The last version of zlib integrated in CMake 3.28.1 is version 1.2.12.

However zlib version 1.2.13 fixes CVE-2022-37434 ([NVD - CVE-2022-37434](https://nvd.nist.gov/vuln/detail/CVE-2022-37434)).

When do you plan to integrate version 1.2.13 of zlib into CMake?

I think an issue at [CMake / CMake · GitLab (kitware.com)](https://gitlab.kitware.com/cmake/cmake) is a better choice here.

Updating zlib is nothing complicated, see the previous update to 1.2.12: [zlib: update to version 1.2.12 (!7302) · Merge requests · CMake / CMake · GitLab (kitware.com)](https://gitlab.kitware.com/cmake/cmake/-/merge_requests/7302)
