**Name of the Vulnerable Software and Affected Versions**
Vector versions prior to 0.55.0
**Description**
The ClickHouse sink contains a SQL/identifier injection flaw. The software escaped the `table` identifier but interpolated the `database` value raw into the INSERT statement, allowing a crafted database value to break out of identifier quoting. This occurs in the `KeyPartitioner::partition()` function via the `set uri query` parameter, which could allow attackers to access sensitive database information using crafted SQL statements.
**Recommendations**
Update to version 0.55.0.
