Description

Server-Side Request Forgery (CWE-918) in Kibana allows authenticated users with connector management privileges to bypass the operator-configured connection allowlist. By configuring a Webhook connector with a crafted target, an attacker can cause Kibana to issue outbound requests to destinations that the egress restriction controls were intended to block.

Affected configurations

• elastic kibana (>= 9.0.0 < 9.2.8) • elastic kibana (>= 9.3.0 < 9.3.2)
