Category Description

Platform-specific updates

Made these platform-specific updates:

Platform Update

PHP

Turned off the session.upload_progress.enabled setting by default on all PHP platform branches, and fatal_error_backtraces on PHP 8.5. If your application requires either setting, you can turn it back on by adding a .ini file whose name sorts after aws.ini (for example, zz-custom.ini). For details, see Extending php.ini.

Turning off these settings partially mitigates CVE-2026-109618 and CVE-2026-109619. For details, see the PHP security announcement. The PHP 8.5 and PHP 8.4 platform update and the PHP 8.3 and PHP 8.2 platform update include the PHP versions that address these issues.
