[dependabot]

Bumps sitemap from 8.0.0 to 9.0.1.

Release notes

Sourced from sitemap's releases.

9.0.1 — Security Patch

Security Fixes

• BB-01: Fix XML injection via unescaped xslUrl in stylesheet processing instruction
• BB-02: Enforce 50,000 URL hard limit in XMLToSitemapItemStream parser
• BB-03: Cap parser error array at 100 entries to prevent memory DoS
• BB-04: Reject absolute destinationDir paths in simpleSitemapAndIndex to prevent arbitrary file writes
• BB-05: parseSitemapIndex now destroys source and parser streams immediately when maxEntries limit is exceeded
• Many thanks to @​maru1009 For the report

9.0.0

This major release modernizes the package with ESM-first architecture, drops support for Node.js < 20, and includes comprehensive security and robustness improvements.

[BREAKING CHANGES]

Dropped Node.js < 20 Support

• Node.js >=20.19.5 now required (previously >=14.0.0)
• npm >=10.8.2 now required (previously >=6.0.0)
• Dropped support for Node.js 14, 16, and 18

ESM Conversion with Dual Package Support

• Package now uses "type": "module" in package.json

• Built as dual ESM/CJS package with conditional exports

• Import paths in ESM require .js extensions (TypeScript will add these automatically)

• Both ESM and CommonJS imports continue to work:

  // ESM (new default)
  import { SitemapStream } from 'sitemap'
  // CommonJS (still supported)
  const { SitemapStream } = require('sitemap')

• CLI remains ESM-only at dist/esm/cli.js

Build Output Changes

• ESM output: dist/esm/ (was dist/)
• CJS output: dist/cjs/ (new)
• TypeScript definitions: dist/esm/index.d.ts (was dist/index.d.ts)

Node.js Modernization

• All built-in Node.js modules now use node: protocol imports (node:stream, node:fs, etc.)
• Uses native promise-based pipeline from node:stream/promises (instead of promisify(pipeline))
• TypeScript target updated to ES2023 (from ES2022)

... (truncated)

Changelog

Sourced from sitemap's changelog.

9.0.1 — Security Patch

• BB-01: Fix XML injection via unescaped xslUrl in stylesheet processing instruction — special characters (&, ", <, >) in the XSL URL are now escaped before being interpolated into the <?xml-stylesheet?> processing instruction
• BB-02: Enforce 50,000 URL hard limit in XMLToSitemapItemStream — the parser now stops emitting items and emits an error when the limit is exceeded, rather than merely logging a warning
• BB-03: Cap parser error array at 100 entries to prevent memory DoS — XMLToSitemapItemStream now tracks a separate errorCount and stops appending to the errors array beyond LIMITS.MAX_PARSER_ERRORS
• BB-04: Reject absolute destinationDir paths in simpleSitemapAndIndex to prevent arbitrary file writes — passing an absolute path (e.g. /tmp/sitemaps) now throws immediately with a descriptive error
• BB-05: parseSitemapIndex now destroys source and parser streams immediately when the maxEntries limit is exceeded, preventing unbounded memory consumption from large sitemap index files
