fix(deps): clear the Docker CVEs no version bump could ever reach - #135
Conversation
github.com/docker/docker stops at v28.5.2+incompatible. Engine 29.x exists, but moby tags those releases docker-v29.x.y, which is not a semver tag, so the module proxy cannot serve them: go get github.com/docker/docker@v29.3.1 +incompatible fails with "unknown revision". That is why GitHub reports no fixed version for the four open Docker advisories. There will not be one. moby split the client into github.com/moby/moby/client, which carries no daemon code at all, so the daemon CVEs leave the tree with the module rather than with a patch release. This ports internal/runtime to that client's options-in/result-out API and takes echo to 4.15.3 for the encoded-slash static-file bypass. govulncheck goes back to a hard gate. It exits 3 on main today and 0 here, so the job can still go red, which was the whole point of the escape hatch.
📝 WalkthroughWalkthroughThe runtime migrates Docker API usage to Moby client packages. Tests and dependencies follow the new APIs. Port validation and statistics handling are updated. CI now fails when govulncheck finds a reachable vulnerability. ChangesDocker Moby migration

docs/SECURITY-NOTES.md said the workflows build with the latest 1.26.x so each Go security release arrives on its own. They did not. All three jobs pinned go-version: '1.26.5', and go1.26.6 fixes five stdlib advisories our code calls: GO-2026-6218 net/url, GO-2026-6090 crypto/tls, GO-2026-6089 and GO-2026-5026 net/http, GO-2026-5972 encoding/asn1. The release job had the same pin, so shipped desktop binaries carried them too. Asking for '1.26' lets setup-go resolve the newest patch and makes the doc true. govulncheck exits 3 under go1.26.5 and 0 under go1.26.6.
Every Docker call in internal/runtime was rewritten for the moby client and only the stats path had a test behind it. A wrong-but-compiling option struct (a filter that matches nothing, an inspect reading the wrong field) would have shipped silently. TestDockerProviderLifecycleIntegration deploys, lists, reads logs, stops, starts, restarts and removes a throwaway container, then checks it is gone. It skips when no daemon is reachable, and adopts the docker CLI's current context when the default socket is not the live one. The probe traps SIGTERM, so Stop and Restart return at once rather than burning the 20s timeout twice: the test runs in 3s, not 45s. TestBuildPortsParsesAndRejects covers buildPorts, which had no test and now has an error path. internal/runtime coverage goes from 73.6% to 89.6%.
…ss container buildPorts skipped any entry that was not exactly host:container, so a service definition with "8080" instead of "8080:8080" deployed cleanly and published nothing. Nobody finds that until they try to reach the service. The schema is ports: ["port:port"] and every catalog entry already matches, so rejecting the rest costs nothing and turns a silent misconfiguration into a failed deploy with the offending string in the error.
…s image desktop-release.yml runs go test on windows-latest, where Docker is up but serving Windows containers. Status() pings fine there, so the test would get past its daemon check and then fail pulling a Linux busybox, breaking every release build. Pulling before the deploy turns that into a skip, which is what the existing stats integration test already does.

Triaging the one remaining pre-merge check, Docstring Coverage 60% vs 80%: leaving it, deliberately. Of the ten functions it scored, this diff touches For the record, the merge-risk banner at the top of this PR is stale rather than outstanding. It is pinned to Also confirmed the govulncheck gate is genuinely a gate now, not a relabelled advisory — |
#135 loosened go-version from '1.26.5' to '1.26' so setup-go would track the latest 1.26.x and pick up stdlib security releases automatically. That trades reproducibility for convenience: a release rebuilt later may compile with a different toolchain than the one that shipped. Pin the exact patch in all three places (ci.yml twice, desktop-release.yml once). 1.26.8 is the current 1.26.x, two patches past the 1.26.6 that #135's control run resolved, so this is not a rollback to a vulnerable toolchain. The govulncheck hard gate is what stops an exact pin from rotting: it runs on the pinned toolchain, so a reachable stdlib advisory fails CI on the next PR and prompts a bump. SECURITY-NOTES.md now describes that policy instead of the floating one.

github.com/docker/dockerstops atv28.5.2+incompatible, from November 2025. Engine 29.x exists, but moby tags those releasesdocker-v29.x.y, and that is not a semver tag, so the module proxy cannot serve them:The daemon moved to
github.com/moby/moby/v2, which contains no client package at all, and the client split out intogithub.com/moby/moby/client. The fix is the module move, not a version bump.What this does
internal/runtimenow talks to the daemon throughgithub.com/moby/moby/clientand its types modulegithub.com/moby/moby/api.github.com/docker/dockeris gone fromgo.mod, and five other modules go with it, because that one module shipped the daemon and the client together and we only ever act as a client.github.com/labstack/echo/v4goes to 4.15.3 for the encoded-slash static-file bypass, which closes the fifth alert.Closes alerts #1, #3, #4, #5 and #23.
govulncheckgoes back to a hard gate. It had been advisory since the accepted-CVE list went in, which made it a check that could not fail.The Go pin the gate caught straight away
Turning the gate on failed the build, and not because of the SDK move.

Every Docker call here was rewritten and only the stats path had a test behind it, so a wrong-but-compiling option struct would have shipped in silence.
TestDockerProviderLifecycleIntegrationdeploys, lists, reads logs, stops, starts, restarts and removes a throwaway container against a live daemon, then checks it is gone. Point its label filter at a label that matches nothing and it fails on the List assertion, so it is a check that can go red.It runs in about 3 seconds. The probe traps SIGTERM, because PID 1 ignores signals it has no handler for and a bare
sleepwould sit through Stop's SIGTERM and cost the 20 second timeout twice.Worth a second look
buildPortsnow returns an error for a malformed port mapping.network.Portis a parsed value where the oldnat.Portwas a raw string handed straight to the daemon. The only port mapping in the catalog is"4449:4449", which parses, andTestBuildPortsParsesAndRejectscovers both sides.WithAPIVersionNegotiation()is a deprecated no-op in the new client, so it is gone.
