help request: Will APISIX be affected by the vulnerability CVE-2026-42533?

### Description

APISIX is built upon Nginx, and most versions of Nginx are affected by this vulnerability. So, does APISIX need to be upgraded?

### Environment

- APISIX version (run `apisix version`): 3.2.0、3.13.0
- Operating system (run `uname -a`):
- OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
- etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
- APISIX Dashboard version, if relevant:
- Plugin runner version, for issues related to plugin runners:
- LuaRocks version, for installation issues (run `luarocks --version`):

Start by reviewing CVE-2026-42533 and comparing its affected Nginx versions with the Nginx or OpenResty version reported by `nginx -V` or `openresty -V`. Check the APISIX 3.2.0 and 3.13.0 environments, then document whether APISIX is affected and whether an upgrade is required.
