How to fix?

Upgrade Minimos:latest nginx-1.30-mod-stream_geoip2 to version 1.30.1-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nginx-1.30-mod-stream_geoip2 package and not the nginx-1.30-mod-stream_geoip2 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
