+# Use of GET request method with sensitive query strings (Authorization header details)
+
+## Description
+
+The authorization header value was identified in the request URL. These headers typically contain
+usernames and passwords or JWT tokens. These values should never be sent in GET requests as they
+maybe captured by proxy systems, stored in browser history, or stored in log files. If an attacker
+were to get access to these logs or logging systems, they would be able to gain access to the
+target account.
+
+## Remediation
+
+Authorization header details should never be sent in GET requests. When transmitting sensitive information
+such as JWT tokens, always use POST requests or headers to transmit the sensitive data.
