[dependabot]

Bumps axios from 1.15.0 to 1.16.1.

Release notes

Sourced from axios's releases.

v1.16.1 — May 13, 2026

This release ships a defence-in-depth fix for prototype pollution in formDataToJSON, hardens proxy and CI workflows, restores Webpack 4 compatibility for the fetch adapter, and includes several small bug fixes and maintenance improvements.

🔒 Security Fixes

• Prototype Pollution Defence-in-Depth: Hardened formDataToJSON against already-polluted Object.prototype by walking own properties only, so attacker-controlled keys inherited from a poisoned prototype cannot propagate through deserialization. (#7413)
• Proxy Cleartext Leak: Fixed an issue where HTTPS request data could be transmitted in cleartext to an HTTP proxy under certain configurations. (#10858)
• CI Cache Removal: Removed all GitHub Actions caches as a defence-in-depth measure against cache poisoning vectors in the build pipeline. (#10882)

🐛 Bug Fixes

• Data URI Parsing: Updated the fromDataURI regex to match RFC 2397 more strictly, fixing edge cases in data: URL handling. (#10829)
• Unicode Headers: Preserved Unicode header values when running through request interceptors, so non-ASCII header content is no longer corrupted before dispatch. (#10850)
• XHR Upload Progress: Guarded against malformed ProgressEvent payloads emitted by some environments during XHR upload, preventing crashes when loaded / total are missing or invalid. (#10868)
• Webpack 4 Fetch Adapter: Fixed an "unexpected token" error caused by syntax in the fetch adapter that Webpack 4 could not parse, restoring compatibility for legacy bundler users. (#10864)
• Type Definitions: Made parseReviver context.source optional in the type definitions to align with the ES2023 specification. (#10837)
• URL Object Support Reverted: Reverted the change that allowed passing a URL object as config.url (originally #10866) due to regressions; this support will be reintroduced in a later release once the underlying issues are addressed. (#10874)

🔧 Maintenance & Chores

• Cycle Detection Refactor: Replaced the array-based cycle tracker in toJSONObject with a WeakSet, improving performance and memory behaviour on large nested structures. (#10832)
• composeSignals Cleanup: Refactored composeSignals to use a clearer early-return structure, simplifying the cancellation/abort composition path. (#10844)
• AI Readiness & Repo Docs: Added AGENTS.md and related contributor-guide updates for both human and AI agents, plus post-release documentation improvements. (#10835, #10841)
• Docs Improvements: Clarified the GET request example, fixed the interceptor eject example to reference the correct instance, and corrected the Buzzoid sponsor description in the README. (#10836, #10853, #10856)
• Sponsorship Tooling: Fixed empty sponsor arrays in the sponsor processing script, added the ability to inject additional sponsors, updated the sponsorship link, and added a Twicsy advertisement entry. (#10843, #10859, #10869)
• Dependencies: Bumped @commitlint/cli from 20.5.0 to 20.5.2. (#10846)

Changelog

v1.16.0 — May 2, 2026

This release adds support for the QUERY HTTP method and a new ECONNREFUSED error constant, lands a substantial wave of HTTP, fetch, and XHR adapter bug fixes around redirects, aborts, headers, and timeouts, and welcomes 23 new contributors.

⚠️ Notable Changes

A handful of fixes in this release are either security-adjacent or change observable behaviour. Please review before upgrading:

• Fetch adapter now enforces maxBodyLength and maxContentLength. These limits were silently ignored on the fetch adapter prior to 1.16.0 — anyone relying on them as a safety net (DoS protection, accidental large uploads) had no protection. (#10795)
• Proxy requests now preserve user-supplied Host headers. Previously, the proxy path could overwrite a custom Host. Virtual-host-style routing through a proxy will now behave correctly. (#10822)
• Basic auth credentials embedded in URLs are now URL-decoded. If you have percent-encoded credentials in a URL (e.g. https://user:p%40ss@host), the decoded value is what now goes on the wire. (#10825)
• parseProtocol now strictly requires a colon in the protocol separator. Strings that loosely parsed as protocols before may no longer match. (#10729)
• Deprecated unescape() replaced with modern UTF-8 encoding. Non-ASCII URL handling is now spec-correct; consumers depending on legacy unescape() quirks may see different output bytes. (#7378)
• transformRequest input typing change was reverted. The typing change introduced in #10745 was reverted in #10810 after follow-up review — net behavior is unchanged from 1.15.2. (#10745, #10810)

🚀 New Features

• QUERY HTTP Method: Added support for the QUERY HTTP method across adapters and type definitions. (#10802)
• ECONNREFUSED Error Constant: Exposed ECONNREFUSED as a constant on AxiosError so callers can match connection-refused failures without comparing string literals (closes #6485). (#10680)
• Encode Helper Export: Exported the internal encode helper from buildURL so userland param serializers can reuse the same encoding logic that axios uses internally. (#6897)

🐛 Bug Fixes

• HTTP Adapter — Redirects & Headers: Cleared stale headers when a redirect targets a no-proxy host, fixed the redirect listener chain so listeners no longer stack across hops, restored the missing requestDetails argument on beforeRedirect, preserved user-supplied Host headers when forwarding through a proxy, and properly URL-decoded basic auth credentials. (#10794, #10800, #6241, #10822, #10825)
• HTTP Adapter — Streams & Timeouts: Preserved the partial response object on AxiosError when a stream is aborted after headers arrive, honoured the timeout option during the connect phase when redirects are disabled, and resolved an unsettled-promise hang when an aborted request was combined with compression and maxRedirects: 0. (#10708, #10819, #7149)
• Fetch Adapter: Enforced maxBodyLength / maxContentLength in the fetch adapter, set the User-Agent header to match the HTTP adapter, preserved the original abort reason instead of replacing it with a generic error, and deferred global access so importing the module no longer throws a TypeError in restricted environments. (#10795, #10772, #10806, #7260)
• XHR Adapter: Unsubscribed the cancelToken and AbortSignal listeners on the error, timeout, and abort code paths to prevent leaked subscriptions. (#10787)
• Error Handling: Attached the parsed response to AxiosError when JSON.parse fails inside dispatchRequest, prevented settle from emitting undefined error codes, and tightened the parseProtocol regex to require a colon in the protocol separator. (#10724, #7276, #10729)
• Types & Exports: Aligned the CommonJS CancelToken typings with the ESM build, fixed a compiler error caused by RawAxiosHeaders, and re-exported create from the package index. (#7414, #6389, #6460)
• UTF-8 Encoding: Replaced the deprecated unescape() call with a modern UTF-8 encoding implementation. (#7378)
• Misc Cleanup: Resolved a batch of small inconsistencies and gadget-level issues across the codebase. (#10833)

🔧 Maintenance & Chores

• Refactor — ES6 Modernisation: Modernised the utils module and XHR adapter to use ES6 features, and tidied the multipart boundary error message. (#10588, #7419)
• Tests: Hardened the HTTP test server lifecycle to fix flaky FormData EPIPE failures, fixed Win32 platform support for the pipe tests, and corrected an incorrect test assumption. (#10820, #10791, #10796)
• Docs: Documented paramsSerializer.encode for strict RFC 3986 query encoding, updated the parseReviver TypeScript definitions and configuration docs for ES2023, added timeout guidance to the README's first async example, and expanded notes around the recent type changes. (#10821, #10782, #10759, #10804)
• Reverted: Reverted the transformRequest input typing change from #10745 after follow-up review. (#10745, #10810)
• Dependencies: Bumped actions/setup-node, the github-actions group, and postcss (in /docs) to their latest versions. (#10785, #10813, #10814)
• Release: Updated changelog and packages, and prepared the 1.16.0 release. (#10790, #10834)

Dependabot bump, standard diff (package.json + package-lock.json only). Two security fixes in this range make this worth shipping promptly:

• Proxy cleartext leak (1.16.1 #10858): HTTPS request data could be sent in cleartext to an HTTP proxy. Relevant if x402-api makes any outbound axios calls in environments with a proxy configured.
• Prototype pollution defence-in-depth (1.16.1 #7413): formDataToJSON now walks own-properties only, preventing attacker-controlled inherited keys from propagating through deserialization.

Also picks up the 1.16.0 wave: HTTP adapter redirect/header hardening, fetch adapter maxBodyLength/maxContentLength enforcement, XHR listener leak fix, and ECONNREFUSED constant exposure.

No breaking changes noted. Compatibility score is green. Good to merge.
