chore(deps): bump axios from 0.21.0 to 0.33.0 in /docs/multiple-tests/pattern-vulnerability-high/src/javascript

[dependabot]

Bumps axios from 0.21.0 to 0.33.0.

Release notes

Sourced from axios's releases.

v0.33.0 — June 13, 2026

This release hardens request config handling and form serialisation, adds Node.js 26 coverage for v0.x, and updates the v0.x release workflow.

🔒 Security Fixes

• Request Config Hardening: Uses own-property reads for nested request options affecting auth, params, proxy, and data handling; adds bounded form serialisation depth checks; normalises nullish Basic Auth credentials; and treats 0.0.0.0 as local for proxy bypass. (#11001)

🚀 New Features

• Node.js 26: Adds Node.js 26 to the v0.x CI and release/publish matrices. (#10937)

🔧 Maintenance & Chores

• Release Publishing: Adopts npm staged publishing for v0.x releases and disables npm caching in CI to make installs and publish jobs more deterministic. (#10936, #10943)
• Changelog: Backfills missing v0.x changelog entries for prior releases. (#10842)
• Release Metadata: Bumps package and internal version metadata for v0.33.0. (#11002)

Full Changelog

v0.32.0 — May 4, 2026

This release backports a comprehensive set of security and hardening fixes from the v1.x branch into v0.x, covering prototype-pollution protections, default error redaction, stricter proxy/cookie/socket handling, and one breaking change to merged config and header object prototypes.

⚠️ Breaking Changes & Deprecations

• Null-prototype merged objects: mergeConfig and header merging now return objects with a null prototype to block prototype-pollution gadgets. Consumers must use Object.prototype.hasOwnProperty.call(obj, key) and avoid implicit string coercion against merged config or header objects. (#10838)

🔒 Security Fixes

• Default error redaction: AxiosError.toJSON() now redacts sensitive keys by default to prevent credential leaks in logs. The behavior is configurable via config.redact, with defaults exposed on defaults.redact. (#10838)
• Cookie & XSRF handling: Cookie names are read literally rather than via regex, and only own properties are respected when evaluating withXSRFToken. (#10838)
• Proxy bypass IPv6 parity: NO_PROXY matching now handles canonical IPv4-mapped IPv6 forms such as ::ffff:127.0.0.1 and ::ffff:7f00:1. (#10838)
• Node http adapter hardening: Strips Proxy-Authorization when no proxy is in use and gates socketPath behind a new allowedSocketPaths allowlist (string or array, normalized) to reduce accidental Unix socket exposure. (#10838)
• Browser xhr adapter: Stricter own-property checks when reading config and headers. (#10838)
• URL parameters: AxiosURLSearchParams keeps %00 encoded and applies consistent encoding throughout. (#10838)
• Public type surface: Adds formDataHeaderPolicy, redact, and allowedSocketPaths to the TypeScript declarations alongside their runtime defaults. (#10838)

🔧 Maintenance & Chores

• Repo hygiene: Updates README.md and CHANGELOG.md, adds AGENTS.md, and refreshes the issue and PR templates. (#10838)

Full Changelog

v0.31.1

This release backports a broad set of security hardenings from the v1 line — covering prototype-pollution defences, stream size enforcement, XSRF handling, URL null-byte encoding, and bounded FormData recursion — and drops committed dist/ artefacts along with Bower support.

⚠️ Breaking Changes & Deprecations

• Bower & Committed dist/ Removed: dist/ bundles are no longer committed to the repo, and bower.json plus the Grunt package2bower task have been removed. CI still builds bundles before publish, so npm/yarn/pnpm consumers are unaffected; installs via Bower or directly from the git tree must migrate to npm or a CDN. (#10747)

Pull Request Overview

This PR upgrades the axios dependency from version 0.21.0 to 0.33.0. While this update provides security hardening and enhanced Node.js support, it includes a critical breaking change introduced in Axios v0.32.0: merged configuration and header objects now utilize a null prototype to prevent prototype-pollution gadgets.

Direct calls to .hasOwnProperty() on these objects will throw runtime errors. Although the PR is marked as up to standards by Codacy, there is no evidence of automated tests or verification logic to ensure the application correctly handles these modified object structures or the new default redaction behavior in AxiosError.toJSON().

About this PR

• The PR contains no automated tests or evidence of verification to ensure the breaking changes do not impact the current application logic.
• The upgrade includes a breaking change from v0.32.0 where merged config and header objects have a null prototype, which can cause runtime errors if the application calls methods like '.hasOwnProperty()' directly on them.

[REDACTED:HIGH_ENTROPY]

_{line 6 🟡 MEDIUM RISK}
Suggestion: Axios 0.32.0 introduced a breaking change where merged config and header objects now have a null prototype. Ensure the codebase uses 'Object.prototype.hasOwnProperty.call(obj, key)' instead of 'obj.hasOwnProperty(key)' for any logic handling these objects.

Test suggestions

• Verify application functionality after the axios upgrade, specifically checking for usage of merged config or header objects affected by the null-prototype breaking change in v0.32.0.
• Verify that sensitive information is correctly redacted in AxiosError.toJSON() as per the new default behavior introduced in v0.32.0.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify application functionality after the axios upgrade, specifically checking for usage of merged config or header objects affected by the null-prototype breaking change in v0.32.0.
2. Verify that sensitive information is correctly redacted in AxiosError.toJSON() as per the new default behavior introduced in v0.32.0.
