CVE-2026-39893

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

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
