| Doc Text: |
A flaw was found in Apache HttpComponents Client, specifically in its classic input/output (I/O) model. When processing a response message with an invalid or unsupported `Content-Encoding` header, the client fails to properly release the underlying network connection. This connection leak can lead to the exhaustion of the connection pool, making the service unavailable and resulting in a Denial of Service (DoS) for legitimate users.
