chore(deps): bump undici and @actions/artifact

[dependabot]

Bumps undici to 6.28.0 and updates ancestor dependency @actions/artifact. These dependencies need to be updated together.

Updates undici from 6.24.1 to 6.28.0

Release notes

Sourced from undici's releases.

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.

v6.27.0

⚠️ Security Release

This release line addresses 4 security advisories.

Action required: Upgrade to undici 6.27.0 or later.

npm install undici@^6.27.0

Note on patched version: the v6 fixes shipped in v6.27.0, not 6.26.0 — v6.26.0 contains only the chunked-EOF fix (#5308) and the version bump, none of the security fixes below.

The v6 line is not affected by the SOCKS5 advisories (GHSA-vmh5-mc38-953g, GHSA-hm92-r4w5-c3mj), the shared-cache disclosure (GHSA-pr7r-676h-xcf6), or the 8.x-only WebSocket regression (GHSA-38rv-x7px-6hhq).

Updates @actions/artifact from 4.0.0 to 6.2.1

Changelog

Sourced from @​actions/artifact's changelog.

6.2.1

• Support the RFC 5987 filename* field in the content-disposition header. This allows us to correctly download files and artifacts with Chinese/Japanese/Korean (among other) characters in their name.

6.2.0

• Support uploading single un-archived files (not zipped). Direct uploads are only supported for artifacts version 7+ (based on the major version of actions/upload-artifact). Callers must pass the skipArchive option to uploadArtifact. Only single files can be uploaded at a time right now. Default behavior should remain unchanged if skipArchive = false. When skipArchive = true, the name of the file is used as the name of the artifact for consistency with the downloads: you upload artifact.txt, you download artifact.txt.

6.1.0

• Support downloading non-zip artifacts. Zipped artifacts will be decompressed automatically (with an optional override). Un-zipped artifacts will be downloaded as-is.

6.0.0

• Breaking change: Package is now ESM-only
  • CommonJS consumers must use dynamic import() instead of require()

5.0.3

• Bump @actions/http-client to 3.0.2

5.0.1

• Fix Node.js 24 punycode deprecation warning by updating @azure/storage-blob from ^12.15.0 to ^12.29.1 #2211
• Removed direct @azure/core-http dependency (now uses @azure/core-rest-pipeline via storage-blob)

5.0.0

• Dependency updates for Node.js 24 runtime support
• Update @actions/core to v2
• Update @actions/http-client to v3
