Security Hotfix

We released an updated ea-nginx package family (nginx 1.31.3) for EasyApache 4.

This security release resolves three nginx vulnerabilities, including a critical heap buffer overflow in the map directive with regular expressions (CVE-2026-42533) that could allow remote code execution or a worker process denial of service, plus a memory disclosure in the slice module (CVE-2026-60005) and a use-after-free in the SSI module (CVE-2026-56434). The ea-nginx module packages (ea-nginx-echo, ea-nginx-headers-more, ea-nginx-njs, ea-nginx-passenger, and ea-modsec30-connector-nginx) rebuild against the new nginx.
