Bump axios from 1.15.0 to 1.16.0

[dependabot]

Bumps axios from 1.15.0 to 1.16.0.

Release notes

Sourced from axios's releases.

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)

Stale comment

No blocking issues found in this dependency bump.

Security

• This is a net security improvement. axios@1.15.0 is inside multiple affected ranges published on 2026-04-24 and patched by >=1.15.1 / >=1.15.2, including GHSA-pmwg-cvhr-8vh7 / CVE-2026-42043 (incomplete NO_PROXY fix), GHSA-q8qp-cvcw-x6jj / CVE-2026-42264 (prototype-pollution gadgets in the HTTP adapter), and GHSA-3w6x-2g7m-8v23 / CVE-2026-42044 (prototype-pollution gadget in parseReviver). Several additional moderate advisories also list <=1.15.0 as affected.
• Moving to axios@1.16.0 gets the PR onto a patched line and also picks up the 1.16.0 adapter bug fixes around redirects, abort handling, timeouts, and header handling.
• Supply-chain delta is small: the PR only changes package.json and yarn.lock, introduces no new packages, and the only transitive metadata change is the declared follow-redirects range. The locked follow-redirects version remains 1.16.0.

Safety of merging

• In this repo, axios is only imported in src/utils/apiCallHandler.js, where it is used as plain get / post / put / delete helpers.
• I found no usage of the higher-risk axios options touched by the recent advisories or 1.16.0 behavior changes: no baseURL, validateStatus, withXSRFToken, paramsSerializer, beforeRedirect, proxy, responseType: 'stream', maxContentLength, or maxBodyLength usage in src/.
• The main 1.16.0 observable changes are fetch-adapter limit enforcement, proxy Host header preservation, URL-decoding of basic-auth credentials in URLs, stricter protocol parsing, and UTF-8 encoding fixes. None of those appear to be exercised by this codebase's current axios usage.

Local verification

• yarn lint ✅
• CI=true yarn test ✅ (92 suites / 820 tests passed)
• yarn start ✅ (webpack compiled successfully)
• yarn exec cypress run could not be completed locally because the Cypress binary was not present in the machine cache, and an attempted cypress install did not produce a usable binary in this environment.

Recommendation

• Merge with caution: the version bump improves security and looks low-risk for this repository's axios usage, but I would still wait for the PR's test-cypress GitHub check to pass before merging, since local end-to-end coverage was not available here.

No blocking issues found in this dependency bump.

Security

• This update improves the security posture compared with axios 1.15.0.
• GitHub advisory data shows axios 1.15.0 is still inside several affected ranges that were only patched in 1.15.1 / 1.15.2, including high-severity prototype-pollution gadgets leading to header injection / request hijacking (GHSA-6chq-wfr3-2hj9, GHSA-pf86-5x62-jrwf), the incomplete NO_PROXY fix specific to 1.15.0 (GHSA-pmwg-cvhr-8vh7), and additional moderate issues such as XSRF token leakage and JSON response tampering (GHSA-xx6v-rp6x-q39c, GHSA-3w6x-2g7m-8v23).
• The transitive update to follow-redirects 1.16.0 also fixes CVE-2026-40895, where custom auth-style headers could be forwarded across cross-domain redirects in Node.
• I did not find a known advisory that newly affects axios 1.16.0.

Safety Of Merging

• Scope is minimal: only package.json and yarn.lock change.
• In this repository, runtime usage is limited to src/utils/apiCallHandler.js, which uses plain axios.get/post/put/delete calls with headers and withCredentials.
• I found no local use of the higher-risk axios features touched by 1.16.0's notable behavior changes, such as axios.create, proxy, maxRedirects, maxBodyLength, maxContentLength, custom Host headers, URL-embedded basic auth, withXSRFToken, validateStatus, or parseReviver.
• Upstream 1.16.0 changes are mostly around Node/fetch adapter redirects, abort cleanup, proxy/header handling, timeout handling, and stricter protocol parsing, so regression risk for this browser-focused app looks low.

Test Results

• yarn install --immutable ✅
• yarn lint ✅
• CI=true yarn run test --coverage --maxWorkers=4 --workerThreads=true --reporters=default --reporters=jest-junit --reporters=jest-github-actions-reporter ✅ (92 suites, 820 tests)
• yarn exec cypress run --config-file cypress.config.mjs --browser chrome could not be completed here because the Cypress binary was not installed in the agent and downloading it from download.cypress.io failed in this environment (OpenSSL SSL_connect: SSL_ERROR_SYSCALL). That looks like an environment egress limitation rather than a regression from this PR.

Recommendation

Merge with caution. I do not see a code-level reason to hold this update, and it resolves known issues present in axios 1.15.0. The only caution is that I could not run Cypress locally in this cloud environment, so I would rely on normal CI/e2e coverage or rerun e2e in an environment that can download the Cypress binary if you want full end-to-end validation before merging.
