NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module.
NGINX Open Source has a vulnerability in the ngx_http_v3_module module.
When NGINX Plus or NGINX Open Source are configured to use the HTTP/3 QUIC module, an attacker may be able to spoof their source IP address allowing for bypass of authorization or bypass of rate limiting.
When NGINX Open Source is configured to proxy HTTP/2 traffic by setting proxy_http_version to 2, and also uses proxy_set_body, an attacker may be able to inject frame headers and payload bytes to the upstream peer.
