v1.18.0 — June 13, 2026

This release hardens redirect and URL handling, improves the validateStatus configuration semantics, and includes updates to documentation, dependencies, and release metadata.

🔒 Security Fixes

• Redirect Header Safety: Added Node HTTP adapter support for stripping caller-specified sensitive headers on cross-origin redirects, helping prevent custom auth headers such as API keys from leaking to another origin. (#10892)

• URL And Request Hardening: Rejects malformed http: and https: URLs that omit // with ERR_INVALID_URL, while tightening prototype-pollution-safe config reads, stream size limits, FormData depth handling, data URL sizing, and local NO_PROXY matching. (#11000)

🐛 Bug Fixes

• Status Validation: Added transitional.validateStatusUndefinedResolves so applications can opt in to treating validateStatus: undefined like the option was omitted, while validateStatus: null remains the explicit way to accept every status. (#10899)

🔧 Maintenance & Chores

• Documentation: Published the v1.17.0 release notes, fixed a changelog typo, clarified the package update PR policy, and marked the proxy request config as Node.js-only in the advanced docs. (#10984, #10988, #10992, #10995)

• Dependencies: Bumped @babel/core, @babel/preset-env, @commitlint/cli, @commitlint/config-conventional, @rollup/plugin-babel, @rollup/plugin-commonjs, @vitest/browser, @vitest/browser-playwright, eslint, lint-staged, rollup, vitest, and actions/checkout. (#10989, #10996, #10997)

• Release Metadata: Prepared the 1.18.0 release by updating package metadata and the runtime VERSION value. (#11003)
