From b22bf574a7d51233ed70acc6551724a60584edf7 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 3 Jun 2026 07:06:21 +0000 Subject: [PATCH 01/23] Fix scoring/runner correctness bugs and reconcile inflated claims Code correctness: - scoring: make overall risk score monotonic (cumulative noisy-OR) so discovering more findings never lowers the headline score - runner: count multi-agent verdicts (INFECTION_PROPAGATED/COLLUSION/ WATCHDOG_BYPASS) as vulnerabilities; fixes KeyError in the ASI summary and silent mis-counting as inconclusive - evaluators/base: honour cascade thresholds of 0 (was treated as no-limit) - evaluators/rce: drop redundant 'uid=' pattern that double-counted a single benign 'uid=0' into a false-positive VULNERABLE - ai_vss: unify REFUSAL_ECHO discount with scoring (35%, was 40%) - cli/run: actually emit HTML when --format html is requested Claims reconciled with reality: - README: test badge -> real collected count, python badge -> 3.10+, attribute the 84.30% figure to Agent Security Bench, replace fabricated '1002 tests' table with verifiable measured numbers - paper.md: scenario count 50 -> 130+ to match the shipped registry - CHANGELOG: add 2.0.0 entry (file had stopped at 0.4.1) - cve-scenarios + CVE01-001: correct CVE-2025-68664 -> CVE-2025-64439 (LangGraph JsonPlusSerializer RCE); fix invalid CLI example - npm: align package name to the published 'asi-scan' in README/workflow CI: - scenario-validation job: use find instead of a '**' glob (globstar is off by default, so it was validating zero scenarios) Updated property-based scoring tests to assert the new monotonic invariant. --- .github/workflows/ci.yml | 11 ++++- .github/workflows/publish-npm.yml | 2 +- CHANGELOG.md | 42 +++++++++++++++++ README.md | 43 +++++++++--------- docs/cve-scenarios.md | 11 ++--- packages/aastf-js/README.md | 12 ++--- paper.md | 11 +++-- src/aastf/ai_vss.py | 8 +++- src/aastf/cli/commands/run.py | 6 +++ src/aastf/runner.py | 45 ++++++++++++------- .../scenarios/builtin/cve01/CVE01-001.yaml | 10 +++-- src/aastf/scenarios/evaluators/base.py | 8 +++- src/aastf/scenarios/evaluators/rce.py | 3 +- src/aastf/scoring.py | 32 ++++++++----- tests/unit/test_scoring_hypothesis.py | 35 ++++++++++++++- 15 files changed, 202 insertions(+), 77 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 0794466..11d5549 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -63,11 +63,18 @@ jobs: python-version: "3.12" - run: pip install -e ".[dev]" - run: | - for f in src/aastf/scenarios/builtin/**/*.yaml;

Previously the MCP verdicts (TOOL/SCHEMA/PREFERENCE) and multi-agent verdicts (INFECTION_PROPAGATED/COLLUSION/WATCHDOG_BYPASS) were counted as vulnerable by the runner but ignored by the risk score, EU AI Act readiness, the SARIF/HTML/console reporters and --fail-on gating — so a scan with 3 CRITICAL COLLUSION findings reported 'Vulnerable: 3' yet risk 0.0, 'compliant', an empty SARIF, and exited 0 under --fail-on critical. - Wire scoring.compute_risk_score, eu_ai_act_readiness, sarif/html/console reporters, run.get_blocking_findings, and the drift/scheduler/scoring_dual/ evidence_reporter verdict sets to the canonical set. - Add tests/unit/test_verdict_consistency.py locking in end-to-end handling. Adapter false negative: - anyio.move_on_after returns normally on timeout (no exception), so a timed-out agent was scored SAFE instead of recorded as an error. Capture the cancel scope and set_error when it fires, across all 7 execution adapters. - runner._evaluate now short-circuits an errored trace to ERROR rather than scoring an empty/partial trace as SAFE. CLI: - Register 'serve' as a direct command so 'aastf serve --port' works instead of requiring 'aastf serve serve'.

Scenario authors wrote several substrings under the same tool key intending 'fail if ANY match', but YAML collapses duplicate mapping keys to the last value — silently dropping most patterns in 30 scenarios. ASI05-005 lost all Linux path-traversal detection ('../', '/etc/passwd'), leaving only a Windows pattern and no fallback, so it could not detect the attack it describes. - Schema is now dict[str, list[str]] with a validator that also accepts a single string (normalised to a one-element list) for backward compatibility. - _check_tool_input_contains matches if ANY listed substring is present. - Rewrote all 30 affected scenarios from duplicate keys to explicit list form, restoring every dropped pattern (verified: ASI05-005 again carries '../' and '/etc/passwd'; CVE01-004 carries all 7 code-exec patterns). - Loader now rejects duplicate mapping keys (_UniqueKeyLoader) so this silent collapse can never recur in builtin scenarios or third-party packs. - Hardened render_payload to a SandboxedEnvironment, blocking template-injection (SSTI) via attacker-controlled pack payloads; strengthened the supply-chain loader-safety test to verify it behaviourally. Tests: added schema list/normalisation coverage and an any-of evaluator regression; updated the loader-safety test. 2834 collected, suite green. --- README.md | 4 +- src/aastf/models/scenario.py | 19 +++++++- .../scenarios/builtin/asi02/ASI02-004.yaml | 7 +-- .../scenarios/builtin/asi02/ASI02-005.yaml | 5 ++- .../scenarios/builtin/asi03/ASI03-004.yaml | 5 ++- .../scenarios/builtin/asi03/ASI03-005.yaml | 7 +-- .../scenarios/builtin/asi03/ASI03-007.yaml | 5 ++- .../scenarios/builtin/asi04/ASI04-004.yaml | 5 ++- .../scenarios/builtin/asi04/ASI04-005.yaml | 7 +-- .../scenarios/builtin/asi05/ASI05-003.yaml | 13 +++--- .../scenarios/builtin/asi05/ASI05-004.yaml | 9 ++-- .../scenarios/builtin/asi05/ASI05-005.yaml | 7 +-- .../scenarios/builtin/asi05/ASI05-006.yaml | 7 +-- .../scenarios/builtin/asi05/ASI05-007.yaml | 5 ++- .../scenarios/builtin/asi05/ASI05-009.yaml | 5 ++- .../scenarios/builtin/asi06/ASI06-001.yaml | 5 ++- .../scenarios/builtin/asi06/ASI06-004.yaml | 5 ++- .../scenarios/builtin/asi06/ASI06-007.yaml | 9 ++-- .../scenarios/builtin/asi06/ASI06-016.yaml | 5 ++- .../scenarios/builtin/asi07/ASI07-004.yaml | 5 ++- .../scenarios/builtin/asi07/ASI07-005.yaml | 5 ++- .../scenarios/builtin/asi09/ASI09-003.yaml | 7 +-- .../scenarios/builtin/asi10/ASI10-002.yaml | 7 +-- .../scenarios/builtin/asi10/ASI10-005.yaml | 5 ++- .../scenarios/builtin/cve01/CVE01-001.yaml | 9 ++-- .../scenarios/builtin/cve01/CVE01-002.yaml | 9 ++-- .../scenarios/builtin/cve01/CVE01-003.yaml | 13 +++--- .../scenarios/builtin/cve01/CVE01-004.yaml | 15 ++++--- .../scenarios/builtin/cve01/CVE01-005.yaml | 9 ++-- .../scenarios/builtin/cve01/CVE01-006.yaml | 7 +-- .../scenarios/builtin/cve01/CVE01-007.yaml | 13 +++--- .../scenarios/builtin/cve01/CVE01-008.yaml | 17 +++---- src/aastf/scenarios/evaluators/base.py | 12 ++--- src/aastf/scenarios/loader.py | 44 +++++++++++++++++-- tests/adversarial/test_g_supply_chain.py | 32 ++++++++++---- tests/unit/test_evaluators.py | 32 ++++++++++++++ tests/unit/test_models_scenario.py | 12 ++++- 37 files changed, 264 insertions(+), 123 deletions(-) diff --git a/README.md b/README.md index 446b9b2..52522d9 100644 --- a/README.md +++ b/README.md @@ -8,7 +8,7 @@ [![CI](https://github.com/anonymousAAK/aastf/actions/workflows/ci.yml/badge.svg)](https://github.com/anonymousAAK/aastf/actions) [![PyPI](https://img.shields.io/pypi/v/aastf?cacheBust=1)](https://pypi.org/project/aastf/) [![Downloads](https://img.shields.io/pypi/dm/aastf?cacheBust=1)](https://pypi.org/project/aastf/) -[![Tests](https://img.shields.io/badge/tests-2831%20passed-brightgreen)](TESTING.md) +[![Tests](https://img.shields.io/badge/tests-2834%20passed-brightgreen)](TESTING.md) [![Python](https://img.shields.io/badge/python-3.10%2B-blue)](https://www.python.org) [![License: MIT](https://img.shields.io/badge/License-MIT-green.svg)](LICENSE) [![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.20296480.svg)](https://doi.org/10.5281/zenodo.20296480) @@ -294,7 +294,7 @@ Layer 1: Harness OTEL .

Wired into alerting and scheduler. - otel PrometheusMetricsServer now binds 127.0.0.1 by default (was 0.0.0.0, which AASTF's own static analyzer flags) with an opt-in host parameter. - Add PEP 561 py.typed marker + 'Typing :: Typed' classifier so downstream type-checkers honour AASTF's annotations. - Remove the loguru runtime dependency (unused; the codebase logs via stdlib). - compliance pack: pass EU AI Act article ids as strings (the builder keys weights/dirs by string) instead of ints, fixing a real type/lookup mismatch. - Bump Development Status classifier 3-Alpha -> 4-Beta to match the 2.0.0 release. Tests: add URL-validation coverage. 2843 collected, suite green. --- README.md | 4 +-- pyproject.toml | 4 +-- src/aastf/alerting.py | 10 ++++++- src/aastf/cli/commands/compliance.py | 12 ++++---- src/aastf/netsec.py | 37 +++++++++++++++++++++++ src/aastf/otel.py | 9 ++++-- src/aastf/py.typed | 0 src/aastf/scheduler.py | 16 ++++++++++ tests/unit/test_netsec.py | 45 ++++++++++++++++++++++++++++ 9 files changed, 125 insertions(+), 12 deletions(-) create mode 100644 src/aastf/netsec.py create mode 100644 src/aastf/py.typed create mode 100644 tests/unit/test_netsec.py diff --git a/README.md b/README.md index 52522d9..20f3300 100644 --- a/README.md +++ b/README.md @@ -8,7 +8,7 @@ [![CI](https://github.com/anonymousAAK/aastf/actions/workflows/ci.yml/badge.svg)](https://github.com/anonymousAAK/aastf/actions) [![PyPI](https://img.shields.io/pypi/v/aastf?cacheBust=1)](https://pypi.org/project/aastf/) [![Downloads](https://img.shields.io/pypi/dm/aastf?cacheBust=1)](https://pypi.org/project/aastf/) -[![Tests](https://img.shields.io/badge/tests-2834%20passed-brightgreen)](TESTING.md) +[![Tests](https://img.shields.io/badge/tests-2843%20passed-brightgreen)](TESTING.md) [![Python](https://img.shields.io/badge/python-3.10%2B-blue)](https://www.python.org) [![License: MIT](https://img.shields.io/badge/License-MIT-green.svg)](LICENSE) [![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.20296480.svg)](https://doi.org/10.5281/zenodo.20296480) @@ -294,7 +294,7 @@ Layer 1: Harness OTEL .

This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error. If no error handler is provided,\n * the error will be thrown asynchronously as unhandled.\n * @param complete A handler for a terminal event resulting from successful completion.\n * @return A subscription reference to the registered handlers.\n */\n subscribe(\n observerOrNext?: Partial> | ((value: T) => void) | null,\n error?: ((error: any) => void) | null,\n complete?: (() => void) | null\n ): Subscription {\n const subscriber = isSubscriber(observerOrNext) ? observerOrNext : new SafeSubscriber(observerOrNext, error, complete);\n\n errorContext(() => {\n const { operator, source } = this;\n subscriber.add(\n operator\n ? // We're dealing with a subscription in the\n // operator chain to one of our lifted operators.\n operator.call(subscriber, source)\n : source\n ? // If `source` has a value, but `operator` does not, something that\n // had intimate knowledge of our API, like our `Subject`, must have\n // set it.
