Description OSIDB Bzimport 2026-10-14 14:52:01 UTC 
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.

Impact


This vulnerability may allow remote attackers to 

inject data in the proxied request.  There is no control plane exposure; this is a data plane issue only.
