UNDICI PATCHES CHUNKED RESPONSE VALIDATION ACROSS MAJOR VERSIONS

By RepoJournal · Filed · About Node.js

Undici shipped critical fixes for HTTP/1.1 chunked transfer encoding validation in both v6.26.0 and v7.26.0, closing a parsing gap that could affect streaming responses.

Both release lines patched the same vulnerability: validate EOF for chunked h1 responses [2] [3]. The v7 release also backported safe main fixes from the development branch [3], ensuring consistency across the active version tree. On the Node.js core side, WebCrypto spec alignment landed in two complementary PRs covering both nomenclature [5] and systematic regression test coverage [4]. The test suite tightened protections around prototype pollution in cryptographic operations and aligned operation parameters with W3C spec terminology. A streaming regression also shipped: duplex channels now properly handle end() calls after failed endSync() buffering [7], preventing deadlocks when readable side drains queued data. Minor cleanup removed the test-node-output-v8-warning test [6] since asm.js validation is deprecated in V8. Across the ecosystem, semver bumped to 7.8.1 [1] with bug fixes for the npm dependency resolution engine.
