Sourced from axios's releases.

v1.18.1 — June 21, 2026

This release focuses on Node HTTP adapter fixes, safer AxiosError serialisation, runtime/type correctness fixes, documentation updates, and dependency maintenance.

🐛 Bug Fixes

• AxiosError Serialisation: Made AxiosError#cause non-enumerable to prevent circular JSON serialisation failures when errors include nested causes. (#10913)
• Node HTTP Adapter: Guarded socket.setKeepAlive for proxy agent streams, accepted path-only URLs when socketPath is configured, deferred environment proxy handling to Node, and explicitly passed maxBodyLength through to follow-redirects. (#10917, #10930, #10942, #10993)
• Runtime and Type Correctness: Fixed several runtime crashes, type definition mismatches, and incorrect error handling paths. (#10959, #11021)
• AxiosURLSearchParams: Switched the encoder callback to an arrow function so encoder.call(this) receives the AxiosURLSearchParams instance correctly. (#11019)

🔧 Maintenance & Chores

• Documentation: Documented sensitive headers and status transition behaviour, prepared cleaned-up docs, added Deno install instructions, and clarified that request data is request-specific (#11007, #11010, #11023, #11025)

• Dependencies: Bumped vite, rollup, form-data, js-yaml, and multer across the root project, docs, smoke tests, and module test workspaces. (#11011, #11012, #11013, #11014, #11015, #11016, #11017, #11026)

Full Changelog

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)
