**After Remediation**: 0 high/critical security vulnerabilities (6 deprecation warnings remain)

**Severity Distribution (Before)**:

- Critical: 6 alerts (4 packages)

- High: 52 alerts (18 packages)

- Medium: 24 alerts (13 packages)

- Low: 9 alerts (7 packages)

**Severity Distribution (After)**:

| glob | ~11.0.3 | ~11.1.0 | CLI command injection (3 alerts) |

Based on best practices from major open source projects (React, Electron, VSCode), we follow this workflow:

Before and after EACH fix tier:

yarn install

yarn lint

yarn test

yarn build

If any step fails:

1. Revert the change

2. Document the issue

3. Move to "Deferred" category

4. Continue with next fix

These are deprecation warnings, not security vulnerabilities:

| Package | Issue | Recommendation |

| --------------------------------------- | ------------------------------- | ------------------------------------------------------------- |

| @babel/plugin-proposal-class-properties | Merged to ES standard | Replace with @babel/plugin-transform-class-properties |

| @kayahr/jest-electron-runner | No longer maintained | Find alternative or accept risk |

| convert-svg-to-png | Deprecated | Remove if not used (puppeteer already handles SVG conversion) |

| electron-notarize | Renamed | Replace with @electron/notarize |

| eslint | Version 8.x no longer supported | Upgrade to ESLint 9.x (major change) |

| puppeteer | < 24.15.0 no longer supported | Upgrade when ready for API changes |

**Issue**: Package is deprecated and has critical vulnerabilities in its dependencies.

**Current Usage**: Listed in devDependencies but `src/buildAssets.ts` uses puppeteer directly for SVG to PNG conversion via the `convertSvgToPng` function.

**Proposed Solution**: Remove convert-svg-to-png from devDependencies if not imported elsewhere.

**Action Required**:

- [ ] Verify convert-svg-to-png is not imported anywhere

- [ ] If used, replace with puppeteer-based solution

- [ ] Remove from devDependencies

**Issue**: Alerts list vulnerabilities in electron < 35.7.5, current is 39.2.5.

**Status**: Current version 39.2.5 should have these fixed.

**Action Required**:

- [ ] Verify electron 39.2.5 is not affected by listed CVEs

- [ ] Close related Dependabot alerts if confirmed fixed

**Issue**: sharp is locked to 0.29.3 via resolutions due to @fiahfy packages.

**Vulnerabilities**: Alerts for sharp < 0.30.5 and < 0.32.6 exist but apply to older versions.

**Action Required**:

- [ ] Check if @fiahfy packages work with newer sharp

- [ ] If not, consider alternative icon generation approach

- [ ] Test icon generation with updated sharp

**Issue**: electron-builder 26.0.3 has vulnerability in app-builder-lib.

**Status**: DEFERRED - User confirmed newer versions have bugs.

**Action Required**:

- [ ] Monitor for electron-builder fixes

- [ ] Test newer versions when stable
