CVE-2026-48772 ProxySQL: PROXY-Protocol-v1 UNKNOWN parses spoofed source IP, bypassing mysql_query_rules.client_addr ACL
ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. In versions 2.0.0 through 3.0.8, the ProxySQL MySQL frontend accepts the PROXY UNKNOWN \r\n PP1 frame as a well-formed PROXY protocol header. The HAProxy PROXY protocol v1 specification says that when the protocol token is UNKNOW...
Use of Less Trusted Source
Overview Affected versions of this package are vulnerable to Use of Less Trusted Source. Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded request headers it receives from untrusted proxies to downstream services. Both the WebFlux and WebMVC Gateway Servers process these...
GHSA-2VQW-3MP8-CGMX Puma PROXY Protocol v1 Accepts Repeated Protocol Headers on Persistent Connections
Impact Puma is vulnerable to source IP spoofing when setremoteaddress proxyprotocol: :v1 is enabled and persistent connections are used. PROXY protocol v1 is a connection-level protocol. Support was added to Puma in v5.5.0. A proxy sends one PROXY header at the beginning of a TCP connection, befo...
