0.8.15

Commits

Fixed

• Security: parsing a deeply or repeatedly namespaced document no longer consumes quadratic memory; the in-scope namespace map is inherited through the prototype chain instead of being copied for every prefix-declaring element (O(N) instead of O(N²)), preventing a denial-of-service reachable from DOMParser.parseFromString with default options. Serialized output is byte-identical. GHSA-965w-775f-mr7g
• Security: attribute de-duplication during parsing is now O(M) instead of O(M²); the NamedNodeMap parse-time dedup path uses a null-prototype membership index, so a well-formed document with a hostile number of duplicate attributes can no longer wedge the parse. Attribute order and duplicate resolution (last value wins, first position kept) are byte-identical, preserving the XML no-duplicate-attributes well-formedness constraint. GHSA-8344-3jmq-59r6
• Security: trimming trailing whitespace from an XML end tag (ETag) is now anchored so it runs in linear time instead of backtracking quadratically on a long whitespace run, preventing a ReDoS reachable from DOMParser.parseFromString. Trimmed output is byte-identical. GHSA-x4fp-j954-r2f4
• Security: malformed-input recovery is now linear instead of quadratic — the malformed tag-name scan terminates at an embedded <, and Node.prototype.normalize() merges adjacent text nodes in O(K) instead of O(K²) (also reachable programmatically), per normalize() in the WHATWG DOM spec. DOM output is unchanged; only the reported error text differs. GHSA-93r5-fhx6-vmg9
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now rejects a DocType name that is not a valid XML Name, throwing InvalidStateError — matching the sibling publicId/systemId/internalSubset checks and preventing XML injection via DocumentType.name. GHSA-27p8-2357-5qqv
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — a check 0.8.x did not previously perform, preventing PI-target injection via >, ?, or whitespace. GHSA-c7q8-3ch8-vqpv
• Security: Document.createEntityReference() now rejects an invalid XML Name at creation, and XMLSerializer.serializeToString() under { requireWellFormed: true } validates an EntityReference nodeName as an XML Name, throwing InvalidStateError — preventing XML injection via an entity-reference name. GHSA-6gmq-8vp8-gcm6
• Security: the parser now reports a not-well-formed end tag whose valid name is followed by trailing content as a recoverable error instead of accepting it silently, per the XML ETag production; parsing recovers to the byte-identical DOM. Consumers that want strict rejection can escalate the reported error to fatal via the parser's errorHandler. GHSA-6h8r-xr42-gp59

Thank you, @​ericchiang, @​bhaswanthc, @​arpitjain099, @​Paranoidgrinch, for your contributions

0.8.14

Commits

Fixed

• Security: XMLSerializer.serializeToString() now also rejects invalid element and attribute names when { requireWellFormed: true } is passed, throwing InvalidStateError for a name that is not a valid XML QName (this covers the namespace prefix, which surfaces in the element qualified name or in a synthesized xmlns: declaration). This prevents XML injection via createElement() / setAttribute(), extending the existing requireWellFormed checks to the serialized name set. GHSA-w2rr-34g9-rvrj GHSA-4w3w-2rp5-g8jm

Thank you, @​bhaswanthc, @​jmestwa-coder, for your contributions

0.8.13

Commits

Fixed

• Security: XMLSerializer.serializeToString() (and Node.toString(), NodeList.toString()) now accept a requireWellFormed option (fourth argument, after isHtml and nodeFilter). When { requireWellFormed: true } is passed, the serializer throws InvalidStateError for injection-prone node content, preventing XML injection via attacker-controlled node data. GHSA-j759-j44w-7fr8 GHSA-x6wf-f3px-wcqx GHSA-f6ww-3ggp-fr8h
  • Comment: throws when data contains -->
  • ProcessingInstruction: throws when data contains ?>
  • DocumentType: throws when publicId fails PubidLiteral, systemId fails SystemLiteral, or internalSubset contains ]>
• Security: DOM traversal operations (XMLSerializer.serializeToString(), Node.prototype.normalize(), Node.prototype.cloneNode(true), Document.prototype.importNode(node, true), node.textContent getter, getElementsByTagName() / getElementsByTagNameNS() / getElementsByClassName() / getElementById()) are now iterative. Previously, deeply nested DOM trees would exhaust the JavaScript call stack and throw an unrecoverable RangeError. GHSA-2v35-w6hq-6mfw

Maintainer changes

This version was pushed to npm by karfau, a new releaser for @​xmldom/xmldom since your current version.

Updates axios from 1.9.0 to 1.20.0

Release notes

Sourced from axios's releases.

v1.20.0 — August 19, 2026

This release hardens runtime option handling, adds RFC 9110 status-code aliases, fixes Node.js and XHR reliability issues, and refreshes project tooling and documentation.

⚠️ Breaking Changes & Deprecations

• HTTP Status Naming: Added ContentTooLarge (413) and UnprocessableContent (422), while retaining PayloadTooLarge and UnprocessableEntity as backward-compatible deprecated aliases. (#11082)

🔒 Security Fixes

• Runtime Option Handling: Hardened behavioral configuration reads against shared and foreign prototype pollution and normalized unsafe interceptor replacement objects. This also clarifies Fetch redirect and custom implementation behavior, HTTP/2 DNS and proxy handling, CIDR-based NO_PROXY matching, and malformed data URI rejection; see the PR for documented compatibility effects. (#11141)

🐛 Bug Fixes

• Interceptor Lifecycle: Prevented unbounded handler-array growth by trimming trailing ejected interceptors without changing iteration semantics, and kept interceptor operations safe when the public handlers field is nullish. (#11087, #11118)
• Request Error Preservation: Prevented custom Error.prepareStackTrace implementations that return non-string values from replacing the original request failure with an unrelated TypeError. (#11109)
• XHR Reliability: Navigation-canceled requests now reject with ECONNABORTED instead of resolving with status 0, while successful downloads flush their final progress callback during the live loadend dispatch. (#11094, #11121)
• Node.js Socket Memory: Removed request-context retention from per-socket error listeners, preventing completed response data from being pinned for the lifetime of pooled keep-alive sockets. (#11091)
• Core Methods and HTTP Errors: Prevented structural method-header buckets from leaking into outgoing headers, standardized invalid DNS lookup and httpVersion failures as AxiosError.ERR_BAD_OPTION_VALUE, and corrected the timeoutErrorMessage merge strategy. (#11096)

🔧 Maintenance & Chores

• Dependencies: Updated fast-uri, postcss, js-yaml, mocha, development-tooling groups, and GitHub Actions dependencies. (#11092, #11098, #11099, #11106, #11107, #11122, #11123, #11126, #11127, #11133, #11140, #11143, #11144)
• Documentation: Applied the v1.19.0 documentation updates, added the missing fs import to the README stream example, introduced localized global search, and repaired the interceptor test link. (#11101, #11113, #11097, #11119)
• Sponsorship: Updated sponsorship links and data and added ScrapingBee as a sponsor. (#11124, #11136, #11137)
• CI and Release: Switched ESM smoke tests to locked dependencies and synchronized package and runtime version metadata for v1.20.0. (#11128, #11152)

Full Changelog (axios/axios@v1.19.0...v1.20.0)

v1.19.0 - July 22, 2026

This release raises the form-data security floor, adds configuration and type-system capabilities, and fixes NO_PROXY matching, interceptor errors, progress reporting, and serialization edge cases.

🔒 Security Fixes

• Multipart Form Data: Raised the form-data dependency floor to ^4.0.6, preventing fresh installations from resolving versions affected by the CRLF injection vulnerability GHSA-hmw2-7cc7-3qxx (GHSA-hmw2-7cc7-3qxx). (#11028)

Changelog

v1.19.0 — July 22, 2026

This release raises the form-data security floor, adds configuration and type-system capabilities, and fixes NO_PROXY matching, interceptor errors, progress reporting, and serialization edge cases.

🔒 Security Fixes

• Multipart Form Data: Raised the form-data dependency floor to ^4.0.6, preventing fresh installations from resolving versions affected by the CRLF injection vulnerability GHSA-hmw2-7cc7-3qxx (GHSA-hmw2-7cc7-3qxx). (#11028)

🚀 New Features

• Configuration Extensibility: Preserved own-enumerable symbol-keyed fields through mergeConfig and added a generic params type across public TypeScript declarations, responses, errors, adapters, and serializers. (#11043, #11081)
• Header Parameter Parsing: Added the opt-in AxiosHeaders.parseParameters() parser for quote-aware, RFC-style HTTP parameter parsing while preserving legacy parsing behavior. (#11051)
• HTTP Status Codes: Added the missing Cloudflare 520 WebServerReturnsAnUnknownError status and matching ESM/CJS declarations. (#11067)

🐛 Bug Fixes

• Form Data Conversion: Limited formDataToJSON path splitting to dot and bracket notation, preserving literal punctuation in keys, and removed browser-facing Buffer.from usage from toFormData to avoid unnecessary polyfills. (#11006, #11018)

• Proxy Bypass: Canonicalized IPv4 shorthand, octal, and hexadecimal forms during NO_PROXY matching and honored * entries within comma- or space-separated bypass lists. (#11029, #11053)

• Cancellation: Propagated already-aborted input signals immediately when composing abort signals. (#11035)

• Header Handling: Preserved empty first values for duplicate singleton headers and made AxiosHeaders#getSetCookie() consistently return arrays for present values. (#11036, #11037)

• URL Handling: Included normalized, safely redacted offending URLs in malformed-protocol errors and removed repeated trailing slashes when combining base URLs. (#11008, #11038)

• Progress Events: Clamped malformed negative progress values to zero and ensured final Node.js download progress events are delivered before streamed responses close. (#11039, #11040)

• Error and JSON Serialization: Serialized Set values as arrays in JSON-compatible snapshots and synthesized useful AxiosError messages from otherwise-empty AggregateError instances. (#11044, #11059)

• Content-Length Enforcement: Corrected base64 data: URL size estimation so maxContentLength is enforced consistently by the HTTP and Fetch adapters. (#11061)

• Synchronous Interceptors: Prevented requests from being dispatched after synchronous request interceptors fail unless their paired rejection handler resolves successfully. (#11071)

🔧 Maintenance & Chores

• Dependencies: Updated development and test tooling, the docs fixture's Axios version, and GitHub Actions integrations including Checkout, Setup Node, Setup Deno, and Zizmor. (#11031, #11055, #11056, #11058, #11079, #11080, #11088, #11089, #11090)
• Build Outputs: Limited sourcemap generation to published minified bundles, removing broken map references from non-minified builds. (#11054)
• Form Data Internals: Centralized FormData header handling and made the Node.js adapter tolerate getHeaders() returning undefined under the content-only policy. (#11062)
• Developer Experience: Ignored common local AI-tooling directories and fixed a constant-reassignment crash when the development sandbox serves its root path. (#11032, #11073)
• Documentation: Updated sponsor information, clarified that baseURL is not a path-security boundary, scoped provenance claims to attested releases, and corrected the configuration-defaults documentation. (#11041, #11068, #11076, #11078)
• Publishing: Simplified v1 publishing to use the npm version bundled with Node.js 26 and updated package metadata for the 1.19.0 release. (#11083, #11095)
