Framework changelogs and security advisories (MCP spec, OpenClaw, etc.) + +ATLAS scope note: ATLAS covers the entire ML/AI attack surface — model +extraction, data poisoning, evasion, membership inference, and more. Most +of that is OUT OF SCOPE for AVE, which enumerates AGENT COMPONENT behaviors +(skills, MCP servers, tool descriptions), not model training or inference +attacks. Expect many ATLAS techniques to be correctly out of scope. That is +not a gap in AVE — it is the boundary of the standard. + +Avoid: vendor marketing blogs without a primary source, forum speculation, +LinkedIn hot takes.

Do not write records yet. + +### Phase 2: Benchmark against existing AVE records + +For each candidate, load every record in `records/` and compare on +BEHAVIOR, not wording. The question is never "do the strings match" — +it is "does an existing AVE already describe this behavior?" + +Compare against each existing record's: +- `attack_class` +- `behavioral_fingerprint` +- `description` +- `detection_layer` + +Decide one of four outcomes: + +**ALREADY COVERED** — an existing record's behavioral_fingerprint already +describes this. Even if the research uses a different name, if the behavior +is the same, it is covered. Log it, do nothing else. +Example: a paper's "TV1 Description Injection" maps to an existing +tool_description_injection record → ALREADY COVERED. + +**VARIANT OF EXISTING** — same parent behavior, meaningfully different +mechanism or surface, but not a distinct class. Do NOT create a new record. +Instead, note it as a sub-case in the parent record's description or +indicators_of_compromise. A variant never gets its own ave_id. +Example: "tool poisoning via unicode tag smuggling" is a variant of +tool_description_injection, not a new class. + +**OUT OF SCOPE** — a real, often ATLAS-catalogued attack that AVE +deliberately does not cover because it targets the model or training +pipeline, not an agent component. Log it as out of scope with the reason. +This is not a gap — it is the boundary of the standard. +Example: ATLAS data poisoning of training data, model extraction, +membership inference → OUT OF SCOPE (AVE covers agent components, not +model training or inference). + +**NEW CLASS** — no existing record describes this behavior, it is in scope +(an agent-component behavior), and it is not a thin variant. It operates on +a different surface, exploits a different trust assumption, or chains +differently. This earns a new record. +Example: "parasitic toolchain attack — multi-tool collaboration without a +single malicious server" is behaviorally distinct from single-server tool +poisoning → NEW CLASS. + +The bar for NEW CLASS is the deletion test applied to taxonomy: +"If we folded this into an existing record, would we lose a real +detection distinction, or just add a synonym?" Lose a distinction → NEW. +Add a synonym → VARIANT or ALREADY COVERED. + +### Phase 3: Report before implementing + +Produce a benchmark report.

(attack class, behavioral description) -- **Where** does it appear? (component type, affected registries, platforms) -- **How dangerous** is it?

Governance - -AVE v0.2.0 is maintained by [Bawbel](https://bawbel.io). - -### Current state - -Bawbel owns the AVE numbering system, the record schema, and the PiranhaDB -API. The specification is open source (Apache 2.0). Anyone can read it, -implement it, submit records, and propose changes via GitHub pull request. -Bawbel makes final decisions on schema changes and record acceptance today. - -### Guiding principle - -The long-term goal is for AVE to be governed by a neutral body where no -single organization holds a majority. What that body looks like, whether -an existing foundation such as OWASP, the Linux Foundation, or OpenSSF, -or something new, will be decided based on what the community and ecosystem -actually support. We are not planning that in advance. - -Bawbel's commitment: when AVE reaches the adoption level where neutral -governance makes sense, we will transfer ownership. We will not use -governance control to extract commercial advantage from the standard. - -### How to participate now - -- Submit AVE records via pull request (see [Section 9](#9-submitting-a-record)) -- Propose schema changes by opening a GitHub issue -- Implement AVE in your own tools (Apache 2.0, no permission needed) -- If your organization is interested in co-governing AVE as it matures, - email bawbel.io@gmail.com subject: `AVE Governance: [organization name]` - - ---- - -## 4.

Problem → standard → why it wins → the prize
+
+ +

The gap AVE fills

+

Conventional vulnerability standards were built for conventional software.

+

CVE identifies a flaw, CVSS scores its severity, and OSV maps it to a specific package and version range. This works because traditional vulnerabilities live in code you can pin to a release.

+

Agent component threats do not. A prompt injection hidden in an MCP tool description, a skill file that fetches its real instructions from a remote URL, a rug pull that changes behavior after install, a toxic flow that chains two individually-benign capabilities into an exfiltration path — none of these map to a package and version. The same malicious behavior appears in infinitely many textual forms, and the danger is in what the component does, not which dependency it pulls. That is the gap: the existing standards are blind to it because there is no package to flag and no version range to constrain.

+ +

What AVE is

+

AVE is an open standard that assigns a stable identifier to each distinct behavioral vulnerability class in agentic AI. Each record describes the behavior that makes a component dangerous, scores it with OWASP AIVSS v0.8, and maps it to the frameworks the field already uses. It is behavioral, not signature-based — one record catches many textual variants of the same underlying attack. AVE is a standard, not a product: the Bawbel scanner implements it, but it is designed to be implemented by anyone.

+ +

Why it wins

+
+
+ 01 +

Trusted frameworks

+

Every record maps to OWASP MCP Top 10, OWASP Agentic AI Top 10, and MITRE ATLAS, scored with OWASP AIVSS v0.8. AVE does not replace a framework — it gives teams a lintable way to enforce one.

+
+
+ 02 +

Scanner interoperability

+

Independent studies find different agent-security scanners barely agree on what they flag. That is a vocabulary problem, not a quality one. AVE is the shared reference that makes cross-tool findings comparable.

+
+
+ 03 +

Open governance

+

A standard owned by one company invites lock-in fear. AVE is Apache 2.0 with an explicit path toward neutral governance as an OWASP project — meant to outlive any single implementation.

+
+
+ +
+ The prize +

If the field adopts one vocabulary, findings from any tool interoperate and a security team can finally compare and correlate results across scanners. That is the position AVE is built to occupy — the CVE moment for AI agents.

+
+

anatomy → validation → consumption → output
+
+ +

Anatomy of a record

+

An AVE record is a single JSON file at records/AVE-YYYY-NNNNN.json that validates against schema/ave-record.schema.json (currently v1.1). It has two conceptual halves.

+ +
+
+

Definition — static

+
    +
  • ave_id — immutable identifier, never renumbered
    • +
  • attack_class — behavioral category
    • +
  • behavioral_fingerprint — what it does
    • +
  • severity · aivss — AIVSS v0.8 breakdown
    • +
  • owasp_mcp · owasp · mitre_atlas — mappings
    • +
  • remediation · iocs · references
    • +
+
+
+

Evidence declarations — v1.1

+
    +
  • confidence_baseline — base confidence
    • +
  • evidence_kind_default — default kind
    • +
  • detection_stage — earliest detectable
    • +
  • detection_layer — where it surfaces
    • +
  • evidence_basis_engines — which engines
    • +
  • derivable_into — toxic-flow chains
    • +
+
+
+

The static definition describes the vulnerability class itself and never changes per scan. ave_id is immutable — once published it is never renumbered or reused; a wrong record is deprecated via status, never deleted. behavioral_fingerprint is the heart of the record: it describes what the component does, not a byte signature. Severity and aivss_score must agree — CRITICAL implies a score of 9.0 or higher.

+

The evidence declarations were added in schema v1.1 (issues #69–72). They are all optional, so every pre-v1.1 record still validates. Crucially, they do not carry per-detection values — they declare the defaults and baselines a scanner uses to assign per-finding evidence metadata.

+ +

Validation — the record/rule/fixture triangle

+

A definition nobody can detect is not useful, and a detection with no false-positive guard is a liability. Every record therefore requires three things beyond the JSON:

+
    +
  • A rule (pattern, yara, or semgrep) that implements detection and references the ave_id.
    • +
  • A positive fixture — a file that must trigger the rule.
    • +
  • A negative fixture — a benign file that resembles the positive one but must not trigger. This is the false-positive guard, and a rule without one is incomplete.
    • +
+

The tooling in scripts/ enforces that every record has a rule and every rule has both fixtures. pytest runs the rules against the fixtures and fails if a positive fixture stops triggering or a negative fixture starts.

+ +

Consumption — the record declares, the scanner assigns

+

This is the most important concept for anyone implementing AVE, and the reason the v1.1 evidence fields exist.

+

An AVE record is static. A scanner Finding is a runtime instance — one detection of one file at one moment. Confidence belongs to the Finding, never to the record: the same class detected in a docs/ folder and in a live skill file deserves different confidence. So the record never carries a confidence number. It declares the baseline, and the scanner does the per-detection math.

+ + + + + + + + + + + + +
Record declares — staticScanner assigns to Finding — runtime
confidence_baseline→confidence (then FP-adjusted)
evidence_kind_default→evidence_kind
detection_stage→evidence_stage (floor)
evidence_basis_engines→evidence_basis
derivable_into→ToxicFlow.derived_from_findings
+ +
+ Core invariant +

In any Finding, confidence and aivss_score are separate fields with separate meaning and are never merged or substituted. AIVSS answers "how bad would this be"; confidence answers "how sure are we." A HIGH-severity low-confidence finding and a HIGH-severity high-confidence finding demand different responses, and the output keeps them distinct.

+
+ +
+ Why baselines live in the standard +

If the scanner hardcoded these baselines, a second implementation would invent its own and the two tools would produce divergent evidence metadata for the same class. Baselines belong in the standard so every implementation agrees. See docs/adr/0003-records-declare-baselines.md.

+
+ +

What stays out of the record

+

These are per-detection runtime values. They live only on the scanner Finding, never in an AVE record: confidence, confidence_band, the actual evidence_stage reached, confidence_reason, derived, line, match, suppressed, and the engine that actually fired.

+ +

Output and distribution

+
    +
  • SARIF. A scanner emits Findings as SARIF with the ave_id in ruleId and referenced under taxonomies, plus aivss_score, confidence, owasp_mcp, and mitre_atlas in the properties bag. Because SARIF is already consumed by the GitHub Security tab and CI, AVE ids travel into those surfaces for free.
    • +
  • PiranhaDB and the public site. The record set is ingested by PiranhaDB via the deploy-time sync_records.py export and served at api.piranha.bawbel.io and the public registry at ave.bawbel.io.
    • +
  • Crosswalks. Published mappings let other scanners' finding types resolve to AVE ids, so findings from different tools become comparable through the AVE layer.

It has +two conceptual halves. + +**The static definition** is the part that describes the vulnerability class +itself and never changes per scan: + +- `ave_id` — the immutable identifier. Once published it is never renumbered + or reused. A wrong record is deprecated via `status`, never deleted. +- `attack_class` — the behavioral category (for example + `external_instruction_fetch`), not a "vulnerability type" string. +- `behavioral_fingerprint` — what the component *does* that is dangerous. + Behavioral, not a byte signature. This is the heart of the record. +- `severity` and `aivss` — the OWASP AIVSS v0.8 breakdown (`cvss_base`, + `aars`, `thm`, `mitigation_factor`, `aivss_score`, `spec_version`). + Severity and score must agree: CRITICAL implies `aivss_score >= 9.0`. +- `owasp_mcp`, `owasp`, `mitre_atlas` — framework mappings. +- `remediation`, `indicators_of_compromise`, `references`. + +**The evidence declarations** were added in schema v1.1 (issues #69-72). +They are all optional, so every pre-v1.1 record still validates. They do not +carry per-detection values — they declare the *defaults and baselines* a +scanner uses to assign per-finding evidence metadata: + +- `confidence_baseline` — the base confidence for a single-engine match + before false-positive adjustment. +- `evidence_kind_default` — the default `evidence_kind` for findings of this + class. +- `detection_stage` — the earliest lifecycle stage at which this class is + detectable (`static_detection`, `runtime_observed`, `runtime_drift_detected`). +- `detection_layer` — where the class surfaces (`content`, `server_card`, + `registry_metadata`, `runtime`). +- `evidence_basis_engines` — which engines can detect this class. +- `derivable_into` — the toxic-flow chains this class can participate in. + +### Validation — the record/rule/fixture triangle + +A definition nobody can detect is not useful, and a detection with no +false-positive guard is a liability. Every record therefore requires three +things beyond the JSON: + +1. A **rule** (`pattern`, `yara`, or `semgrep`) that implements detection and + references the `ave_id`. +2. A **positive fixture** — a file that must trigger the rule. +3. A **negative fixture** — a benign file that resembles the positive one but + must *not* trigger the rule. This is the false-positive guard, and a rule + without one is incomplete. + +The validation tooling in `scripts/` enforces that every record has a rule +and that every rule has both fixtures. `pytest` runs the rules against the +fixtures and fails if a positive fixture stops triggering or a negative +fixture starts. + +### Consumption — the record declares, the scanner assigns + +This is the most important concept for anyone implementing AVE, and the +reason the v1.1 evidence fields exist. + +An AVE **record** is static. A scanner **Finding** is a runtime instance — +one detection of one file at one moment. Confidence belongs to the Finding, +never to the record: the same class detected in a `docs/` folder and in a +live skill file deserves different confidence. So the record never carries a +`confidence` number. Instead it declares the baseline, and the scanner does +the per-detection math: + +| Record DECLARES (static) | Scanner ASSIGNS to Finding (runtime) | +|---|---| +| `confidence_baseline` | `confidence` (then FP-adjusted) | +| `evidence_kind_default` | `evidence_kind` | +| `detection_stage` | `evidence_stage` (floor) | +| `evidence_basis_engines` | `evidence_basis` | +| `derivable_into` | `ToxicFlow.derived_from_findings` | + +The invariant that falls out of this: in any Finding, `confidence` and +`aivss_score` are separate fields with separate meaning and are never merged +or substituted. AIVSS answers "how bad would this be"; confidence answers +"how sure are we." A HIGH-severity, low-confidence finding and a HIGH-severity, +high-confidence finding require different responses, and the output keeps +them distinct. + +Putting the baselines in the standard rather than in scanner code is +deliberate. If the scanner hardcoded them, a second implementation would +invent its own and the two tools would produce divergent evidence metadata +for the same class. Baselines belong in the standard so every implementation +agrees. (See `docs/adr/0003-records-declare-baselines.md`.) + +### What stays out of the record + +These are per-detection runtime values. They live only on the scanner +Finding, never in an AVE record: `confidence`, `confidence_band`, the actual +`evidence_stage` reached, `confidence_reason`, `derived`, `line`, `match`, +`suppressed`, and the engine that actually fired. + +### Output and distribution + +- **SARIF.** A scanner emits Findings as SARIF with the `ave_id` in `ruleId` + and referenced under `taxonomies`, plus `aivss_score`, `confidence`, + `owasp_mcp`, and `mitre_atlas` in the properties bag. Because SARIF is + already consumed by the GitHub Security tab and CI systems, AVE ids travel + into those surfaces for free. +- **PiranhaDB and the public site.** The record set is ingested by PiranhaDB + (the deploy-time `sync_records.py` export) and served at + `api.piranha.bawbel.io` and the public registry at `ave.bawbel.io`. +- **Crosswalks.** Published mappings let other scanners' finding types + (SkillSpector's categories, ClawScan's types) resolve to AVE ids, so + findings from different tools become comparable through the AVE layer. + +### Adding a record + +Use the `add-ave-record` skill. To keep the standard current with real +research without padding it, use the `research-new-attack-classes` skill, +which benchmarks the threat landscape against existing records and only +proposes a new record when a genuinely distinct behavioral class exists. + +--- + +## Related documents + +- `schema/ave-record.schema.json` — the record schema (v1.1) +- `docs/guides/schema-vs-finding.md` — record vs Finding in depth +- `docs/adr/0001-behavioral-fingerprints.md` — behavioral over signature +- `docs/adr/0002-immutable-ave-id.md` — why ids never change +- `docs/adr/0003-records-declare-baselines.md` — the declares/assigns split +- `docs/guides/aibom-alignment.md` — how records feed an OWASP AIBOM diff --git a/docs/guides/aibom-alignment.md b/docs/guides/aibom-alignment.md new file mode 100644 index 0000000..e3d2516 --- /dev/null +++ b/docs/guides/aibom-alignment.md @@ -0,0 +1,16 @@ +# OWASP AIBOM Alignment + +AVE records feed the planned `bawbel abom` command (scanner repo, P2). + +An AIBOM (AI Bill of Materials, owaspaibom.org) is a CycloneDX-format +inventory of AI components.
