Overview
Affected versions of this package are vulnerable to Race Condition via the Request function in the client.go file. An attacker can access or leak proxy configuration and potentially sensitive data by exploiting concurrent requests that mutate shared HTTP client properties without synchronization.
Note: This is only exploitable if multiple goroutines or asynchronous request methods are used with differing proxy configurations.
