CVE-2026-34189 · Severity: info · Published 2026-10-01

Pandora FMS is a comprehensive monitoring and management platform used by organizations to track infrastructure and applications. A Cross-Site Request Forgery (CSRF) vulnerability allows an attacker to trick an authenticated administrator into visiting a malicious webpage, which then deletes event responses without the administrator's knowledge. This could result in loss of alert data and disruption of incident response workflows.
