A single source file combines environment access, network access, and code or shell execution; review context before blocking.

Public source snippet (untrusted):

```javascript
L1: // src/serve.ts
L2: import { execFileSync, spawn } from "node:child_process";
L3: import { createServer } from "node:net";
L4: import { once } from "node:events";
...
L8: function resolveOpencodeBin() {
L9: const override = process.env.COTAL_OPENCODE_BIN?.trim() || process.env.COTAL_OPENCODE_RESOLVED_BIN?.trim();
L10: if (override) return override;
```

### 9. Critical: Reverse Shell
- **Category:** Source
- **Confidence:** 92.0%
- **Path:** dist/serve.js
- **Public source:** [View source](<https://unpkg.com/@cotal-ai/connector-opencode@0.50.0/dist/serve.js>)

Source matches reverse-shell style process and socket wiring.

Public source snippet (untrusted):

```javascript
L1: // src/serve.ts
L2: import { execFileSync, spawn } from "node:child_process";
L3: import { createServer } from "node:net";
L4: import { once } from "node:events";
...
L8: function resolveOpencodeBin() {
L9: const override = process.env.COTAL_OPENCODE_BIN?.trim() || process.env.COTAL_OPENCODE_RESOLVED_BIN?.trim();
L10: if (override) return override;
L11: if (process.platform !== "win32") return "opencode";
L12: for (const dir of (process.env.PATH ?? "").split(delimiter)) {
...
L31: async function killServe(serve) {
L32: if (serve.exitCode !== null || serve.signalCode !== null) return;
L33: serve.kill("SIGTERM");
```

### 10. High: Sandbox Evasion Gated Capability
- **Category:** Source
- **Confidence:** 84.0%
- **Path:** dist/serve.js
- **Public source:** [View source](<https://unpkg.com/@cotal-ai/connector-opencode@0.50.0/dist/serve.js>)

Source gates dangerous network, credential, or execution behavior behind CI, host, platform, time, or geo fingerprint checks.

Public source snippet (untrusted):

```javascript
L1: // src/serve.ts
L2: import { execFileSync, spawn } from "node:child_process";
L3: import { createServer } from "node:net";
L4: import { once } from "node:events";
...
L8: function resolveOpencodeBin() {
L9: const override = process.env.COTAL_OPENCODE_BIN?.trim() || process.env.COTAL_OPENCODE_RESOLVED_BIN?.trim();
L10: if (override) return override;
L11: if (process.platform !== "win32") return "opencode";
L12: for (const dir of (process.env.PATH ?? "").split(delimiter)) {
...
L31: async function killServe(serve) {
L32: if (serve.exitCode !== null || serve.signalCode !== null) return;
L33: serve.kill("SIGTERM");
```

### 11. High: Cross File Remote Execution Context
- **Category:** Source
- **Confidence:** 72.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@cotal-ai/connector-opencode@0.50.0/dist/index.js>)

Source spawns a local helper that also contains network and dynamic execution context; review data flow before blocking.

Public source snippet (untrusted):

```javascript
Cross-file remote execution chain: dist/index.js spawns dist/plugin.bundle.js; helper contains network access plus dynamic code execution.
L7: // src/extension.ts
L8: import { execFileSync } from "node:child_process";
L9: import { fileURLToPath } from "node:url";
...
L24: import { createHash, randomBytes } from "node:crypto";
L25: var SUN_PATH_MAX_BYTES = process.platform === "darwin" ? 104 : 108;
L26: function controlEndpoint(space, name, token = randomBytes(32).toString("base64url")) {
L27: const id = createHash("sha256").update(`${space}\0${name}\0${process.pid}\0${token}`).digest("base64url").slice(0, 32);
...
L116: const sourceKey = /* @__PURE__ */ new Map();
L117: for (const k of Object.keys(process.env))
L118: sourceKey.set(k.toLowerCase(), k);
...
L1809: error: new (_Err ?? $ZodErr
```

### 12. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 13. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 14. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 15. Critical: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@cotal-ai/connector-opencode@0.50.0/dist/index.js>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @cotal-ai/connector-opencode@0.49.0
matchedIdentity = npm:[redacted]:0.49.0
similarity = 0.667
summary = stored previous version shares package body but lacks this dangerous source file
