This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The most notable finding, CVE-2026-42010, could allow authentication bypass if RSA-PSK cipher suites are enabled, but this requires a non-default configuration. CVE-2017-11164 could cause denial of service only if user-supplied regular expressions are processed by PCRE, which is not typical for ClickHouse. Disabling RSA-PSK or restricting access to PCRE-dependent features would eliminate these risks.
