v6.28.1

⚠️ Security fixes

High severity

• GHSA-rfgv-xxqx-mfg5: a WebSocket server could select a subprotocol when none was requested, causing an uncaught TypeError that could terminate the process. Undici now rejects the handshake with protocol error 1002. Fixed by 2af0faf8.

Medium severity

• GHSA-3wwx-pv8p-q78v: a malformed permessage-deflate payload exceeding the configured decompression limit could emit an unhandled zlib error and terminate the process. Undici now destroys the inflater after reaching the limit. Fixed by 07c60d9c.

Low severity

• GHSA-r53p-7pc4-xj5r: the retry interceptor could concatenate a resumed response with inconsistent framing into downstream output, enabling response splitting or corruption. Undici now validates Content-Range against the original response framing before resuming. Fixed by ce31bc82.

What's Changed

• perf: reduce EventSourceStream parser allocations (#5032) by @​mcollina in nodejs/undici#5647
• [v6.x] perf(h1): drop idle-socket timer floor with a ref'd setImmediate (#5707) by @​mcollina in nodejs/undici#5770

v6.28.0

⚠️ Security fixes

• GHSA-m8rv-5g2x-5cg5: a malicious type property on a duck-typed blob-like HTTP/1.1 request body could inject CRLF sequences into the generated content-type header. Undici now coerces and validates the value before adding it to the request. Fixed by 740a0b7c.
• GHSA-8xcm-r25x-g524: the retry interceptor could expose a stale Content-Length after resuming a partial response, potentially causing downstream response desynchronization, hangs, or corruption. Undici now rejects partial responses whose Content-Length is inconsistent with Content-Range. Fixed by cba3a52a, with corrected fixtures in 4fd5a0c6.
• GHSA-v3r7-h72x-cjcm: unsanitized domain and unparsed values passed to setCookie() could inject cookie attributes. Undici now validates cookie domains, paths, and unparsed attributes more strictly. Fixed by af748404.

GHSA-4cwx-7wf7-3272 and GHSA-jr45-8vmc-qm54 affect the cache interceptor in Undici v7 and v8; Undici v6 is not in their affected version ranges.
