CVE-2026-68549

ClickMigrate is a database migration tool for ClickHouse with automatic SQL migration management and version tracking. Prior to version 1.0.3, a path traversal vulnerability in the revision command allowed a crafted migration name supplied via the -m argument to escape the intended migrations directory. Under specific conditions, an attacker could cause the tool to create a .sql file in an arbitrary location writable by the user executing the command. This issue is only exploitable if an attacker can influence the migration name passed to the revision command, such as through an insecure automation or CI/CD pipeline that forwards untrusted input. This issue has been patched in version 1.0.3.
