Bumps the npm_and_yarn group with 1 update in the / directory: undici.

Updates undici from 7.29.0 to 7.29.1

Release notes

Sourced from undici's releases.

v7.29.1

⚠️ Security fixes

High severity

  • GHSA-w293-vg96-wgc3: BalancedPool could drop function-valued connection options while cloning its configuration, including custom TLS certificate validation callbacks. Undici now preserves connect and legacy tls options when creating upstreams. Fixed by f690157d.
  • 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 6615e017.

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 63cf698b.
  • GHSA-rx4f-c7p8-82vq: an unclean WebSocketStream close could create an unobserved rejected promise when its writable stream was locked, potentially terminating the process. Undici now propagates the failure through the retained writable stream controller. Fixed by 1858656e.
  • GHSA-2jfj-6hjv-fm6j: shared caches could store and replay responses containing Set-Cookie, disclosing one user's cookies to another caller. Undici now excludes these responses from shared caches, including existing entries and revalidation paths. Fixed by b6c5a002.
  • GHSA-3xpg-4rpp-hhhm: the decompression interceptor did not bound decoded output, allowing compressed responses to consume excessive memory. Undici now limits every decompression stage to 64 MiB by default and supports a configurable maxSize. Fixed by 2c7d7e12.
  • GHSA-pmjh-fq2x-6v4x: a terminal retry failure after response headers were exposed could orphan the original response body, causing consumers to hang indefinitely. Undici now propagates the terminal error to the exposed body. Fixed by 3c672659.

Low severity

  • GHSA-8436-99hf-9mmv: cache interceptors could store and replay responses to unsafe HTTP methods such as POST or DELETE. Undici now restricts cache reads and writes to safe methods while preserving invalidation by successful unsafe requests. Fixed by b61d9432.
  • GHSA-2gqq-gqf2-x968: the dump interceptor could treat an oversized chunked response as successfully truncated when no Content-Length was present. Undici now enforces maxSize against received bytes and aborts oversized responses. Fixed by 21693f40.
  • 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 cd8af90b.
