GHSA-2v4p-qf9q-27wj is a panic in gRPC-Go's xDS routing interceptor: a
request arriving with neither `:authority` nor `Host` indexes an empty
slice, the per-RPC goroutine does not recover, and the process dies.
High, and nine alerts, because nine go.mod files pin the same version --
eight directly, terraform indirectly.
Nothing here was reachable. The interceptor is installed by
`xds.NewGRPCServer`, which this repo never calls: the one production
server is `grpc.NewServer(grpc.Creds(...))` in ingest/internal/grpcserver
and the only other is a plain one in a searchclient test. That is also
why security-scan has been green throughout -- govulncheck reports on
reachability and found nothing on 1.83.1, while Dependabot reports on
version ranges and found nine. Both were right.
Taken anyway: it is a patch release, and the next advisory in this
dependency may well land somewhere we do reach.
`go mod tidy` carried the indirect requirements grpc 1.83.2 asks for --
x/net, x/text, x/sys and friends. No CI job builds or tests Go here, so
all nine modules were built locally and api, ingest and enterprise
tested with -count=1, since a cached pass would not have exercised the
new version.
The dependabot.yml is the other half. There was no config, so nothing
opened a PR against any of this. Go majors stay out of the group, being
import path changes rather than bumps.
Dependabot alerts were switched on for this repo today and reported 12 open
findings. Ten are fixed here; the other two are addressed below.
gRPC 1.83.0 -> 1.83.1, in all nine modules that require it. This is
GHSA-vp52-pcj8-j9qc / CVE-2026-84304, heap memory exhaustion via HTTP/2 DATA
frame fragmentation, affecting <= 1.83.0. It matters more than the version
delta suggests: ingest/ is a gRPC listener deliberately exposed to the internet
on :4317, so a remote OOM is reachable. mTLS narrows that to holders of a
client certificate, which is why this was not an emergency, but the fix is one
patch release away and there is no reason to carry it.
golang.org/x/oauth2 0.21.0 -> 0.27.0 in deploy/operator, an indirect
dependency (GHSA-6v2p-p543-phr9). enterprise/ was already past it at 0.36.0.
npm cookie 0.6.0 -> 0.7.2, via an overrides entry rather than a dependency
bump. @sveltejs/kit requires ^0.6.0 and still does at 2.70.3, the latest
release, so there is no version of kit that resolves this on its own -- an
override is the only route that does not involve waiting on upstream.
Three incidental changes came out of `go mod tidy` and are not mine:
genproto/googleapis/rpc moved forward as a transitive of the new grpc; pgx/v5
was reclassified from indirect to direct in enterprise/, which is simply
correct, since audit.go and cmd/enterprise-auth import it; and the proto
replace directive shuffled between require blocks at the same version.
The twelfth finding, lru (GHSA-rhfx-m35p-ff5j), is not fixed and is not
fixable here -- see the note in the pull request. It is CVSS 0, a Stacked
Borrows soundness issue in IterMut, and reaching a patched version means
tantivy 0.22 -> 0.26, which is a search engine migration rather than a
dependency bump.
Verified: all ten Go modules build, 40 test packages pass, the web app builds
and svelte-check reports 0 errors across 288 files.
Pushes synthetic cairnobs.metrics/cairnobs.heartbeat-tagged records
straight to ingest so a demo deployment's Hosts page and per-host detail
page have CPU/memory/disk to show. Neither benchmark-fixture nor
windows-fixture emits those two attributes -- only the real agent does
-- so nothing else could populate that page.
Superseded by /hack/demo-simulator in the next commit, which covers the
same records as part of a whole fleet; kept because it is still the
smallest thing that fills the Hosts page on its own.
