⛔️ Error

🔒 Professional Plan

The requests package includes a number of standard methods for accessing HTTP servers. The common parameter in these methods is verify to denote whether to verify the server's host certificate. If unset, the default value is True to verify. However, by setting the value to False, the code is subject to a number of security risks including:

Man-in-the-middle attacks
Session hijacking
Data theft

Example

Error

import requests

requests.get("https://localhost", verify=False)

Remediation

fix

Setting the value of the verify argument to True or removing the keyword argument accomplish the same effect of ensuring that certificates are verified.

import requests

requests.get("https://localhost", verify=True)

False Positives

In the case of a false positive the rule can be suppressed. Simply add a trailing or preceding comment line with either the rule ID (PY523) or rule category name (improper_certificate_validation).
