gofiber/fiber: technical due diligence, read from its repository
What Borehole read in gofiber/fiber's code and history at ae1ef46: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Security & Reliability Posture
adequate3 credential-shaped strings in the tree sit in tests, examples, documentation or local development settings
adequateStrings shaped like credentials appear only where fakes are usual: test fixtures, examples, documentation, placeholders and local stacks. They are almost always fakes. Ask someone to confirm that none of them works anywhere, because a real key in a development file is still a real key.
| 3 cited: JWT, where fakes are usual |
The build runs third-party code it does not pin
adequate14 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.
.github/workflows/after-release.yml:42 — action pinned by tag |
.github/workflows/auto-labeler.yml:17 — action pinned by tag |
2 outbound calls can wait forever
adequate2 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.
client/client.go:832 — outbound call without a timeout |
client/client.go:956 — outbound call without a timeout |
Relicensed: GPL-3.0 → MIT (2020-01-06) → Apache-2.0 (2020-01-13) → MIT (2020-01-16)
adequateThe root licence changed 3 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.
12 advisories against this project in the last 24 months, 5 high or critical
adequateThe newest was published on 2026-08-12. 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. The record is incomplete: NVD: 2 records name fiber with nothing tying them to this repository (CVE-2024-6355, CVE-2025-1081).
| 2026-08-12: GHSA-c5qf-v26h-rp5r (moderate), fixed in >= v2.52.15: idempotency middleware: default MemoryLock leaks one mutex per unique key (memory-exhaustion DoS) |
| 2026-07-02: GHSA-g5vh-55hw-rxm8 (moderate), fixed in 3.3.0: GoFiber Vulnerable to Username Enumeration via Timing Oracle in BasicAuth Default Authorizer |
| 2026-07-02: GHSA-gcfq-8gqf-4876 (moderate), fixed in 2.52.14: GoFiber Vulnerable to X-Real-IP Spoofing via Header.Add() in BalancerForward |
| 2026-07-02: GO-2026-5912 (moderate), fixed in 3.4.0: GoFiber never set HSTS header in helmet middleware due to incorrect protocol check in github.com/gofiber/fiber |
| 2026-04-25: GHSA-35hp-hqmv-8qg8 (moderate), fixed in 3.2.0: Fiber's cache middleware default key generator ignores query string, causing response mix-up across distinct query parameters |
Observability & Operations
adequateNo telemetry or error reporting is wired in anywhere
adequateNone of 461 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.
| searched 461 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched |
No structured logging library is in use
adequateNothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.
| searched 461 files for 10 structured logging libraries; 0 matched |
No error reporter is wired in
adequateNothing 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.
| no error reporter initialised |
