high Security checks quality Quality conf 1.00 ✓ Repobility [MINED036] Python Os System Call: os.system() invokes shell with no escaping.
Review and fix per the pattern semantics. See CWE-78 / for context.
embassy-time-driver/gen_tick.py:84
high Security checks security path traversal conf 0.80 [SEC013] Path Traversal — User Input in File Path: User-controlled input used in file path without sanitization. Allows reading arbitrary files.
Use os.path.realpath() and verify the path starts with your expected base directory. Use secure_filename() for uploads.
examples/stm32wba6/convert_wav.py:15
high Security checks security Crypto conf 1.00 [SEC106] Block cipher in ECB mode (AES/DES/Blowfish): ECB mode leaks block-level structure — identical plaintext blocks encrypt to identical ciphertext (the famous Tux image). Bare `Cipher.getInstance("AES")` defaults to ECB on most JVMs.
Use GCM (recommended): `Cipher.getInstance("AES/GCM/NoPadding")`. Or CBC with HMAC. Always pass an explicit IV; never reuse it for GCM.

low Security checks cicd CI/CD security conf 0.90 ✓ Repobility 4 occurrences GitHub Action is tag-pinned rather than SHA-pinned
Action `actions/github-script` pinned to mutable ref `@v8` uses a mutable tag or branch. Pin external actions to a reviewed full commit SHA when the workflow is security-sensitive.

low Security checks quality Error handling conf 0.55 ✓ Repobility Broad exception handler needs review
This handler catches Exception/BaseException. It is actionable when it swallows errors without logging, re-raising, or returning a structured error. Handlers that intentionally convert exceptions into typed error results should not be treated as high risk.

high Security checks software dependencies conf 0.90 GitHub Action `actions/github-script@v8` is 1 major version(s) behind (latest v9.0.0)
`uses: actions/github-script@v8` is 1 major version(s) behind the latest published release v9.0.0. Old action majors run on deprecated runner images / Node versions and miss upstream fixes. This is the exact 'outdated GitHub Action' class Dependabot raises — and which Repobility had no coverage for.

`def feature(... = []/{}/set())` — Python's default value is constructed ONCE at function definition time and shared across all calls. Mutating it in one call mutates it for every future call too.

Duplicate implementation blocks are maintenance debt. Keep them visible, but they are not a high-severity defect unless the duplicated logic is security-sensitive or drifting.
