancel)\`, not \`false\`. Since Symbols are truthy in JavaScript, checking \`!confirmed\` will be \`false\` and the code falls through as if the user ...

The AGENTS.md has lore-managed content changes (removing entries not relevant to this repo). Per the instructions, I need to include AGENTS.md in the commit.

## Implementation Plan

### Problem
Dependabot alert #78: flatted < 3.4.0 is vulnerable to CVE-2026-32141
(GHSA-25h7-pfq9-p65f), a HIGH severity unbounded recursion DoS in the
parse() revive phase (CVSS 7.5).

### Analysis
- flatted@3.3.4 is a transitive runtime dependency
- Dependency chain: eslint → file-entry-cache@8.0.0 → flat-cache@4.0.1 → flatted@3.3.4
- flat-cache@4.0.1 declares flatted@^3.2.9 (compatible with >=3.4.0)
- Fix version: flatted@3.4.0 (converts recursive revive() to iterative stack-based loop)

### Fix
1. Added pnpm override: "flatted": ">=3.4.0" in package.json pnpm.overrides
   - Consistent with existing overrides for serialize-javascript and diff
2. Regenerated pnpm-lock.yaml: flatted resolved to 3.4.2
3. Verified all 38 tests pass with 100% statement coverage

### Risk Assessment
- Breaking change risk: Very low (3.3.4 → 3.4.x, minor bump, no API changes)
- Runtime impact: flatted is used by eslint's caching layer, not the library itself
- Override pattern: ...
