CVE-2026-46531 — MEDIUM (5.5)

Vulnerability Description

Cacti is an open source performance and fault management framework. From version 1.2.27 to before version 1.2.31, Cacti contains an authenticated stored second-order SQL injection in the automation tree rule item handler. A user holding the Automation realm (default General Administration role) can persist an arbitrary SQL fragment in the automation_tree_rule_items.field column. The fragment is later concatenated directly into a SELECT ... AS source FROM ... clause in lib/api_automation.php :: create_all_header_nodes() and executed when an administrator triggers automation via the standard graphs.php?action=actions&drp_action=8 ("Apply Automation Rules") bulk action. The result of the injected SELECT is written into graph_tree_items.title and rendered in the Cacti tree UI, providing a direct exfiltration channe. This issue has been patched in version 1.2.31.
