ossrs/srs: technical due diligence, read from its repository

The median source file here is 172 lines. 158 files exceed 1,720 lines, the largest being 21,674. 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.

The code is pinned to Go 1.25 (end of life 2026-08-11). None of these receives security fixes any more; the first stopped on 2026-08-11. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

The newest pre-release, v7.0-a2, is not on the branch this survey read; the newest release on it is v6.0.48. The shipped product may differ from what this report describes. Survey the release branch too.

3 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.

2 of 78 locked dependencies match 2 published advisories in OSV. 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. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

Third-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

The newest was published on 2026-10-06. 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 6.0.48. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 8 records name srs with nothing tying them to this repository (CVE-2020-5766, CVE-2021-21517, CVE-2021-38544, …).

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.
