govulncheck on the pinned 1.26.8 toolchain reports twelve reachable
standard library vulnerabilities in Pulse (net/http, crypto/tls,
html/template, os, net/textproto), published on 2026-10-08 and fixed in
Go 1.26.9. golang.org/x/net v0.58.0 carries further advisories fixed in
v0.60.0. With 1.26.9 and x/net v0.60.0 the scan reports no affecting
vulnerabilities under both govulncheck v1.1.4 and v1.7.0.
Pulse's own govulncheck job last ran on 2026-10-05, so nothing flagged
this. The private Enterprise build and test job notices it: once the scan
finds reachable advisories it needs more than the 4 GiB CI VM holds, the
guest kernel kills govulncheck, and the job is cancelled. That has failed
every Enterprise pair check since 2026-10-08, including the first
beta's.
Move every release builder and local toolchain guard together, as 1.26.8
did, so no candidate artifact keeps an older compiler: go.mod, the
builder image digests (index digest for 1.26.9-alpine), the release and
dev scripts, the devcontainer, and the root pair diagnostic. Only x/net
is raised in the module graph; go mod tidy is deliberately not run, so
unrelated indirect requirements stay as they were.
Contract-Neutral: Toolchain and indirect dependency patch update that clears reported advisories; no product or runtime contract changed.
Go 1.26.8 supersedes the prior patch release, so every release builder and local toolchain guard must move together to prevent candidate artifacts from retaining an older compiler and runtime.
Contract-Neutral: toolchain-only patch update; no product or runtime contract changed
