Description

A flaw was found in libcurl. When configured to use a .netrc file for credentials and follow HTTP redirects, libcurl can inadvertently send the password from the initial connection to the redirected host. This sensitive information disclosure occurs when both the original and redirect URLs use clear text HTTP, are performed over the same HTTP proxy, and the same connection is reused. This vulnerability, categorized as an Exposure of Sensitive Information to an Unauthorized Actor (CWE-200), could allow an attacker to obtain user credentials.
