Together they share three +cross-cutting decisions that have to be made once, consistently, not five times +independently: what `detection_layer` value code-implementation vulnerabilities get, +how the `Tool Abuse` attack_class category should (or shouldn't) stretch to cover +code-level flaws instead of prompt-driven ones, and what order to ship them in given the +different rule-engine shapes they need. Treating this as a batch also matches the +skill's own framing in the benchmark report: 5 candidates from one research pass, not +five unrelated submissions. + +--- + +## Problem + +The 2026-07-10 benchmark (Phases 1-3) found 5 CRITICAL/HIGH-severity attack classes with +NVD-confirmed or named-trusted-vendor primary sources that AVE's current 51 records do +not cover, verified against the deletion test in ADR-0001's spirit (behavior, not +strings). All 5 were confirmed by the maintainer and have open GitHub issues +(#32-#36). This PRD is the implementation plan for turning those 5 issues into +published records with working detection. + +## Goals + +1. Five new AVE records, each schema-valid against `schema/ave-record-1.1.0.schema.json`. +2. Each record has at least one detection rule in `bawbel/scanner` (coordinated PR) with + a positive and negative fixture, per the record → rule → fixture triangle + (`ARCHITECTURE.md`). +3. Resolve the naming/taxonomy questions flagged as "open to discussion" in issues + #32-#36 once, consistently, rather than ad hoc per record. +4. Keep the standard's existing boundary intact: behavioral fingerprints, not byte + signatures; no enforcement-tool config in `mitigation` (Section 0 of the v1.1.0 + migration brief still governs). + +## Non-goals + +- Adding the `owasp_ast` field (flagged as future work in the v1.1.0 migration brief + Section 7; not blocking this batch — issues #32-#36 already note "TBD" for it). +- Resolving the OAuth consent-hijack borderline candidate from the benchmark report. It + was flagged, not confirmed, and stays a research note in `docs/agents/research/` until + someone decides it clears AVE's component-behavior boundary. +- Independently re-verifying the NSA/CISA `CSI_MCP_SECURITY` PDF (direct fetch returned + 403 during research). It's corroborating context for issue #34, not the sole citation + — #34 stands on the OX Security report and CSA research notes regardless. +- Any change to `add-ave-record` or `research-new-attack-classes` skill mechanics. + +--- + +## Open decisions (need an answer before Phase 5 implementation starts) + +### Decision 1 — `detection_layer` for code-implementation vulnerabilities + +Issues #32 (`tool-implementation-command-injection`) and #33 +(`mcp-resource-path-traversal`) both describe a flaw in a tool's **own server-side +handler code** (CWE-78, CWE-22) — not in a skill's natural-language content, which is +what every existing `content`-layer record describes. The schema's `detection_layer` +enum is fixed: `content | server_card | registry_metadata | runtime | transport`. None +of these precisely names "the vulnerable code is the tool's own implementation, found by +SAST/code review of source, not by scanning prompt text." + +Both issues currently propose `content` as "closest existing enum value" with an +explicit flag that this stretches the taxonomy. Three options: + +- **(a) Reuse `content`.** No schema change, ships immediately. Costs a small semantic + overload: `content` now means both "natural-language instruction text" and "the tool's + own source code," which a future reader of `docs/architecture/ave-architecture.md`'s + five-layer table won't expect. Cheapest, and matches how AVE already tolerates + `detection_layer` being a coarse five-bucket classification rather than a precise + scanner-routing key (see `evidence_basis_engines` as the actual routing signal). +- **(b) Add a sixth enum value** (e.g. `implementation`). This is a structural schema + change under CONTRIBUTING.md's "Schema changes" section — requires its own issue and a + 30-day comment period before merging, which blocks this entire batch on a slower + track than the records themselves need. +- **(c) Leave `detection_layer` as `content` but make the distinction explicit in + `behavioral_fingerprint` text only**, no schema change. Functionally identical to (a) + with a documentation convention layered on top. + +**Recommendation: (a)/(c) combined** — reuse `content`, and require +`behavioral_fingerprint` for these two records to state explicitly that the vulnerable +surface is the tool's *own implementation code*, not its declared instructions (both +draft fingerprints in #32/#33 already do this). Revisit as a real `(b)` schema-change +proposal only if a *third* code-implementation-vulnerability class shows up in a future +research pass — one overloaded bucket is a documentation note, three is a pattern that +earns its own enum value. This keeps the batch un-blocked and defers the schema question +until there's enough evidence to answer it well. + +**RESOLVED 2026-07-10:** adopted as written — `detection_layer: content` for #32 and +#33, `behavioral_fingerprint` states the implementation-code surface explicitly, no +schema change opened. Applied starting with #32. + +### Decision 2 — `attack_class` category for #32 + +#32 proposes `Tool Abuse - Implementation Command Injection`, flagged in the issue as +"may warrant its own category distinct from Tool Abuse" since every other `Tool Abuse - +*` record is prompt-driven. Recommend keeping it under `Tool Abuse` for this batch (least +taxonomy churn, and `attack_class` is free text, not an enum, so it costs nothing to +rename later without a schema change) rather than inventing a new top-level category for +one record. Revisit alongside Decision 1 if the pattern recurs. + +### Decision 3 — severity presentation for #35 + +CVE-2025-32711 (EchoLeak) carries two different CVSS scores from two different assessors +(NIST 7.5 HIGH, Microsoft CNA 9.3 CRITICAL). The issue recommends the record state both +rather than picking one. Confirm: does AVE's `severity` field (single enum value) force a +choice, with the dual-score nuance living only in `references`/`description` prose? If +so, recommend `severity: HIGH` as the more conservative of the two (NIST's independent +assessment over the affected vendor's own CNA rating), with the AARF/`aivss.notes` field +carrying the Microsoft 9.3 figure as context. This is a real precedent-setting call for +the *next* multi-assessor CVE too, not just this record. + +--- + +## Scope — the five records + +| Issue | attack_class (draft) | detection_layer | Rule engine(s) | Sequencing rationale | +|---|---|---|---|---| +| [#32](https://github.com/bawbel/ave/issues/32) tool-implementation-command-injection | `Tool Abuse - Implementation Command Injection` | `content` (Decision 1) | semgrep, pattern | **Done: AVE-2026-00052.** AIVSS computed 7.5 HIGH (not the CRITICAL estimate); rationale in aivss.notes. `rules/pattern/` reference rule written in this repo (matches the corpus-wide convention — `rules/semgrep/`/`rules/yara/` are empty scaffolding for all 51 prior records too; the real semgrep implementation is the `bawbel/scanner` coordinated PR, still outstanding). | +| [#33](https://github.com/bawbel/ave/issues/33) mcp-resource-path-traversal | `Tool Abuse - Resource Path Traversal` | `content` (Decision 1) | semgrep, pattern | **Done: AVE-2026-00053.** AIVSS computed 6.3 MEDIUM (general-class score; notes explain a scanner may score an individual finding higher when the traversal target is known). `bawbel/scanner` PR outstanding, same as #32. | +| [#36](https://github.com/bawbel/ave/issues/36) code-execution-sandbox-escape | `Execution Hijack - Code Execution Sandbox Escape` | `runtime` | pattern, sandbox, llm | **Done: AVE-2026-00054.** AIVSS computed 6.7 MEDIUM. `component_type: tool` (not `mcp_server`).

Closest parent would be AVE-2026-00051 (OAuth Discovery Rebinding), but the mechanism is different (social-engineered consent redirect vs. tampered discovery metadata). Leaning **OUT OF SCOPE** per the same reasoning AVE already applies to model-layer ATLAS techniques, but flagging rather than deciding, since it sits closer to AVE's boundary than a clear-cut case. | + +--- + +## Phase 2 benchmarking detail — why each NEW CLASS candidate isn't already covered + +**#1 tool-implementation-command-injection vs. AVE-2026-00004 (Shell Pipe Injection) / AVE-2026-00033 (Unsafe Deserialization):** +00004 and 00033 both describe a skill's *natural-language content* instructing the agent +to construct and run a dangerous command — the vulnerability is in what the text tells +the LLM to do. CVE-2026-0755 is a classic CWE-78 flaw in the MCP *tool's own server-side +handler code* (`execAsync`): a crafted tool-call *parameter value* reaches an unsanitized +shell call with no LLM reasoning involved at all — a non-agentic attacker could trigger +it by sending a raw JSON-RPC request. Different mechanism, different detection method +(SAST/code review of server source vs. content-layer prompt scanning). Fails the "fold +it in and lose nothing" test — folding it into 00004 would erase the distinction between +prompt-driven misuse of a legitimate capability and a code-level injection bug in the +capability's own implementation. + +**#2 mcp-resource-path-traversal vs. AVE-2026-00022 (Scope Creep):** +00022 is content-layer: a skill's text instructs the agent to *ask for* out-of-scope +resources. The three path-traversal CVEs are CWE-22 flaws in a resource/file handler's +own path-validation logic, triggered by a parameter value regardless of any instruction +content. Same distinction as #1 — code vulnerability vs. prompt-driven overreach. + +**#3 mcp-stdio-launch-config-injection vs. AVE-2026-00001 (Metamorphic Payload) / AVE-2026-00034 (Dynamic Skill Import):** +Both existing records describe a component's *content* fetching or loading new +instructions at runtime — the LLM is still in the loop, executing instructions found in +fetched data. The STDIO flaw happens *before any protocol handshake or LLM reasoning*: +untrusted data in the `command`/`args` config fields used to spawn the MCP server +subprocess is executed directly by the OS. Confirmed via direct technical read +(penligent.ai) as explicitly distinct from prompt injection: "the attacker's goal may +not be to make the model say something unsafe... [it manipulates] the boundary between +configuration and process creation." + +**#4 rendered-content-autofetch-exfiltration vs. AVE-2026-00026 (Output Encoding) / AVE-2026-00039 (Covert Channel):** +This is the closest call. 00026 is exfiltration *through a tool call parameter*; 00039 +is steganographic *hiding* of data in visible output text for later decoding. EchoLeak's +mechanism needs neither: a plain, unobfuscated markdown image reference in the agent's +own answer is automatically fetched by the *client's rendering layer*, causing an +outbound request with no tool call and no encoding step. The distinguishing behavior is +"the answer itself is the beacon, and the renderer sends it for free." I believe this +clears the bar, but flagging the adjacency explicitly since it's the least clear-cut of +the five. + +**#5 code-execution-sandbox-escape vs. AVE-2026-00042 (REPL Code Mode Payload Injection):** +00042 is about how malicious code *gets into* the agent's generated code (data breaking +into code context via poisoned tool results). CVE-2026-5752 is about what happens *after* +code is already running inside an intended sandbox: a JavaScript prototype-chain +traversal breaks the isolation boundary to root-level host execution — a flaw in the +sandbox's own containment, exploitable even by code the agent was *authorized* to run. +Different point in the kill chain (content-to-code vs. code-to-host), different defense +(input/context separation vs. isolation hardening). + +--- + +## What I did not do + +Per the skill's hard rule 6 ("report and stop before implementing — never auto-create +records without confirmation") and the zoom-out protocol ("do not edit during +zoom-out"): no GitHub issues opened, no records/rules/fixtures created.
