velero-io/velero: technical due diligence, read from its repository

The median source file here is 126 lines. 3 files exceed 1,260 lines, the largest being 3,257. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

11 files were marked deprecated over two years ago and still are, the oldest since Aug 2022. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

The newest release, v1.18.4, is not on the branch this survey read; the newest release on it is v1.6.0. The shipped product may differ from what this report describes. Survey the release branch too.

6 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

4 workload manifests set no CPU or memory limits. One pod that leaks memory or spins can starve everything else on its node, and the scheduler cannot plan capacity for what it cannot see.

The newest was published on 2026-09-28. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 2 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 1.6.0. Answer lives in: the release you run, set against each fixed version. GHSA-j2g6-362q-6qc6 (moderate) is fixed in the surveyed commit; which release carries it cannot be told from this history, which does not place the release users run. Answer lives in: the version you run. The record is incomplete: NVD: 1 record names velero with nothing tying it to this repository (CVE-2020-3996).

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

3 images in the deployment configuration are named without a version or as `latest`. A redeploy can change the software without a commit, a rollback has nothing to roll back to, and nobody can say from the repository what is running.
