nginx: check the October fixes against the modules you actually use

Five medium-severity advisories share fixed minimums of stable 1.30.6 and mainline 1.31.7. Configuration still matters.

What changed

The October 14 nginx releases address five medium-severity issues. The fixed minimums are stable 1.30.6 and mainline 1.31.7; later patched releases can also be used. These are minimums for this batch, not a claim that 1.31.7 is today’s newest mainline.

Who should check

The advisories concern alias/rewrite handling (CVE-2026-15176), script evaluation (93479), HTTP/3 request bodies (95101), TLS session tickets (97629) and asynchronous file I/O (97205). All five identifiers use the CVE-2026 prefix. Check each affected range and relevant feature rather than assuming every installation exposes every issue.

What to do

Identify the nginx instance that terminates real traffic, including ingress and reverse-proxy containers.
Compare its upstream version or distribution security backport with the official advisory. Keep your deployment on a compatible supported branch.
Validate the proposed configuration with nginx -t, then test routing, static files, TLS and any enabled HTTP/3 in staging. Schedule the normal service replacement or reload.

Reference commands

Inspect the installed binary and validate configuration

nginx -v
nginx -V
nginx -t

Verify the result

Confirm the active service uses the corrected binary after deployment; replacing a file on disk is not proof. Keep the previous image or package and configuration available for rollback.

Goal: apply the documented workflow to my development project.
Read the existing project instructions, inspect the relevant files and explain the smallest useful setup.

Use the article and its examples as references. Identify any missing project files before making changes.

If I have not supplied a project folder, ask which development project to use. Do not invent a repository URL.

Additional project setup instructions:
Review my nginx deployment against https://nginx.org/en/security_advisories.html and the October 14, 2026 releases. Inventory the running binary/container, package vendor, enabled modules and configuration without exposing secrets. Check CVE-2026-15176, CVE-2026-93479, CVE-2026-95101, CVE-2026-97629 and CVE-2026-97205. Upstream fixed minimums are stable 1.30.6 and mainline 1.31.7; verify newer patched releases or distribution backports. Do not assume all installations enable all affected features. Propose a compatible local update, nginx -t validation, staging checks, running-version verification and rollback plan. Do not reload or replace a production proxy without approval.

Check the dated advisory and current official vendor guidance. Identify whether my installed version and configuration are affected before proposing a fix.

Give me a short plan, then make the agreed local changes and run the relevant checks. Report actual results and anything not verified. Stop before credentials, paid services, production changes, push, merge or deployment.
