ClickHouse Server: unauthenticated remote code execution (CVE-2026-116366)
ClickHouse fixed a flaw in ClickHouse Server that, under certain conditions, lets an unauthenticated user with network access run arbitrary code on the server (CVE-2026-116366, CWE-190 integer overflow, CVSS 4.0 score 9.5 critical). Fixes shipped Oct 30 2026 in v26.3.62.3-lts, v26.8.36.3-lts, v26.9.27.3-stable and v26.10.3.7-stable. ClickHouse says the fix is already applied to all ClickHouse Cloud and BYOC deployments, so self-hosted servers are the ones that need upgrading. The bug was reported by researcher Elshad Toklayev through ClickHouse's bug bounty. No public exploit or in-the-wild exploitation has been reported.
