CWE	CWE-319: Cleartext Transmission of Sensitive Information
OWASP	A03:2017 - Sensitive Data Exposure
Confidence Level	Medium
Impact Level	Medium
Likelihood Level	Medium

Description

Disabling TLS verification by setting NODE_TLS_REJECT_UNAUTHORIZED to 0 or using rejectUnauthorized: false allows connections to untrusted servers. This bypasses certificate validation and makes secure connections insecure.

Impact

Attackers can intercept and read sensitive data by performing man-in-the-middle attacks, since the application will trust any server, even malicious ones. This can lead to data theft, account compromise, and loss of user trust.
