Cacti: Pre-authentication SQL injection via rfilter RLIKE clause in graph_view.php_CVE-2026-39893

{
    "lastseen": "",
    "description": "Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request variable was concatenated into a RLIKE SQL clause without sanitization. The endpoint does not require authentication (graph viewing supports guest access via the configured guest user), so the SQLi was reachable pre-auth on installs with guest viewing enabled. This issue was fixed in version 1.2.31.",
