CVE-2026-40083: Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have SQL Injection through unsanitized unserialize+implode in managers.php. At line 7

highCVSS 7.2CVE-2026-40083
Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have SQL Injection through unsanitized unserialize+implode in managers.php. At line 756 of managers.php, the application assigns $selected_items by calling cacti_unserialize(stripslashes(gnrv('selected_graphs_array'))). The cacti_unserialize() function calls unserialize() with allowed_classes set to false, which prevents object injection but still allows arbitrary string arrays to be deserialized. Then, at lines 760 to 766, the deserialized array values are passed directly into db_execute('DELETE FROM snmpagent_managers WHERE id IN (' . implode(',', $selected_items) . ')'), where they are imploded into the SQL statement without any integer validation, resulting in SQL Injection when using SNMP agent management permissions. This issue has been fixed in version 1.2.31.
