Vulnerability from github – Published: 2026-10-14 15:32 – Updated: 2026-10-14 15:32

Details

Description NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_v3_module module. When using HTTP/3 with

proxy_request_buffering on directive, an unauthenticated attacker may be able to inject data in the proxied request.
