Only targets starting with a word character (`/etc`, + `/usr`) were ever blocked. `\b` now applies to the `$HOME` alternative alone, + where it is meaningful. + +- **HIGH — entropy suppression keyed off the absolute path** + (`scanners/entropy-scanner.mjs`). The test/fixture suppression rule matched + `/(test|spec|fixture|mock|__test__|__spec__)/i` against the **absolute** + path, so any directory name above the scan root silenced every entropy + finding in the entire target while still reporting status `ok`. The rule now + keys off the path relative to the scan root. + +- **HIGH — one unparseable JetBrains plugin crashed the whole ide-scan** + (`scanners/ide-extension-scanner.mjs`). The two manifest parsers disagree on + how they signal failure: `parseVSCodeExtension` returns bare `null`, + `parseIntelliJPlugin` returns a truthy `{ manifest: null, warnings }`. Only + the bare-null form was guarded, so every JetBrains failure path dereferenced + `manifest.hasSignature`; the TypeError escaped through `mapConcurrent`'s + unguarded `Promise.all` and aborted the scan of every other installed + extension. Guard widened, plus per-extension fault isolation at the call + site. + +- **HIGH — obfuscated injections were reported but not stripped** + (`scanners/content-extractor.mjs`). `stripInjection` scanned both the raw and + the decoded text but removed matches only via a literal replace against the + raw text. For a decoded-only match, `match[0]` is the decoded string, which + by construction does not occur in the raw text — so the replace was a silent + no-op and the encoded payload reached the LLM agent verbatim via + `sanitized_content`, alongside a finding announcing it. Every obfuscation the + normalizer exists to defeat was affected. Decoded-only matches are now + removed by redacting the source line; multi-line payloads that cannot be + attributed are flagged `unstripped: true` rather than left silently. + +- **Out-of-range numeric character reference emptied a plugin.xml field** + (`scanners/lib/ide-extension-parser.mjs`). `decodeEntities` guarded + `parseInt` with `Number.isFinite`, which bounds nothing, so any code point + above `0x10FFFF` made `String.fromCodePoint` raise `RangeError`. The + no-throw contract held (the per-field `safe()` wrapper catches it), but the + affected field was discarded and replaced with `''`. Undecodable references + are now left literal. Filed as HIGH; it is lower — such a document is not + well-formed XML, so the plugin would not load in IntelliJ either. + +### Changed + +- `stripInjection` (content-extractor) and `scanOneExtension` (ide-extension- + scanner) are exported for testing; `content-extractor.mjs` runs `main()` + behind the standard `isMain` guard so importing it no longer executes the + CLI.

Five defects from the v7.8.1 completion review, four sharing one failure mode: **the check reported success without running**. (1) `hooks/scripts/pre-bash-destructive.mjs` did not block `rm -rf /` or `rm -rf ~` — the target alternation `(?:\/|~|\$HOME)\b` ended in a word boundary that cannot hold after `/` or `~` at end-of-command, so the bare forms the rule is named for fell through to WARN (exit 0, command executed) while `/etc` and `$HOME` blocked normally, making the rule look functional from either end. (2) `scanners/entropy-scanner.mjs` matched its test/fixture suppression against the **absolute** path, so any ancestor directory named `test`/`spec`/`fixture`/`mock` silenced every entropy finding in the target while still returning status `ok`; it now keys off the relative path. (3) `scanners/ide-extension-scanner.mjs` guarded only `parseVSCodeExtension`'s bare-`null` failure signal, not `parseIntelliJPlugin`'s truthy `{ manifest: null, warnings }`, so any malformed JetBrains plugin dereferenced `manifest.hasSignature`; the TypeError escaped `mapConcurrent`'s unguarded `Promise.all` and aborted the scan of every other installed extension. Guard widened + per-extension fault isolation. (4) `scanners/content-extractor.mjs` — the remote-scan injection boundary — detected obfuscated injections but did not strip them: a decoded-only `match[0]` never occurs in the raw text, so the literal replace was a silent no-op and the payload reached the agent verbatim via `sanitized_content` alongside a finding announcing it. Removal is now line-level; unattributable multi-line payloads carry `unstripped: true`. This boundary had no direct test coverage before v7.8.2.

No +feature changes; full suite green at 1901/0 (1865 + 36 new regression tests). + +The common thread in four of the five is **silent failure**: the scanner or +hook reported success while the check it is named for did not run. That is the +worst failure mode for a security tool, because a clean report is +indistinguishable from a clean target. + +- **`hooks/scripts/pre-bash-destructive.mjs`** — the rule named "Filesystem + root destruction (rm -rf /)" did not block `rm -rf /`. Its target + alternation `(?:\/|~|\$HOME)\b` ended in a word-boundary assertion, which + cannot hold after `/` or `~` at end-of-command. Measured: `rm -rf /`, + `rm -rf ~`, `rm -rf /*`, `rm -fr /` and `sudo rm -rf /` all fell through to + WARN — advisory only, exit 0, command executed. `rm -rf $HOME` and + `rm -rf /usr` were blocked, which is why the gap survived: the rule looked + functional from either end. The `\b` now sits on the `$HOME` alternative + alone, so `$HOMEDIR` is still not swallowed. The prior test file had encoded + the defect as expected behaviour, with a NOTE attributing it to merged `-rf` + flags — a misdiagnosis, since `rm -rf /etc` blocks fine with merged flags. + +- **`scanners/entropy-scanner.mjs`** — the "test fixtures intentionally contain + example secrets" suppression matched against the **absolute** path. Any + ancestor directory name containing `test`, `spec`, `fixture` or `mock` + therefore suppressed every entropy finding in the whole target: a repository + cloned into a CI workspace, or checked out beneath a folder named `testing`, + reported zero secrets with status `ok`. The rule now keys off the path + relative to the scan root, which was already computed and passed alongside + it. Genuine fixture suppression (a `*.test.mjs` file, a relative `tests/` + directory) is unchanged. + +- **`scanners/ide-extension-scanner.mjs`** — `parseVSCodeExtension` signals + failure as bare `null`; `parseIntelliJPlugin` signals it as a **truthy** + `{ manifest: null, warnings }`. Only the former was guarded, so all five + JetBrains failure paths (no `lib/`, `lib/` not a directory, `lib/` + unreadable, no jars, no extractable jar) reached `manifest.hasSignature` and + threw. `mapConcurrent` awaited without a per-item catch, so `Promise.all` + rejected and the entire ide-scan aborted — one malformed plugin directory + took down the scan of every other installed extension, including, in an + audit context, a plugin that is malformed precisely because it is hostile. + +- **`scanners/content-extractor.mjs`** — this is the remote-scan indirection + layer: agents are supposed to see a sanitized evidence package, never raw + hostile content. `stripInjection` scanned the raw text *and* its decoded + form, but removed matches with `sanitized.replace(match[0], …)` against the + raw text only. A decoded-only `match[0]` does not occur in the raw text by + construction, so the replace silently did nothing: the payload was handed to + the agent verbatim through `sanitized_content` while the report announced a + critical injection. Removal now redacts the offending source line, since + decoding is not length-preserving and decoded offsets cannot be mapped back. + A payload split across several lines still cannot be attributed; those + findings carry `unstripped: true` instead of failing quietly. Whole-file + redaction was rejected — `normalizeForScan` base64-decodes any long blob, so + a benign asset could blank a file's entire evidence. + +- **`scanners/lib/ide-extension-parser.mjs`** — `decodeEntities` guarded + `parseInt` with `Number.isFinite`, which bounds nothing, so a character + reference above `0x10FFFF` raised `RangeError` in `String.fromCodePoint`. + Contrary to how this was filed, the documented no-throw contract held: the + per-field `safe()` wrapper catches it. The real effect was quieter — the + field was replaced with `''`, so a `` carrying one such reference + parsed as an empty name and name-based checks (JetBrains typosquat + detection) ran against nothing. Severity is below HIGH: a document with a + code point above `0x10FFFF` is not well-formed XML, so IntelliJ would reject + the plugin as well. Undecodable references are now left literal. + +## v7.8.1 — Auto-cleaner command-injection fix (CRITICAL) + +Security patch for a CRITICAL defect introduced with the v7.8.0 auto-cleaner +hardening pass. No feature changes; full suite green at 1865/0. + +`scanners/auto-cleaner.mjs` validated candidate `.mjs`/`.js`/`.cjs` content by +shelling out to ``node --check "${tmpPath}"`` via `execSync`. `tmpPath` is +derived from the finding's `file` field — an untrusted scanned-repo filename. +The F-2 containment guard that landed in v7.8.0 verifies the resolved path +stays inside the scanned tree, but performs no shell-metacharacter handling, so +a filename whose `"` terminates the interpolated quote injects a second +command. Because `/security clean` runs in live mode by default, scanning a +hostile repository was sufficient to execute attacker-chosen commands locally. +The defect was reproduced with a live proof-of-concept before being fixed. + +Both subprocess sites now use `spawnSync` with an argv array — the syntax check +and the CLI's inline scan-orchestrator fallback — so no shell interprets a path. +As defense-in-depth, `applyFixes()` additionally refuses any finding whose +`file` carries shell or control metacharacters, surfacing it as `skipped`. + +Regression coverage is deliberately split across both layers +(`tests/scanners/auto-cleaner-rce.test.mjs`): one test drives `validateContent` +directly to prove the shell is gone, because the metacharacter guard would +otherwise stop the hostile input before it reached the sink and the test would +pass without testing the fix. + +## v7.8.0 — Trigger, signature, and AST-taint scanners + +Three new deterministic deep-scan scanners (TRG/SIG/AST), each with its own finding prefix, OWASP/AST mapping, policy block, fixtures, and graceful-skip behaviour.
