    CRLF Injection

    Affected versions of this package are vulnerable to CRLF Injection in the newInitialMessage function of HttpProxyHandler when header validation is explicitly disabled and user-influenced outboundHeaders are added without sanitization. An attacker can inject arbitrary HTTP headers into proxy requests by supplying malicious header values containing CRLF sequences.

    Notes:

    • This is only exploitable if the application uses HttpProxyHandler with user-influenced outboundHeaders and does not perform its own CRLF sanitization on header values.

    • This is caused due to an incomplete fix for CVE-2025-67735.

    How to fix CRLF Injection?

    Upgrade io.netty:netty-handler-proxy to version 4.1.133.Final, 4.2.13.Final or higher.
