CWE: CWE-502 \u2014 Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

Code:
	public void readData(LPDataInput input) {
		super.readData(input);
		pos = input.readInt();
		if (pos != -1) {
			isNBT = input.readBoolean();
		} else {
			ignoreData = input.readBitSet();
			ignoreNBT = input.readBitSet();
		}
	}
