This allows users to decide if they want to treat syntax warnings as blocking issues or ignore them during scans. - Refactoring get_python_file_asts: - Improved the logic that captures and reports errors during AST generation. - Standardized error messages to make them more descriptive when a file fails to parse. - Integrated the new enable_syntax_warnings logic within the core file-walking loop. - Created a new test suite test_get_asts.py to verify: - Default behavior (warnings ignored). - Behavior when warnings are enabled (treated as errors/exceptions). - Handling of valid, invalid, and encoding-error files. --------- Co-authored-by: Tommaso Bona --- src/pyspector/cli.py | 97 ++++++++++++++++++++++++++----------- tests/unit/test_get_asts.py | 74 ++++++++++++++++++++++++++++ 2 files changed, 144 insertions(+), 27 deletions(-) create mode 100644 tests/unit/test_get_asts.py diff --git a/src/pyspector/cli.py b/src/pyspector/cli.py index 8943f8a9..9c4f5677 100644 --- a/src/pyspector/cli.py +++ b/src/pyspector/cli.py @@ -125,40 +125,75 @@ def should_skip_file(file_path: Path) -> bool: return False -def get_python_file_asts(path: Path) -> List[Dict[str, Any]]: +def get_python_file_asts(path: Path, enable_syntax_warnings: bool = False) -> List[Dict[str, Any]]: """Recursively finds Python files and returns their content and AST.""" results = [] -

Manual verification showed that **~720 were false positives**: - **453** from `PY515`/`SHELL645`/`SHELL670` — flagging every `re.compile()` call as "code compilation" - **101** from `PY102` — the taint engine firing on generic callable invocations - **78** from `PY511`/`JSON612` — `json.loads()` flagged as dangerous deserialization - **dozens more** from `AUTH711`, `CSRF747`, `SESS744`, `PATH813`, etc. — firing on test fixtures and well-known safe patterns Without filtering, scanning also revealed ~9,000 additional Low-severity findings from rules that flag every Python built-in (`isinstance`, `super`, `len`, f-strings, `getattr`, etc.). ### Solution #### 1. `[defaults]` section in rules TOML ```toml [defaults] exclude_file_patterns = ["*tests*", "*fixtures*", "*testdata*", "*conftest*"] disabled_rule_ids = ["ISINSTANCE855", "LEN1101", "SUPER1128", ...] ``` - `exclude_file_patterns` — glob list applied to **all rules**; eliminates the need to repeat `exclude_file_pattern` on every individual rule - `disabled_rule_ids` — completely disables noisy rules without deleting their definitions (easy to re-enable per project) #### 2. Per-rule `exclude_pattern` Regex matched against the flagged line; suppresses the finding if it matches. Fixes rules that are correct in general but have well-known safe variants: ```toml [[rule]] id = "PY107" ast_match = "Call(func.value.id=yaml, func.attr=load)" # Safe when Loader=SafeLoader is explicitly passed exclude_pattern = "Loader\\s*=\\s*(yaml\\.)?(Safe|Base)Loader" ``` ### Results on Django 6.1-alpha | | Before | After | |---|---|---| | Total findings (all severities) | 864 (-s HIGH) | **383** | | `re.compile()` false positives | 453 | **0** | | `yaml.load(SafeLoader)` false positives | 2 | **0** | | Test fixture credential false positives | 9 | **0** | | Session fixation false positives | 1 | **0** | | Python built-in noise rules | ~9,000 (hidden by -s HIGH) | **0** | | `pickle.loads()` true positives | 57 → 8 (test files excluded) | **✓ present** | | `exec()` true positives | 3 | **✓ 3** | ### Files changed - `src/pyspector/_rust_core/src/rules.rs` — `Defaults` struct, `Rule::is_file_excluded()`, `exclude_pattern` field - `src/pyspector/_rust_core/src/analysis/mod.rs` — apply `disabled_rule_ids` before scan - `src/pyspector/_rust_core/src/analysis/ast_analysis.rs` — use `is_file_excluded()` and `exclude_pattern` - `src/pyspector/_rust_core/src/analysis/config_analysis.rs` — same - `src/pyspector/rules/built-in-rules.toml` — `[defaults]` section + per-rule fixes - `tests/unit/test_false_positive_reductions.py` — 26 tests (each fix has a suppression test + true-positive retention test) ## Test plan - [x] `python -m pytest tests/unit/test_false_positive_reductions.py` — 26 tests pass - [x] Scan a Django project: `pyspector scan /path/to/django` — confirm `re.compile()`, `yaml.load(SafeLoader)`, and test-fixture findings are gone - [x] Confirm `pickle.loads()` and `exec()` findings still present in production code Co-authored-by: satoridev01 --- .../_rust_core/src/analysis/ast_analysis.rs | 23 +- .../src/analysis/config_analysis.rs | 11 + src/pyspector/_rust_core/src/analysis/mod.rs | 13 +- src/pyspector/_rust_core/src/rules.rs | 42 ++ src/pyspector/rules/built-in-rules.toml | 72 +++- tests/unit/test_false_positive_reductions.py | 404 ++++++++++++++++++ 6 files changed, 553 insertions(+), 12 deletions(-) create mode 100644 tests/unit/test_false_positive_reductions.py diff --git a/src/pyspector/_rust_core/src/analysis/ast_analysis.rs b/src/pyspector/_rust_core/src/analysis/ast_analysis.rs index 8b7c17ae..715dd5c9 100644 --- a/src/pyspector/_rust_core/src/analysis/ast_analysis.rs +++ b/src/pyspector/_rust_core/src/analysis/ast_analysis.rs @@ -1,6 +1,6 @@ use crate::ast_parser::AstNode;

excludes regex string accessor | Eliminated satori-cli (Python 3.12 safe filter) + pandas ×4 FPs | ### Taint Engine Changes (`taint_analysis.rs`) | Area | What changed | |---|---| | Sources | The engine now recognizes more entry points as attacker-controlled: HTTP handler parameters detected via route decorators, HTTP client responses, and file contents loaded via deserialization functions. File contents are always treated as potentially attacker-controlled even when the file path itself was chosen by the operator — this is what enables supply-chain detection. | | Origin model | Not all external input is equally dangerous. Data coming from CLI arguments, environment variables, or deployment configuration is operator-supplied and treated as trusted. Data coming from HTTP requests or deserialized file contents is attacker-controlled. Sinks only fire on the latter, which eliminates an entire class of false positives on CLI tools without touching any individual rule. | | Propagation | Taint now follows data across function call boundaries, through class attributes, and through control flow constructs like loops, context managers, and exception handlers. Previously, taint was lost as soon as data crossed a function boundary or was stored in an object. | | Sanitizers | The engine recognizes functions that clean data — database query escaping clears SQL taint, HTML escaping clears HTML taint. Partially sanitized data (e.g., HTML-escaped but not shell-escaped) does not get promoted to fully clean. | | Performance | Analysis skips functions that have no tainted data flowing through them, runs the convergence loop and final pass in parallel, and caches control flow graphs between iterations. Combined with the call graph improvements, this reduced scan time on large repos by 2–5×. | ### New Infrastructure | Feature | Description | |---|---| | `file_content_exclude` field on Rule | Per-file content regex checked ONCE before any analysis — prevents rule from firing on files that import a specific library | | Comma-separated `exclude_file_pattern` | Was treated as a single literal pattern; now split on comma — fixed all multi-pattern exclusions that were silently not working | | `vulnerable_keyword` on TaintSinkRule | Sink only fires for a specific named kwarg (e.g., `create(password=tainted)`) — prevents positional arg FPs | | CLI vs HTTP taint origin | `@app.command()` / Click / Typer parameters → `TaintOrigin::OperatorConfig`; HTTP request parameters → `TaintOrigin::HttpRequest`. Operator-supplied paths are not injection vectors.

Default output keeps the banner (name, version, credits, joke), findings, warnings and errors. `--debug` re-enables the previous verbose output, including `println!` lines from the Rust core (silenced by redirecting fd 1 to `/dev/null` around `run_scan` / `scan_supply_chain`). - **Dynamic version in the banner**: the displayed version is now read via `importlib.metadata.version("pyspector")` instead of being hardcoded in `cli.py`, so it stays in sync with `setup.cfg` on every bump. - **Honor `exclude` in the Python pre-pass**: `get_python_file_asts` now filters `path.glob("**/*.py")` against the config's `exclude` list. Previously only the Rust core respected it, so the walker still entered `.venv/` / `node_modules/` and emitted a `Info: Skipped` per file inside them. New `_is_path_excluded` helper matches patterns against relative path, absolute path and individual path components. - **Default excludes**: added `node_modules`, `bower_components`, `vendor` to `DEFAULT_CONFIG.exclude` in `config.py` alongside the existing `.venv` / `__pycache__` / `build` / `dist` / `*.egg-info` / `venv` entries. ### Before / After Scanning a project containing a `.venv/`: **Before** (truncated — actually printed ~150 `Info: Skipped` lines from setuptools/pbr tests inside .venv): ``` Info: Skipped .venv/lib/python3.13/site-packages/pbr/tests/test_version.py (test file or fixture) Info: Skipped .venv/lib/python3.13/site-packages/pbr/tests/test_packaging.py (test file or fixture) ...

Eliminates placeholder FPs like `hf_token`, `hf_X`, `hf_xxx_your_token`, `hf_....`. Doctest lines (`>>>` / `...`) excluded. - **`G104`** (JWT secret): pattern now requires `â‰Ĩ16` non-quote chars in the value (previously `.+` matched literal field-name values like `"kb_jwt"`). `exclude_pattern` added: `your_`, `change-(me|in-production)`, `default-secret`, `do-not-share`, `demo-`, `never-(hardcode|use)`. - **`G101`** (broad password/secret): `exclude_pattern` extended to suppress: - common placeholder values: `your_`, `insert_`, `example_`, `placeholder`, `change-me`, `replace-me`, `todo`, `fake`, `dummy`, `sample`, `demo`, `server_api_key`, `api_key_secret`, `my_password`, `root_password` - values ending in `_here` / containing `*_HERE` - all-uppercase placeholder-name strings like `"YOUR_OPENAI_API_KEY"` - lines starting with `print(`, `click.echo(`, `sys.stderr.` (instructional output) - doctest lines (`>>>` / `...`) - **`G101B`** (uppercase const secret): same placeholder / instructional-line / doctest exclusions. - **`G102`** (private key block): added `exclude_file_pattern = "*.md,*.rst,*.html,*.txt,*.adoc,*.tex,*.ipynb"`. Documentation / walkthrough / knowledge-base content showing `-----BEGIN â€Ļ PRIVATE KEY-----` as an example was a 100% FP source in our corpus. - **`G103`** (blank password): `exclude_pattern` adds `^\s*[A-Z][A-Z0-9_]+\s*=` (Django/Flask uppercase config defaults like `EMAIL_HOST_PASSWORD = ""` are intentionally overrideable from env). `exclude_file_pattern` adds `*settings*.py,*config*.py`. - **`G117`**, **`G113`**: explicit `-your-`, `-here\b`, `-replace-` substring excludes catch patterns like `xoxb-your-slack-bot-token` and `sk-svcacct-your-embedding-key-here`. `exclude_file_pattern` adds `*.env.example,*.env.template,*.env.sample,*.env.dist,env.example`. ### G121 / G121L — production vs dev-default split `G121` (Critical / High) now excludes connection strings whose host is one of the well-known local/docker-compose names (`localhost`, `127.0.0.1`, `0.0.0.0`, `::1`, `host.docker.internal`, `db`, `database`, `postgres(ql)`, `mysql`, `mariadb`, `mongo(db)`, `redis`, `rabbitmq`, `broker`, `kafka`, `memcached`, `amqp`). Host tokens are matched only when followed by a URL-component terminator (`:`, `/`, `?`, `#`, quote, whitespace), so substrings like `db.prod.example.com` still hit G121 — only standalone host tokens like `@db:5432` get downgraded. **`G121L`** (new, Low / Low) covers the dev-default class: same connection-string shape, but only when the host is one of those local/container names. This converts the dominant remaining G121 FP class — `postgresql://guaardvark:guaardvark@localhost:5432/guaardvark`-style local-dev defaults — into a separate, low-priority signal that an analyst can choose to ignore or batch-review, without dropping the finding entirely (it is still a literal hardcoded credential). `[defaults].exclude_pattern_placeholder` now declares the placeholder/dummy-secret regex (`(?i)EXAMPLE|FAKE|PLACEHOLDER|SAMPLE|x{10,}|0{10,}|1{10,}|abcdefghij|1234567890abcdef|AbCdEfGhIjKlMnOp|f3a8b2c1`) in one place. Each rule's `exclude_pattern` references it via the sentinel `__SHARED_PLACEHOLDERS__`, which `get_default_rules()` (in `pyspector/config.py`) string-substitutes before handing the TOML text to the Rust core. Adding a new placeholder shape is now a one-line edit rather than touching 15 rule blocks. The Rust core needs no changes — substitution happens in the existing Python rule-loading path. Existing rule TOMLs without the sentinel continue to work unchanged. ### G122 unscoping `G122` previously had `file_pattern = "*.py"`. JWTs leak into `.yaml`, `.json`, `.sh`, `.tf`, and CI configs at least as often as into Python files. Removing the restriction adds new TP coverage without measurable FP impact (2 new hits in the validation corpus, both edge cases in `.drawio` and `.json` files containing image-URL JWTs). ### Shared FP fixes triggered by the validation corpus - **`G121`** / **`G123`** now suppress f-string and shell interpolation in the credential portion: `{var}`, `{self.x}`, `${VAR}`, `$(VAR)`, `$VAR`, ``, `{{ var }}` (Jinja/Helm). - **`G121`** ignores `re.match()` / `re.compile()` / `re.search()` patterns that happen to describe a connection-string shape. - **`G123`** pattern now forbids `/` in the password segment, eliminating the dominant JS-stack-trace FP class (`http://localhost:5173/node_modules/.vite/deps/@react.js?â€Ļ:759:3) @ http://â€Ļ`). `*.log` added to `exclude_file_pattern`. - **`G121`** / **`G123`** add `*.env.example,*.env.template,*.tpl,*.j2,*.jinja,*.template,*cookiecutter*` to `exclude_file_pattern`. - **`G114`** placeholder filter now suppresses Slack webhook URLs with `T00000000/B00000000/XXXXâ€Ļ` template values. - **`G110`** suppresses `AKIAIOSFOLQUICKSTART` (well-known lakefs quickstart documented credential). ## Validation Comparison with TruffleHog (v3.95.3) on 763 repos that originally flagged any "Hardcoded" finding.** Both tools scanned the same shallow clones; PySpector with the new rules, TruffleHog with `--no-verification` for fair format-vs-format comparison. | Tool | Findings | Heuristic-TP | Heuristic-FP | Precision | |---|---:|---:|---:|---:| | **PySpector v2 (this PR)** | 1,135 | 884 | 251 | **78%** | | TruffleHog 3.95.3 (no-verify) | 5,814 | 462 | 5,352 | **8%** | Comparison with PySpector vs Modified PySpector | Metric | Original | This PR | Change | |-------------------------|---------:|---------:|-------------:| | Total findings | 2,295 | 1,135 | **−51%** | | Heuristic-TP | 1,242 | 884 | −29% | | Heuristic-FP | 1,053 | 251 | **−76%** | | Precision | 54.1% | 77.9% | **+23.8pp** | | TP : FP ratio | 1.18 | 3.52 | **~3× better** | Per-rule breakdown (500 OK-cloned repo subset) | Rule | Original | This PR | Notes | |-------|---------:|--------:|------------------------------------------------------------------------------| | G101 | 1,743 | 702 | Tightened exclude — kills ~60% of placeholder / instructional-output FPs | | G101B | 359 | 0 | Largely subsumed by the new format-specific rules; placeholders also filtered | | G102 | 138 | 100 | `.md`/`.rst` doc-extension excludes drop ~30 walkthrough FPs | | G103 | 48 | 34 | `UPPER_CASE = ""` config-default and `*settings*.py` excludes | | G104 | 2 | 2 | Same hits | | AI404 | 5 | 1 | Tightened to require â‰Ĩ16 alnum chars after `hf_` | | G110 | — | 1 | NEW — AWS access key (`AKIAâ€Ļ`) | | G115 | — | 2 | NEW — Stripe live/test keys | | G116 | — | 187 | NEW — Google API key (`AIzaâ€Ļ`) | | G117 | — | 22 | NEW — OpenAI `sk-â€Ļ` / `sk-proj-â€Ļ` | | G121 | — | 49 | NEW — DB connection string with embedded credentials | | G122 | — | 26 | NEW — three-part JWT in code (now non-Python files too) | | G123 | — | 8 | NEW — basic-auth URL | | G127 | — | 1 | NEW — Telegram bot token | | G110–G127 total | 0 | 296 | NEW provider coverage absent from the original ruleset | | **TOTAL** | 2,295 | 1,135 | | --- src/pyspector/config.py | 31 +- src/pyspector/rules/built-in-rules-ai.toml | 7 +- src/pyspector/rules/built-in-rules.toml | 362 ++++++++++++++++++++- 3 files changed, 386 insertions(+), 14 deletions(-) diff --git a/src/pyspector/config.py b/src/pyspector/config.py index 785e1819..bf836f37 100644 --- a/src/pyspector/config.py +++ b/src/pyspector/config.py @@ -1,3 +1,4 @@ +import re from pathlib import Path import toml # type: ignore import click # type: ignore @@ -8,6 +9,16 @@ # Fallback for older Python versions import importlib_resources as pkg_resources # type: ignore +# Sentinel placed inside any rule's `exclude_pattern` to inherit the shared +# placeholder regex declared at [defaults].exclude_pattern_placeholder.

When two rules report findings at the same (file, line) and share the same CWE (e.g. DESER_TORCH001 + AI202 both flagging one torch.load line under CWE-502), the engine collapses them: the finding whose rule declares the higher severity wins, with rule_id lex order as stable tiebreaker on equal severity. CWE itself does not set severity — each rule's severity comes from its own TOML field. Distinct CWEs at the same line stay distinct, so `os.system(eval(user_input))` correctly reports both CWE-78 and CWE-94. Rust core - rules.rs / issues.rs: new optional `cwe: Option`, carried from Rule → Issue and exposed to Python via pyo3 - analysis/{config,ast,taint}_analysis.rs: pass it through Issue::new - analysis/mod.rs: 2-stage dedup stage 1 = existing fingerprint dedup (same rule, exact match) stage 2 = CWE-aware merge by (file, line, cwe), highest severity wins. Rules without a CWE skip stage 2. cli.py - file_path passed to Rust is now `py_file.resolve()` (absolute, canonical) so AST-rule and pattern-rule findings agree on the same path string and stage-2 dedup actually triggers. reporting.py - JSON output gains a top-level `cwe` field on each issue - SARIF output emits `external/cwe/cwe-N` in each rule's `properties.tags` — standard SARIF taxon, parses cleanly in GitHub Code Scanning and DefectDojo setup.py - RustExtension declares `debug=False` so `pip install -e .` produces release-mode binaries; previously editable installs ran ~3× slower. Rules — all 179 [[rule]] blocks now declare a CWE (built-in-rules.toml + built-in-rules-ai.toml). Mapping summary: CWE-78 command injection PROC819, SHELL602/689, PY102/103/106, AI503, ...

Subject: [PATCH 36/36] feat: add incremental AST cache to eliminate redundant AstEncoder work Three-level (L1 in-memory mtime / L2 disk content-hash / L3 chunk-aware) incremental AST cache that skips the pure-Python json.dumps(AstEncoder) bottleneck across runs and on partial file changes. - src/pyspector/ast_cache.py: cache implementation (JSON+base64 persistence, no pickle/code-exec on load) - src/pyspector/_ast_encode.py: shared AST->JSON encoder (single source of truth, eliminates encoder drift between cli.py and the cache) - src/pyspector/cli.py: wire the cache into get_python_file_asts
