Historical version

This is version 4, as it stood on . It is not what this organization currently publishes — read the current version.

Critical PHP Vulnerability (CVE-2026-109618, CVE-2026-109619) [infocon yellow], (Wed, Oct 21st)

SANS Internet Storm Center Version 4 imported change

Imported from official source

PHP.net announced that it will release a critical update today. We decided to change the infoCon to YELLOW due to the widespread use of PHP, the expected severity of the flaw (CVSS 9.4), and the availability of early PoC exploits ahead of the patch becoming available.
