PHP 8.5.12 was released on 21 October 2026 to fix two critical remote code execution vulnerabilities (CVE-2026-109618 and CVE-2026-109619).
My Azure App Service is configured to use the Latest platform release channel, but it is still running PHP 8.5.11.
Will Microsoft automatically roll out the patched PHP version, and is there anything I can do to obtain the update sooner, or do I need to wait for Microsoft's rollout?
Thanks.
