freshrss/freshrss: technical due diligence, read from its repository

The median source file here is 133 lines. 10 files exceed 1,330 lines, the largest being 5,587. 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.

18 files were marked deprecated over two years ago and still are, the oldest since Apr 2014. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

9 places read data with a deserialiser that executes what it reads (PHP `unserialize`). That is safe on data the system wrote itself and remote code execution on anything else. Ask where each one's input comes from.

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 2026-09-26. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. None of them affects the surveyed version.

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.

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.
