CVE-2025-6491

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts. %if 1 The php package contains the module (often referred to as mod_php) which adds support for the PHP language to Apache HTTP Server when running in prefork mode. This module is deprecated. %endif
