Vulnerability Type: Improper TLS certificate validation and permitted plaintext transport
Risk Level: HighVulnerable Code

(this may take a few seconds)`); // 确定是使用 HTTP 还是 HTTPS const isHttps = NEWS_EXTRACTOR_SERVER_URL.startsWith('https://'); const httpModule = isHttps ? https : http; try { // 构建请求选项 const serverUrl = new URL(NEWS_EXTRACTOR_SERVER_URL); const requestData = JSON.stringify({ news_content: content }); const endpoint = '/api/v1/analyze'; const options = { hostname: serverUrl.hostname, port: serverUrl.port || (isHttps ? 443 : 80), path: endpoint, method: 'POST', headers: { 'Content-Type': 'application/json', 'Content-Length': Buffer.byteLength(requestData), 'X-EasyAlpha-API-Key': EASYALPHA_API_KEY, 'Authorization': `Bearer ${EASYALPHA_API_KEY}` }, // 默认跳过 SSL 验证以简化用户操作 (尤其是针对 duckdns 等自动证书可能导致的验证问题) // 如果用户显式设置了 ALLOW_INSECURE_SSL='false'，则开启验证 rejectUnauthorized: process.env.ALLOW_INSECURE_SSL === 'false' ? true : false };Technical Analysis
The HTTPS request configuration disables certificate validation by default. The
rejectUnauthorizedoption becomesfalseunlessALLOW_INSECURE_SSLis explicitly set to the exact stringfalse. Consequently, the client does not reliably authenticate the remote server, defeating a primary security guarantee of TLS.The server URL is configurable and the implementation explicitly selects Node.js's plaintext
httpmodule for URLs that do not start withhttps://. No validation prevents API credentials and ...[truncated 2588 chars]- Remediation

Remediation Suggestions
-
Remove the
rejectUnauthorizedoverride and rely on Node.js's secure default certificate validation:javascript const options = { hostname: serverUrl.hostname, port: serverUrl.port || 443, path: endpoint, method: 'POST', headers: { 'Content-Type': 'application/json', 'Content-Length': Buffer.byteLength(requestData), 'Authorization': `Bearer ${EASYALPHA_API_KEY}` } }; -
Enforce HTTPS before constructing the request:
javascript const serverUrl = new URL(NEWS_EXTRACTOR_SERVER_URL); if (serverUrl.protocol !== 'https:') { throw new Error('NEWS_EXTRACTOR_SERVER_URL must use HTTPS'); } -
If local plaintext development is necessary, restrict it to loopback hosts through a separate, explicit development option. Do not permit arbitrary remote HTTP destinations.
-
For private or development certificates, accept a user-provided trusted certificate authority through the
caoption rather than disabling certificate validation globally. -
Send the API key in only the authentication header required by the service. Remove the duplicate credential header to reduce exposure through middleware and access logs.
-
Add automated tests confirming that:
- invalid or self-signed certificates are rejected by default;
- arbitrary
http://server URLs are rejected; - only an explicitly approved loopback development configuration can use plaintext transport; and
- credentials are emitted through only one required header.
-
Update the documentation's claim of secure communication only after secure TLS validation and HTTPS enforcement are implemented.
