SCA: security update for github.com/lucasdillmann/nginx-ignition (GHSA-jr34-h97m-9hpx)

high Tenable Self-Hosted Container Security Plugin ID 448254

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - nginx ignition is a user interface for the nginx web server. In versions 2.29.0 through 2.40.0, the gin
 i18n middleware in nginx-ignition's API server runs in front of every HTTP request and calls
 `golang.org/x/text/language.ParseAcceptLanguage` on the raw `Accept-Language` header without imposing any
 size or shape filter. The underlying parser has quadratic-time behaviour on long lists of malformed
 language tags. The CVE-2022-32149 guard that golang.org/x/text added in v0.3.8 caps the number of `-`
 characters in the input at 1000, but it does not cap `_` characters even though the parser's internal
 scanner aliases `_` to `-` before parsing. A single unauthenticated GET request with an `Accept-Language`
 header built out of `_` separators burns about 2.4 seconds of server CPU on the host running nginx-
 ignition; ten concurrent attackers saturate a ten-core box for the duration of the attack while consuming
 ~10 MiB/s of upstream bandwidth. Version 2.40.1 fixes this issue. (CVE-2026-61629)

Solution

Update the github.com/lucasdillmann/nginx-ignition library and its related packages to version 0.0.0-20260526022344-0c988fc1277c or later.
