getsentry/self-hosted: technical due diligence, read from its repository

Five files out of 223 absorb 34% of all file-level change. Concentration like this is where debt is usually being serviced rather than repaid: the same code is reopened because it is load-bearing, fragile, or both. A repository cannot tell you which — that is a conversation with the team.

.env, optional-modifications/patches/external-kafka/.env.patch are tracked in git. Environment files are where credentials usually live, and committing one usually means nobody decided how secrets reach the running application. Whatever is in it is in the history for good. Check 05.1 says whether it holds anything credential-shaped.

4 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.

2 HTTP calls use a client with no timeout (Python `requests` without `timeout=`, or Go's default client). When a dependency slows down, each one holds a worker until the connection gives up, and enough of them take the service down with the dependency.

3 of 46 locked dependencies match 7 published advisories in OSV, 4 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. None of the high or critical ones is in what the product ships: they are development dependencies.

LICENSE.md grants FSL-1.1-ALv2: source available, not open source; a competing commercial product or service is not allowed; each version becomes Apache-2.0 two years after its release. The reading comes from the licence's own title and clauses. Whether the terms fit the buyer's intended use, and whether any paid licence transfers with the code, is a question for counsel and the licensor.

The root licence changed 2 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.

The newest was published on 2025-01-15. 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 1 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 26.10.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 33 records name self-hosted with nothing tying them to this repository (CVE-2025-0337, CVE-2025-11449, CVE-2025-11450, …).

1 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.
