Description

Piwigo is a full featured open source photo gallery application for the web. Prior to 16.4.0, check_upgrade_access_rights() in admin/include/functions_upgrade.php conditionally escapes the submitted username only when the removed get_magic_quotes_gpc function exists, so PHP 8 and later concatenate an unauthenticated username directly into the upgrade authentication SQL query. When database upgrades are pending, a crafted query result can satisfy the status and password checks, set PHPWG_IN_UPGRA
