netty: io.netty/netty-handler-proxy: Netty: HTTP Header Injection via HttpProxyHandler Disabled Validation

A flaw was found in Netty. The HttpProxyHandler component, which handles HTTP CONNECT requests, does not properly validate user-provided outbound headers. This allows an attacker to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server. This could lead to unexpected...

netty-codec-haproxy: Netty HAProxy PROXY protocol v2 codec: Denial of Service via memory leak from crafted PROXY protocol headers

A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested PP2TYPESSL type-length-value TLV records. This can lead to a memory leak, causing the underlying cumulation...

CVE-2025-3110

A flaw in OpenVPN Access Server allows remote attackers to smuggle HTTP requests when the server operates behind a reverse proxy. The issue stems from the server accepting unstandardized bare line-feed sequences in HTTP headers. Mitigation To mitigate this issue, ensure that any reverse proxy...
