## Verdict summary
**Blocked & quarantined** — May bias a reviewer toward dismissing potential concerns; no runtime attack behavior was identified.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.0-next.359
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The nonstandard manifest prose makes categorical claims aimed at preempting review of security-relevant package behavior, which meets the reviewer-manipulation rule. I found no separate runtime attack chain, but the review manipulation itself is evidence of malicious intent.

## Security analysis

### Published attack-surface review

- **Summary:** Nonstandard manifest prose appears designed to steer security review of package behavior.

- **Trigger:** Reading package.json during package review.

- **Impact:** May bias a reviewer toward dismissing potential concerns; no runtime attack behavior was identified.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T18:29:09.178Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Comment-like \`//...\` metadata makes unsolicited, categorical claims about lifecycle safety and other manifest choices.

- **Attack narrative:** The package embeds unusually specific, unsolicited assurances in nonstandard manifest fields, including a claim that its prepack script has no install impact. This appears to steer review conclusions. The compiled entry points otherwise appear to be ordinary export barrels, and no runtime attack behavior was identified.

- **Rationale:** The nonstandard manifest prose makes categorical claims aimed at preempting review of security-relevant package behavior, which meets the reviewer-manipulation rule. I found no separate runtime attack chain, but the review manipulation itself is evidence of malicious intent.

- **Files touched:** package.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 87.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json contains nonstandard \`//...\` fields with unusually detailed claims about how reviewers should interpret exports, dependencies, lifecycle behavior, and side effects; one says the prepack guard “cannot break the install it has no business touching.”, The declared scripts include a \`prepack\` guard but no install, preinstall, or postinstall hook., The package entry points are export barrels that expose browser and node primitives.

- **Evidence against:** No network, process execution, or filesystem operations were found in the compiled library search., The manifest identifies the package as Theia and GLSP client primitives and lists framework dependencies consistent with that purpose.

## Affected versions and remediation

This report applies to @hydranium/glsp-client-theia@1.0.0-next.359.

- Avoid installing @hydranium/glsp-client-theia@1.0.0-next.359. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 2. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** style/diagram-loading.css
- **Public source:** [View source](<https://unpkg.com/@hydranium/glsp-client-theia@1.0.0-next.359/style/diagram-loading.css>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

### 3. High: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 87.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@hydranium/glsp-client-theia@1.0.0-next.359/package.json>)

package.json contains nonstandard \`//...\` fields with unusually detailed claims about how reviewers should interpret exports, dependencies, lifecycle behavior, and side effects; one says the prepack guard “cannot break the install it has no business touching.”

Public source snippet (untrusted):

```json
"//prepack": "The publish guard, a `prepack` rather than a `prepare`: `prepack` runs only when a tarball is made (`npm pack`, `npm publish`) and never on install, so it cannot break the install it has no business touching. What it defends against: `files` lists `lib`, `lib` is gitignored, and a `files` entry matching nothing is skipped SILENTLY — so `npm publish` from an unbuilt tree emits a tarball of `src` and nothing else, with no error.",
  "//sideEffects": "A stylesheet IS the side effect: `style/diagram-loading.css` is pulled in by a bare import in `browser/diagram-widget.j
```

### 4. High: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 87.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@hydranium/glsp-client-theia@1.0.0-next.359/package.json>)

The declared scripts include a \`prepack\` guard but no install, preinstall, or postinstall hook.

Public source snippet (untrusted):

```json
"scripts": {
    "build": "tsc -b tsconfig.browser.json",
    "clean": "rimraf lib tsconfig.tsbuildinfo tsconfig.browser.tsbuildinfo",

### 5. High: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 87.0%
- **Path:** lib/index.js
- **Public source:** [View source](<https://unpkg.com/@hydranium/glsp-client-theia@1.0.0-next.359/lib/index.js>)

The package entry points are export barrels that expose browser and node primitives.

Public source snippet (untrusted):

```javascript
// CSS loader. It is a frontend entry and nothing else. Node-side primitives
// (connection-handler wiring) stay behind
// `@hydranium/glsp-client-theia/node` so the `@theia/core/lib/node/...`
// imports don't leak into a browser bundle.
__exportStar(require("./browser/index"), exports);
//# sourceMappingURL=index.js.map
```

### 6. High: Ai Review Evidence

The package entry points are export barrels that expose browser and node primitives.
