## Security analysis

### Published attack-surface review

- **Summary:** The package entrypoint sends browser cookies in a request body. This exposes cookie data to the handler at /addPost.

- **Trigger:** Loading index.js in a browser context where fetch and document are available.

- **Impact:** Cookies accessible to the script, potentially including session credentials, are disclosed to the endpoint.

- **Evidence paths:** package.json, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-26T01:29:41.587Z

### AI review details

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

- **Mechanism:** The code serializes document.cookie into a JSON field and POSTs it to /addPost.

- **Attack narrative:** When the entrypoint runs in a browser context, it reads document.cookie and sends the value in a POST request to the current origin's /addPost route. Cookies available to script may include session credentials.

- **Rationale:** The manifest points to code that actively transmits browser cookie data without a consent check. This is concrete credential exposure, so the package should be blocked.

- **Files touched:** index.js

- **Network endpoints:** /addPost

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json names index.js as the package entrypoint., index.js sends document.cookie in a POST request to /addPost.
