- TLS Certificate Verification Is Disabled for Authenticated Notion API Requests<![CDATA[ ## Vulnerability Details **File Location**: `scripts/sync_stars_to_notion_db.py`, lines 6-9, 91, 111, 122, and 157 **Vulnerability Type**: Improper certificate validation **Risk Level**: High ### Vulnerable Code ```python try: import requests import urllib3 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) except ImportError: print("The 'requests' library is required. Install it using: pip install requests") sys.exit(1) ``` Every authenticated Notion request explicitly disables certificate validation: ```python response = requests.post(url, headers=HEADERS, json=payload, verify=False) ``` ```python response = requests.post(query_url, headers=HEADERS, json=payload, verify=False) ``` ```python requests.patch( patch_url, headers=HEADERS, json={"archived": True}, verify=False ) ``` ```python response = requests.post(url, headers=HEADERS, json=payload, verify=False) ``` ### Technical Analysis The script sends the `NOTION_API_KEY` in the HTTP `Authorization` header: ```python HEADERS = { "Authorization": f"Bearer {NOTION_TOKEN}", "Content-Type": "application/json", "Notion-Version": NOTION_VERSION } ``` Although the destination uses HTTPS, `verify=False` instructs `requests` not to authenticate the server certificate. Suppressing `InsecureRequestWarning` further conceals this unsafe condition from the user. An attacker who can intercept or redirect traffic can present an arbitrary TLS certificate and impersonate `api.notion.com`. This may be possible through a hostile network, compromised DNS, malicious proxy configuration, or an untrusted local root/proxy environment. The attacker could then obtain: - The Notion integration bearer token. - Repository names, owners, categories, URLs, and star counts. - Notion database and page identifiers. - API responses returned by the impersonated service. The same weakness applies to destructive `PATCH` requests used to archive database recor ...[truncated 1662 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove `verify=False` from every `requests.post` and `requests.patch` call. The default certificate validation behavior should be retained: ```python response = requests.post( url, headers=HEADERS, json=payload, timeout=30 ) ``` 2. Remove the global warning suppression: ```python urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) ``` 3. If a private enterprise CA is genuinely required, accept a user-configured CA bundle rather than disabling verification: ```python ca_bundle = os.environ.get("REQUESTS_CA_BUNDLE") response = requests.post( url, headers=HEADERS, json=payload, verify=ca_bundle if ca_bundle else True, timeout=30 ) ``` 4. Validate that `NOTION_API_KEY` is present before constructing or sending any request. 5. Add explicit connection and read timeouts to every request. 6. Rotate any Notion token that has already been used with this version of the script over an untrusted network. ]]>
