ydb-go-sdk is a pure Go native and database/sql driver for the YDB platform. Since ydb-go-sdk v3.48.6 if you use a custom credentials object (implementation of interface Credentials it may leak into logs. This happens because this object could be serialized into an error message using fmt.Errorf("something went wrong (credentials: %q)", credentials) during connection to the YDB server. If such logging occurred, a malicious user with access to logs could read sensitive information (i.e. credentials) information and use it to get access to the database. ydb-go-sdk contains this problem in versions from v3.48.6 to v3.53.2. The fix for this problem has been released in version v3.53.3. Users are advised to upgrade. Users unable to upgrade should implement the fmt.Stringer interface in your custom credentials type with explicit stringify of object state.
