Reporting a Vulnerability
We're extremely grateful for security researchers and users that report vulnerabilities to the ClickHouse Open Source Community. All reports are thoroughly investigated by developers.

When Should I Report a Vulnerability?
- You think you discovered a potential security vulnerability in ClickHouse
- You are unsure how a vulnerability affects ClickHouse

Security Vulnerability Response
Each report is acknowledged and analyzed by ClickHouse maintainers within 5 working days. As the security issue moves from triage, to identified fix, to release planning we will keep the reporter updated.
Public Disclosure Timing
A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect the report date to disclosure date to be on the order of 7 days.
