CVE-2026-55841: Graylog Vulnerable Fortigate Syslog Event Parsercve-2026-55841-graylog-vulnerable-fortigate-syslog-event-parser
Use of GLFortiGateSyslogEvent parser wrapper detected. This parser contains flawed field sanitization logic that deletes top-level syslog fields if embedded key-value pairs exist within field values, enabling log evasion and field tampering. Use the standard FortiGateSyslogEvent from syslog4j instead.
