The dev server shipped two entries, index and serve-entry, bundled
independently because the publish build set splitting:false. They share
pipeline.ts, which holds mutable module state -- compileCacheDir, set once
at startup by the bootstrap, and browserArtifactPaths, populated during
compilation and read when serving /__wrnexus/client/*. Duplicating the
module duplicated the state, so the writer and the reader addressed
different copies: every component client module 404'd and .wrn compilation
wrote nothing. It works from source, where there is one module instance,
which is why it reached a release. Emitting a shared chunk fixes it for
every package at once.
resetDevCache also ran several hundred lines after the plugin virtual
modules were written into the same directory, deleting them at every boot.
An app with no plugins never noticed; an app with one lost them every time.
Separately, secureCookieOptions spread ...options after its path default,
and setSecureCookie always forwards an explicit path key -- so omitting
path emitted a cookie with no Path at all, which the browser then scoped to
the request's directory.
Verified end to end against a real app installing the published packages:
17 artifacts written, client modules 200, and the sign-in form submits from
the UI and reaches /dashboard.

Audit of 0.8.4 found the repo's own gates green, so these came from manual
review; each is covered by a new regression test.
security/fetch.ts
- safeFetch re-attached Authorization/Cookie on a same-origin redirect that
followed a cross-origin hop (a -> b -> b), handing credentials to the second
host. Compare against the origin the caller trusted, not the previous hop.
- The private-network guard resolved the host, approved it, then let fetch
resolve again, so a low-TTL record could answer public for the check and
private for the connection. Pin the connection to the validated address,
preserving Host and TLS serverName. Opt out with pinDns: false.
- 0:0:0:0:0:ffff:127.0.0.1, ::ffff:7f00:1 and fec0::1 were not treated as
private. Add uncompressed IPv4-mapped forms, site-local IPv6, 198.18/15
and 192.0.0/24.
security/url.ts
- sanitizeUrl returned "//evil.com" verbatim via the relative-path fast path,
bypassing the host checks it had just run; in an href that navigates
cross-origin. Resolve protocol-relative input instead.
dev-server/gateway.ts
- Malformed base64 in an Authorization header threw out of checkAuth on an
unauthenticated path. Fail closed.
- split(":", 2) truncated passwords at the first colon, so a password
containing ":" could never authenticate.
- The credential compare short-circuited on length mismatch, leaking length
by timing. Extracted as verifyBasicAuth so it is testable.
authz/index.ts
- Namespace wildcards only matched the first segment, so "post:comment:*"
did not grant "post:comment:delete". Match at every depth.
uploader/operations.ts
- Validate transcoder dimensions and bitrate rather than trusting the declared
type, and reject ".." path segments.
package.json
- The brace-expansion override pinned 5.0.8, which is inside the advisory
range >=4.0.0 <5.0.9. Bump to 5.0.9; bun audit is now clean.
Verified: check:production passes (typecheck, lint, 1033 tests, format,
ASVS, public-API baseline, editor checks).
