Overview
Upgrades Nginx to v1.31.0 to address CVE-2026-42945, a heap buffer overflow in
ngx_http_rewrite_moduleaffecting Nginx versions through 1.30.0. The upstream fix shipped in mainline 1.31.0 (and stable 1.30.1); this image stays on the mainline channel.See F5 advisory K000161019 for the vulnerability description.
Changes
nginx:1.31.0-trixie. Picks up the upstream fix for CVE-2026-42945. No config changes.-bookwormtag for 1.31.0, so the Debian variant moves to Trixie.Risk
Low for the Nginx bump itself (same mainline channel, no config changes). The Debian Bookworm -> Trixie change is a base-OS upgrade and brings a newer glibc, OpenSSL and apt source layout. Downstream images that install extra packages on top of this base (notably
docker-nginx-proxy) should be smoke-tested after rebuild to confirm apt sources and module ABIs still resolve. Consumers will pick up the fix oncedocker-nginx-proxyis bumped in a follow-up PR.Related
