A flaw was found in curl. This vulnerability can lead to information disclosure by inadvertently revealing authentication credentials. When curl retrieves credentials from a local configuration file (such as a .netrc file), requesting the effective URL metadata can cause the returned destination address to improperly include those secret credentials. A local user may exploit this issue to view sensitive authentication tokens if an application or script queries and logs or displays the resolved URL.
