Summary

The ClickHouse database has been employing fuzzing techniques for a while, and recent collaborations with security teams and researchers have led to the discovery of new issues and edge cases. The WINGFUZZ team's innovative fuzzing engine generates semantically correct SQL sequences with abundant types by utilizing metadata-based grammar-free mutation and type-affinity based sequence generation. This approach allows ClickHouse to explore a larger input space, generating more test cases than other fuzzers, and has been successfully integrated into the company's daily development process, ensuring security and reliability in each version of the product.
