fix(build): bump Dockerfile.exec Go toolchain to 1.26.5#32
Merged
Conversation
The released zip binaries are built by Dockerfile.exec (via the onDemandPublishToAWS workflow), which still pinned golang:1.26.3-alpine3.23 - PR 31 updated only the main Dockerfile. As a result the published 26.07.1 binaries embed stdlib go1.26.3, which carries CVE-2026-42504 and CVE-2026-39822 (both HIGH) and trips consumers' vulnerability gates (rejected the rearm-watcher release). Align Dockerfile.exec to the same golang:1.26.5-alpine3.24 digest as the main Dockerfile. OSV reports zero stdlib vulns for 1.26.5. Verified by building Dockerfile.exec locally: the produced linux-amd64 binary embeds go1.26.5 and x/net v0.57.0.

Why
The published 26.07.1 zip binaries embed stdlib go1.26.3, which carries CVE-2026-42504 and CVE-2026-39822 (both HIGH) — these just tripped the critical/high gate on the rearm-watcher release that bundles the CLI.
Root cause: the zips are built by
Dockerfile.exec(viaonDemandPublishToAWS.yml), which still pinnedgolang:1.26.3-alpine3.23. #31 updated only the mainDockerfile— the second builder was missed.What
One line: align
Dockerfile.execto the samegolang:1.26.5-alpine3.24pinned digest as the main Dockerfile. OSV reports zero stdlib vulnerabilities for go 1.26.5 (current latest stable).Testing
Built
Dockerfile.execlocally (full multi-platform zip matrix) and inspected the produced linux-amd64 binary:go version -m→ go1.26.5,golang.org/x/net v0.57.0A new CLI release from this will clear the two stdlib HIGHs on consumer images; the remaining watcher-release blockers (kubectl-embedded x/net critical, Alpine openssl FPs) are separate tracks.
