Updated PHP Windows builds for Brotli security fix

The PHP team announces updated Windows builds: PHP 8.5.12-1, 8.4.27-1, 8.3.36-1 and 8.2.35-1. These builds include Brotli 1.2.1, which fixes CVE-2026-111497, an out-of-bounds write vulnerability in Brotli decompression.

In PHP Windows builds, the vulnerable decoder can be reached through the cURL extension when automatic HTTP response decompression is enabled. This is disabled by default in cURL, but applications and HTTP client libraries can enable it.

The -1 suffix identifies a Windows package rebuild with updated dependencies. These builds use the same PHP source releases, and the PHP runtime versions remain unchanged.

The updated packages are available on the downloads page.
