| Doc Text: |
A flaw was found in Tinyproxy. This vulnerability allows unauthenticated remote attackers to gain unauthorized access to internal proxy statistics or misroute requests. This is possible due to improper validation of the Host header during stathost detection, which can be exploited by injecting a matching Host header or manipulating ports to bypass detection. The primary impact is the circumvention of access controls, leading to potential information disclosure and redirection of network traffic.
