Vulnerability in PHP 8.0. This (CVE-2026-35048)

Summary

Vulnerability in PHP 8.0. This (CVE-2026-35048). Successful exploitation can lead to full system takeover.

Original description

The description as published by the source.

The Piwigo installer in versions 16.3.0 and earlier accepts POST parameters for database configuration and writes them directly into a PHP configuration file without proper sanitization. On PHP 8+, the addslashes() protection is bypassed because it checks for get_magic_quotes_gpc(), a function removed in PHP 8.0. This allows raw user input to be interpolated directly into PHP source code. An unauthenticated attacker can inject arbitrary PHP code through POST parameters (prefix, dbpasswd, dbhost, dbname, or dbuser), which gets written to local/config/database.inc.php and executed on every page load.
