    CVE-2026-116366 first CVE on my name just dropped. unauthenticated RCE on any @ClickHouseDB instance using just the public service hostname. special thanks to San and the ClickHouse security team. the report was accepted within 20 minutes on Bugcrowd. P.S. Clickhouse Security Team emailed me 1 hour before I reported the vulnerability stating that they "detected attempts of unauthenticated RCE on my instance" which shows how seriously they approach the security of their service in general.
