// KNOWN, ACCEPTED GAP: the CVE's own PoC token is a real Salesforce session

// — the closest parallel to the sibling signature's own AWS
// `AKIAIOSFODNN7EXAMPLE` carve-out — Salesforce's OWN documentation
// explaining the `<org-id>!<signature>` token FORMAT with an example
// token, which is prose about a shape, not a leaked secret. None of these
// are in the tiny 6-7 phrase benign corpus this signature was tested
// against, which is exactly the "corpus tests the wrong slice of the

// detector family. The `!` was REMOVED rather than patched around it (same
// choice as TODOS #56/#57: prefer a narrower, unmodified, already-validated

// CVE's own literal PoC token (with `!`) now scores `pass` against this
// signature — see TODOS #53's writeup. The signature still generalizes to

//
// Overlap, not a bug: a vendor-prefixed token disclosed with a literal

// pre-merge adversarial review's 28 findings, and why this gate is
// narrower than an earlier draft. Three structural shapes share one
// signature id, all requiring the SAME literal bridge-call gate:
//
// 1. An HTML tag with an inline event-handler attribute (a generic
// `\son[a-z]+\s*=`, not an enumerated handler list — HTML has no
// non-event `on*` attribute, and this closes a review-found gap where
// `onmouseout`/`onblur`/etc. weren't on the original enumerated list)
// whose VALUE contains the bridge call — the CVE-2025-68669 shape.
// Value-scoped via a lookahead so the token must be INSIDE the
// attribute's own value; the bare/unquoted branch additionally
// requires `(?!["'])` so it cannot fall through past a real quoted
// value into an ADJACENT attribute when the two abut with no
// separating whitespace (review-found regex-correctness bug).
// 2. A <script>...</script> block whose body (bounded to 2000 chars,
// never crossing a closing </script>) contains the bridge call. The
// tag-open matcher is quote-aware (`(?:"[^"]*"|'[^']*'|[^>"'])*`) so a
// literal `>` inside a quoted attribute value can't be mistaken for
// the tag's own close and misalign where the 2000-char body budget
// starts counting from (review-found: this could push a real call
// just past the budget, causing a missed detection).
// 3. A markdown code fence tagged `mermaid` or `echarts` (the two plugin
// types both disclosed CVEs abuse) containing the bridge call
// ANYWHERE in the fence body — the CVE-2026-22793 shape. An earlier
// draft instead matched `new Function(`/IIFE syntax with NO call
// gate, on the premise that legitimate diagram/option content never
// contains a function definition; the review found that premise FALSE
// for ECharts specifically (formatter callbacks persisted via
// `new Function(...)`, option data computed via an IIFE, are both
// standard documented idioms) and, independently, that requiring
// IIFE/`new Function(` syntax at all was unnecessarily narrow: the
// vulnerable `parseOption` wraps the ENTIRE fence body in
// `new Function('return {' + body + '}')()`, so a bridge call placed
// directly as an object-literal property value (no wrapper at all)
// executes identically. Requiring only the bridge call is both safer
// (fixes the ECharts false-positive class) and strictly more complete.
//
// All three regexes use bounded lazy quantifiers ({0,4000}?/{0,2000}?)
// with a `(?!` "does not cross a fence/tag-close boundary" guard rather
// than an unbounded `[\s\S]*` scan — measured against multi-hundred-KB
// adversarial padding (including many non-matching `electron.mcp.`-prefixed
// near-misses) with no backtracking blowup (sub-millisecond).
//
// Severity is `high` (→ warn, forward + log, never block on its own): a
// documentation/CVE-lookup tool can legitimately return prose QUOTING this
// exact literal call (a GHSA/NVD advisory explaining the vulnerability) —
// an accepted, low-frequency residual the review confirmed and this
// signature does not try to special-case away, the same "ambiguous but
// real" tier as credential-egress-in-response, and the project's own
// repeated lesson that a wrong BLOCK on a block-capable carrier is the
// worse failure direction (v0.29.0 / v0.31.0).
//
// `redact: true` — a review finding (not merely FP/evasion) caught that
// shapes 2-3's lazily-bounded match can capture arbitrary attacker-placed
// text between the tag/fence open and the bridge call verbatim into the
// excerpt (e.g. a secret the injected script reads before exfiltrating
// it), which would otherwise land unredacted in guard-events.jsonl and the
// public `guard inspect` seam even while a co-firing credential signature
// on the SAME leaf correctly redacts it — silently defeating the
// redaction guarantee tool_response carries elsewhere in this file.

The\n // tag-open matcher is quote-aware (`(?:\"[^\"]*\"|'[^']*'|[^>\"'])*`) so a\n // literal `>` inside a quoted attribute value can't be mistaken for\n // the tag's own close and misalign where the 2000-char body budget\n // starts counting from (review-found: this could push a real call\n // just past the budget, causing a missed detection).\n // 3.

Drift\n * detection at runtime compares the live tools/list response against\n * the pin and blocks if the hash has changed — catching rug-pull attacks\n * structurally, complementing the regex-based pattern engine.\n *\n * Storage:\n * ~/.mcpm/pins.json — pin data, JSON, format_version-tagged\n * ~/.mcpm/pins.json.integrity — SHA-256 of pins.json contents (sidecar)\n *\n * The integrity sidecar (security review F4.2 / issue #19) is an UNKEYED SHA-256\n * of pins.json stored next to it with the same 0o600 perms (the sidecar write\n * itself now lives in the shared store-integrity.ts). It provides\n * INTEGRITY (tamper-EVIDENCE against accidental corruption / cross-machine\n * copies / a different OS-user account), NOT AUTHENTICITY against a\n * same-user/postinstall attacker: any process that can write pins.json can\n * also recompute and rewrite this sidecar to match, so there is no\n * attacker/writer asymmetry. A keyed scheme (HMAC/signature) would need a\n * secret the writable store lacks — same constraint as the secret store\n * (security issue #15); deferred to OS-keychain support. See security issue\n * #19. Any mismatch on read refuses to use the pin file until the user runs\n * `mcpm guard reset-integrity`.\n *\n * writePins finalizes via two sequential renames (content, then sidecar) —\n * see its own doc comment. readPins retries a mismatch briefly (TODOS #24)\n * so a reader landing in that window doesn't fail closed on an in-flight\n * write; a real tamper or a crash mid-write still reproduces every attempt.\n *\n * Two-target scope: install-time capture writes captured_via:\"install\".\n * If install-time spawn fails (OAuth, network), a placeholder entry with\n * current_hash:null + captured_via:\"first-session\" is written; the next\n * successful runtime tools/list fills the hash.\n */\n\nimport { createHash } from \"node:crypto\";\nimport { readFile, writeFile, unlink } from \"node:fs/promises\";\nimport { fileSha, writeFileAtomic } from \"./store-integrity.js\";\nimport path from \"node:path\";\nimport lockfile from \"proper-lockfile\";\nimport { z } from \"zod\";\nimport { getStorePath } from \"../store/index.js\";\n\nconst PINS_FILENAME = \"pins.json\";\nconst INTEGRITY_FILENAME = \"pins.json.integrity\";\n\nexport const PINS_FORMAT_VERSION = 1;\n\nexport type CapturedVia = \"install\" | \"first-session\" | \"backfill\";\n\n/**\n * H4: per-field SHA-256 hashes of the SAME canonical leaves that feed\n * {@link hashToolDefinition}.

Before this command the benchmark's reference adapter\n * vendored an esbuild bundle of patterns+signatures, which (a) silently drifts\n * from the shipped engine and (b) gave mcpm a privileged in-process path that no\n * other guard being scored could have. This command is the level playing field:\n * every guard, mcpm included, is measured through its own published CLI.\n *\n * Contract (depended on by external adapters — treat as semi-stable):\n * - input is ONE JSON frame (pretty-printed is fine) or NDJSON, one per line\n * - `--json` writes exactly one verdict object per input frame, in INPUT\n * ORDER — positional correlation is what lets a harness zip verdicts back\n * to its own case ids without mcpm needing to know about them\n * - an unparseable frame yields `{\"action\":\"error\"}`, never a silent skip and\n * never a fabricated \"pass\" (a harness must be able to tell \"my guard said\n * this is safe\" apart from \"my guard fell over\")\n *\n * The verdict comes from `inspectFrame` — the SAME stateless composition the\n * relay enforces (signature patterns + the F5 exfil-param key walker + the H7\n * server-initiated content scan), including the warn-only carrier clamp, so a\n * `resources/read` injection reports `warn` here exactly as it would in-line.\n * v0.25.0 shipped this command calling `inspectMessage` alone, which silently\n * reported `pass` on frames the relay blocks for 3 of the 12 catalog\n * signatures; `inspect-relay-parity.test.ts` now pins the equivalence.\n *\n * Excluded by design, because they are not properties of the frame: schema and\n * handshake drift (needs the pin store and per-session state) and policy\n * overrides (mute/log_only).

// one digit — which the English phrase "Bearer token" / "Bearer
// credential" (short, no digits) and multi-word prose (spaces break the

//
// KNOWN, ACCEPTED GAP: the CVE's own PoC token is a real Salesforce session
// id, shaped `<15-char org id>!<signature>`. An earlier version of this

// — the closest parallel to the sibling signature's own AWS
// `AKIAIOSFODNN7EXAMPLE` carve-out — Salesforce's OWN documentation
// explaining the `<org-id>!<signature>` token FORMAT with an example
// token, which is prose about a shape, not a leaked secret. None of these
// are in the tiny 6-7 phrase benign corpus this signature was tested
// against, which is exactly the "corpus tests the wrong slice of the
// input space" lesson TODOS #52's own review already logged for this
// detector family. The `!` was REMOVED rather than patched around it (same
// choice as TODOS #56/#57: prefer a narrower, unmodified, already-validated

// CVE's own literal PoC token (with `!`) now scores `pass` against this
// signature — see TODOS #53's writeup. The signature still generalizes to
// any OTHER Bearer-disclosed JWT or opaque session token, which is the
// majority shape this class of vulnerability takes outside Salesforce's
// own token format.
//
// Overlap, not a bug: a vendor-prefixed token disclosed with a literal

// TODOS #54 — renderer-code-execution-in-response. See the
// ELECTRON_MCP_BRIDGE_CALL comment above for the full CVE grounding, the
// pre-merge adversarial review's 28 findings, and why this gate is
// narrower than an earlier draft. Three structural shapes share one
// signature id, all requiring the SAME literal bridge-call gate:
//
// 1. An HTML tag with an inline event-handler attribute (a generic
// `\son[a-z]+\s*=`, not an enumerated handler list — HTML has no
// non-event `on*` attribute, and this closes a review-found gap where
// `onmouseout`/`onblur`/etc. weren't on the original enumerated list)
// whose VALUE contains the bridge call — the CVE-2025-68669 shape.
// Value-scoped via a lookahead so the token must be INSIDE the
// attribute's own value; the bare/unquoted branch additionally
// requires `(?!["'])` so it cannot fall through past a real quoted
// value into an ADJACENT attribute when the two abut with no
// separating whitespace (review-found regex-correctness bug).
// 2. A <script>...</script> block whose body (bounded to 2000 chars,
// never crossing a closing </script>) contains the bridge call. The
// tag-open matcher is quote-aware (`(?:"[^"]*"|'[^']*'|[^>"'])*`) so a
// literal `>` inside a quoted attribute value can't be mistaken for
// the tag's own close and misalign where the 2000-char body budget
// starts counting from (review-found: this could push a real call
// just past the budget, causing a missed detection).
// 3. A markdown code fence tagged `mermaid` or `echarts` (the two plugin
// types both disclosed CVEs abuse) containing the bridge call
// ANYWHERE in the fence body — the CVE-2026-22793 shape. An earlier
// draft instead matched `new Function(`/IIFE syntax with NO call
// gate, on the premise that legitimate diagram/option content never
// contains a function definition; the review found that premise FALSE
// for ECharts specifically (formatter callbacks persisted via
// `new Function(...)`, option data computed via an IIFE, are both
// standard documented idioms) and, independently, that requiring
// IIFE/`new Function(` syntax at all was unnecessarily narrow: the
// vulnerable `parseOption` wraps the ENTIRE fence body in
// `new Function('return {' + body + '}')()`, so a bridge call placed
// directly as an object-literal property value (no wrapper at all)
// executes identically. Requiring only the bridge call is both safer
// (fixes the ECharts false-positive class) and strictly more complete.
//
// All three regexes use bounded lazy quantifiers ({0,4000}?/{0,2000}?)
// with a `(?!` "does not cross a fence/tag-close boundary" guard rather
// than an unbounded `[\s\S]*` scan — measured against multi-hundred-KB
// adversarial padding (including many non-matching `electron.mcp.`-prefixed
// near-misses) with no backtracking blowup (sub-millisecond).
//
// Severity is `high` (→ warn, forward + log, never block on its own): a
// documentation/CVE-lookup tool can legitimately return prose QUOTING this
// exact literal call (a GHSA/NVD advisory explaining the vulnerability) —
// an accepted, low-frequency residual the review confirmed and this
// signature does not try to special-case away, the same "ambiguous but
// real" tier as credential-egress-in-response, and the project's own
// repeated lesson that a wrong BLOCK on a block-capable carrier is the
// worse failure direction (v0.29.0 / v0.31.0).
//
// `redact: true` — a review finding (not merely FP/evasion) caught that
// shapes 2-3's lazily-bounded match can capture arbitrary attacker-placed
// text between the tag/fence open and the bridge call verbatim into the
// excerpt (e.g. a secret the injected script reads before exfiltrating
// it), which would otherwise land unredacted in guard-events.jsonl and the
// public `guard inspect` seam even while a co-firing credential signature
// on the SAME leaf correctly redacts it — silently defeating the
// redaction guarantee tool_response carries elsewhere in this file.

The\n // tag-open matcher is quote-aware (`(?:\"[^\"]*\"|'[^']*'|[^>\"'])*`) so a\n // literal `>` inside a quoted attribute value can't be mistaken for\n // the tag's own close and misalign where the 2000-char body budget\n // starts counting from (review-found: this could push a real call\n // just past the budget, causing a missed detection).\n // 3.

The tool builds a `kubectl` invocation by string-concatenating\n * `resourceName`/`namespace`/etc. into one command string, then does a naive\n * `command.split(\" \")` before `spawn()` — every OTHER tool in the same codebase\n * uses the safe array-based `execFileSync(argsArray)` pattern, so this is a\n * single-tool regression. Splitting on whitespace lets an attacker embed a\n * second CLI flag inside a string argument that should be a bare identifier;\n * the advisory's PoC is `resourceName: \"my-database --address=0.0.0.0\"`, which\n * turns a normally localhost-only port-forward into one bound on all\n * interfaces, exposing an internal database to the network (CVSS 8.3 HIGH).\n *\n * Same key-first design as #50/#51 (and shares their walker,\n * tool-call-args-walk.ts): `tool_call_args` carries no schema context at call\n * time, so a blanket value-only regex would false-positive on any tool whose\n * arguments legitimately carry flag-shaped text (e.g. a config/CLI-passthrough\n * field). Only testing the value when the key's canonical form names a scalar\n * namespace/opaque-identifier field scopes this to the CVE's shape.\n *\n * `name` is DELIBERATELY EXCLUDED from the key scope, same as #50/#51 — an\n * earlier version of this file included it (reasoning: the CVE's own\n * vulnerable argument is `resourceName`, and \"no real name contains a literal\n * ` --word` substring\"). A pre-merge adversarial review measured that claim\n * and found it FALSE, with five independently-reproduced real shapes: a\n * ticket/PR/task title mentioning a flag by name (`task_name: \"Add --dry-run\n * support to sync command\"`, lifted verbatim from this project's own commit\n * history), a compound `*_name` key whose OTHER token already marks it as a\n * free-text CLI-passthrough field (`flag_name`, `option_name`, `script_name`\n * under npm's own documented `<script> -- <flags>` convention), and a\n * freeform cloud-resource \"Name\" tag carrying an appended operational note\n * (`resource_name: \"prod-db-01 --do-not-delete\"`). That last shape is\n * structurally IDENTICAL to the CVE's own PoC (a single-token prefix, a\n * space, then a `--word` token) — there is no regex-level distinction between\n * an injected flag and a benign operational annotation on a \"name\"-shaped\n * field, because the ambiguity is semantic (does the wrapped tool interpret\n * the flag?), not structural. Excluding `name` closes all five measured FP\n * classes; the accepted cost is that the advisory's own literal PoC (via\n * `resourceName`) now scores `pass`. The SAME vulnerable code path is still\n * caught via `namespace` (named as an equally vulnerable argument by the\n * advisory itself, and namespaces are a far more constrained value space by\n * convention — a k8s namespace is a short DNS-label token, never a\n * multi-word phrase).

Before this command the benchmark's reference adapter\n * vendored an esbuild bundle of patterns+signatures, which (a) silently drifts\n * from the shipped engine and (b) gave mcpm a privileged in-process path that no\n * other guard being scored could have. This command is the level playing field:\n * every guard, mcpm included, is measured through its own published CLI.\n *\n * Contract (depended on by external adapters — treat as semi-stable):\n * - input is ONE JSON frame (pretty-printed is fine) or NDJSON, one per line\n * - `--json` writes exactly one verdict object per input frame, in INPUT\n * ORDER — positional correlation is what lets a harness zip verdicts back\n * to its own case ids without mcpm needing to know about them\n * - an unparseable frame yields `{\"action\":\"error\"}`, never a silent skip and\n * never a fabricated \"pass\" (a harness must be able to tell \"my guard said\n * this is safe\" apart from \"my guard fell over\")\n *\n * The verdict comes from `inspectFrame` — the SAME stateless composition the\n * relay enforces (signature patterns + the F5 exfil-param key walker + the H7\n * server-initiated content scan), including the warn-only carrier clamp, so a\n * `resources/read` injection reports `warn` here exactly as it would in-line.\n * v0.25.0 shipped this command calling `inspectMessage` alone, which silently\n * reported `pass` on frames the relay blocks for 3 of the 12 catalog\n * signatures; `inspect-relay-parity.test.ts` now pins the equivalence.\n *\n * Excluded by design, because they are not properties of the frame: schema and\n * handshake drift (needs the pin store and per-session state) and policy\n * overrides (mute/log_only).
