axios

This release backports security fixes from v1.x, hardens the CI/CD supply chain with OIDC publishing and zizmor scanning, resolves TypeScript typing issues in AxiosInstance, and fixes a performance regression in isEmptyObject().

🔒 Security Fixes

• Header Injection & Proxy Bypass: Backports v1 security hardening — sanitizes outgoing header values to strip invalid bytes, CRLF sequences, and boundary whitespace (including array values); adds proper NO_PROXY/no_proxy enforcement covering wildcards, explicit ports, loopback aliases (localhost, 127.0.0.1, ::1), bracketed IPv6, and trailing-dot hostnames. Proxy bypass is now checked before the proxy URL is parsed, and parsed.host is used for correct port and IPv6 handling. (#10688)

• CI Security: SHA-pins all actions and disables credential persistence in v0.x CI, introduces zizmor security scanning with SARIF upload to code scanning, adds an OIDC Trusted Publishing workflow with npm provenance attestations, and gates all publishes behind a required npm-publish GitHub Environment with configurable reviewer protections.
